Cart-oh-nono #1: blending choropleths and basemaps
The first post in an occasional series pointing out why what you think is a good idea for your map might not be so cool after all.
Here's a choropleth map. It doesn't matter what it's showing but the use of colour to conotate low to high is fairly easily understood. Yellow is seen as 'low' and as you move through to red you see something that means 'more'.
This works because we see light as less and dark as more and this colour ramp fits that schema. There are 6 colours on this map. We can differentiate them pretty easily. We can therefore easily establish which countries share similar characteristics (the purpose of the map). Any more than 6 or 7 and we start to struggle to distinguish unique colours on the map. Simple. Easily understood but...my don't people find these boring so how about we jazz it up a bit...
Here's another version, this time mashed up onto a topographic basemap.
Is it better?
I'd say no because a choropleth is its OWN basemap and by adding an underlay we add unnecessary visual clutter. Thematics are normally single-themed, so omitting detail that would make them harder to view is a core principle. Slapping it on top of a topographic map that obscures labels and other detail seems pointless. Labels are, in fact, cut off when they perhaps extend across water into the land area anyway. This adds nothing yet putting thematics over the top of topographic basemaps is a trend we see all the time because online basemaps are visible by default (they can normally be switched off).
But it gets worse...I've lately seen this type of choropleth...the blended choropleth.
Here for some reason, known only to the map author, the basemap and the thematic overlay have been blended together. The problem here is that by blending the two maps (or even using transparency for the thematic layer) you actually create a result that leads to significant problems for reading the map, seeing the patterns and understanding the distribution of the mapped theme.
Look at the following version without the water.
It's not now a choropleth. You just destroyed it. This map has, in fact, 44,271 colours. That's a few more than 6 or 7. It's impossible to identify areas of similar characteristics because they no longer exist. It's almost impossible to even see that there's a thematic overlay or that the theme is at country level.
If you really want to blend your choropleth with a basemap...pick something neutral so that there is a consistent canvas. Your colours will change and become a little duller (because you're adding grey) but they will be consistent across each area and will remain relative to one another visually. The following uses a grey basemap. You could argue internal water masses are a problem and you'd be right...but at least the map still functions at a basic level.
Blending choropleths with a basemap is a cart-oh-nono, particularly if you use a topographic basemap. You may think it looks cool, but it isn't. It makes the map that much harder to read and understand. Please don't do it.

A cacophony of cartography
Here's my Editorial from The Cartographic Journal Volume 51 Issue 1 for those that do not have access to the Journal itself (if not...why not...go take a look at a British Cartographic Society subscription and get The Journal for free!). Long read...
As 2013 turns into
2014 and we reflect on the state of cartography what do we know, what have we
learnt and what might the future hold?
Well, maps have
changed...quite profoundly and quite irreversibly. Maps are omnipresent; ubiquitous;
largely self-aggrandising; transient; personalised even. Many are single
purpose, single-themed and exist to exist because so many more people make them
now than they did 10 years ago. They are often used to demonstrate a technical
approach or a dataset rather than having a purpose beyond merely being made.
They too frequently come with quite disturbing bias and uncertainties which are
ignored by the author and unseen by the reader. The type of person that makes
maps now extends from the cartographic professional to data artists,
journalists and coders hacking together the latest data the internet has made
available. They map this, they map that, they move on. Is modern mapping showing
signs of autism, being characterised by repetitive behaviour? Certainly a lot
of contemporary mapping exhibits a serious lack of development of the
understanding of cognition and the language of cartography and many map-makers
repeat some basic mistakes that has professionals wincing. Or maybe modern
mapping is simply showing signs of immaturity as it seeks to emerge from a
fast-paced technological change that has characterised its recent development?
Maybe we're just seeing the reinvention of mapping in its tricky adolescent
stage and its struggle to overcome growing pains. The maps know they're always
right; they answer back; they're often rude to the point of arrogance and
disobedience but they'll grow up eventually; and all the time the parents hover
with sage advice that is rarely acknowledged. The professional cartographer vs
amateur map-maker debate rages on which is why I opened this Editorial
questioning where cartography is, yet have reverted to using the term mapping.
Mapping, to my mind, is what anyone can do. Cartography is what some of us do. A
lot of the former and not much of the latter made the headlines in 2013.
2013 also saw another
leap in map-making technology. The web is now becoming the publishing mechanism
of choice for many people because the barrier to use has reduced
dramatically. That’s created a demand
for mapping tools with most major players offering a web option for making
maps. Some are free. Some you can subscribe to. Some are packaged with other
licenses. As more data becomes freely available then the push for free
mapping tools continues and people are using them. Empowering indeed but I'd
wager this type of map-maker has never really looked upon a Coronelli globe, or
pawed a SwissTopo map sheet, or been amazed at a Berann panorama. For every one
inspired individual who has a magic touch and creates beautiful work there are
dozens of terrible maps. Map-making, then, is in rude health but it's a
cacophony of cartography...a harsh, often discordant mixture of the weird and
wonderful. Maps are everywhere but it’s worth repeating: a cartographic product
is a map that has been constructed professionally. A map-like product can be
made by anyone...a mapper, not a cartographer. That distinction has,
unfortunately, become somewhat irrelevant and I was recently invited to point
to great examples of cartography by providing a list of URLs. Well here's the
thing...not every map comes with a URL. It's fruitless pointing this out when a
list lives online because it simply ignores any map that doesn't have a URL.
URLs gives ease of access for so many but also causes a problem. People see
what they see online and that becomes their cartographic baseline such that
when they get round to making their own maps that's where they get their design
cues. This then perpetuates the idea that mapping begins and ends with
the internet and so we're developing a society whose standards and very belief
models are driven by online maps and mapping. This needs addressing because
there's a wealth of great work being ignored by the mapping masses because they
don’t know it exists. It’s revered by cartographers but unseen by map-makers.
It’s inevitable that
the cacophony will continue apace. As we move into 2014 and beyond our
technology will continue to improve and undoubtedly create new opportunities
for mapping but unless we strive to reveal better examples then people's
appreciation for quality will become harder to tackle. My hunch is that we'll
see more temporal maps as animation becomes easier to work with and more 3D as
browsers become more capable of handling the graphics. So much of the data we
can now work with has a temporal component or a third dimension so the search
for optimum ways of revealing meaning has to be at the fore of cartographic
work. We’ll also see more moves in the open source and open data
community and social media data will continue to be worked over as people
strive to make any kind of sense of it. Trouble is, as so many of today's maps
amply demonstrate, data is simply placed on a map, in a sequence and the viewer
is supposed to make sense of it and be amazed. They are...but for the wrong
reasons. They like the novelty but beyond that? Lots of data (often mistaken to
be 'big data') needs generalising and simplifying but rather than making sense
of lots of data by portraying salient aspects efficiently so they stand out,
maps will continue to strive to just show more and more as if more is always
better. Less, of course, often reveals more but in a cacophony, the loudest
maps often get heard the most above the general din.
As people who spend
their life immersed in maps, cartographers have a particular perspective on the
state of cartography as I'm sure most readers of The Cartographic Journal can relate to (that’s why you read
this!). We hear all the latest buzz about this map and that map but where is
this cacophony coming from? We're seeing the maps we're seeing because of one
thing...the public has an appetite for them which is driving another process
altogether. Where there is a demand, someone is always going to meet the demand
and there are numerous online forums, sites and commentators all clamouring for
a slice of the new golden age of cartographic pie. The demand at the moment
however is for quantity, not quality and the internet, not the discipline of
cartography, is reacting to that demand.
Take, for example, the
Facebook and Twitter pages of 'Amazing Maps'.
They have tens of thousands of followers...the sites exist simply to push maps
that are found on the internet to their followers. I'm one of them but for
every one that piques my interest and which I find genuinely intriguing, well
made and purposeful, there are dozens more that fail on a very basic
cartographic level. Often the maps display disturbing mistakes. I
see them. So do other experts. But many public do not...they are busy being
experts in their own field and simply see the map, consume it and move on.
The difficulty here is that there is a natural assumption that ‘Amazing
Maps’ (and other similar sites) are in some way curated by experts who are
undertaking a process of careful selection. They’re not and so we’re as likely
to get utter rubbish alongside a decent map. The apparent authority of the name
itself gives people a false baseline. Bad maps are bad for you simply because
you get the wrong message. It's a waste of calories. I'm all for quick
and dirty maps made well...but not ones that are constructed poorly. I
mentioned this myself on Twitter a while ago and someone said to me that yes,
they agree but while they like fine restaurants they also dive into Subway on
occasion. The food analogy is easy to relate to but I think it needs to
be more subtle here. Sure...go to a Gordon Ramsay restaurant and enjoy fine dining
(with expletives, obviously). Go to Subway and enjoy a sandwich too. Both
serve different 'qualities' of food and you would never expect a Subway to
serve up the quality that you know to expect from fine dining. However...would
you want to go into Subway and order a cheese and pickle sandwich that comes
with the cheese on the outside, trying desperately to envelop some bread with a
coating of pickle for good measure? At least Subway construct their sandwiches
according to the basic rules of sandwich construction so it works as a sandwich.
Bread on the outside, filling in the middle so it works (regardless of
its taste or nutritional quality). Discounting Heston Blumenthal, there are
very few chefs who take their ingredients and use them in ways no-one in their
right mind would conceive of yet still manage something that delights the
palette. Yet people are mashing up all
sorts of ingredients on maps and creating inedible fayre. That, for me, is the
problem with a lot of contemporary maps...they suffer from basic constructional
issues that really affects their performance as a map. If the public doesn’t
know the difference in the nutritional quality between a well constructed map
and a poor one then there is no hope of them knowing whether what they are
consuming is any good for them. The maps that get peddled on such sites are
being selected because they are pictures. Often you struggle to see what their
purpose actually is so in that sense they fail to function as a map because the
person who made them wasn’t particularly concerned about the qualities of a
map…they wanted a picture and a map seemed relevant. Their entire purpose is to
provide quick visual delight and nothing more so to do so they often break
fundamental cartographic rules. Some of our cartographic rules are there to be
challenged but some are there to maintain standards. If many of our new maps
ignore the rules they are simply ignoring what is good for them so they fail as
a map yet delight the curious who are just wanting a picture of something
vaguely interesting or entertaining. The appetite is there because the 88,000
(actually it's risen to 135,000 since I wrote this article) Twitter followers that @Amazing_Maps has dwarfs the combined
Twitter following of virtually all of my map expert friends combined. Just by
way of giving you a sense of scale I have 1300 Twitter followers, the British
Cartographic Society (@bcsweb) has 750, our President Peter Jones (@geomapnut)
has 66 (come on people…help him out!). Mapbox (@mapbox) has 16,000, Esri
(@esri) has 35,000, and my dog Wisley (@wisley_dog) has 9. You could make a
good argument that any in this latter list is more authoritative than ‘Amazing
Maps’ and you’d be right….but people go to ‘Amazing Maps’ and that’s what they
consume.
Tabloid newspapers
have higher circulations than quality broadsheets and this is what’s happening
to satisfy the public’s appetite for maps. No-one seems particularly bothered
who made the map and what their cartographic chops are.
The reporting is dubious but it sells. I would strongly argue that
being authoritative in your domain is crucial in distinguishing your work from
the masses but if the tabloids don’t particularly care it becomes a moot point.
It's therefore not the fault of the makers of map-making tools or the
map-makers themselves that we see so many poor maps. It's the consumers, where
they go to get their daily fix and the negative feedback loop this generates in
terms of informing their own work. Just like any service based on mass
consumption, if the demand is there, there will be someone keen to feed it
regardless of the quality. The demand is for maps, good, bad, big, small,
whatever...as long as I can click to see it and then click to see another. As
long as I don’t have to put in too much effort and it vaguely tantilises my
tastebuds (pass the salt). There are plenty of people and organisations that
have set themselves up in the last few years to satiate the demand purely to
serve their own agenda of being purveyors of content just like ‘Amazing Maps’.
How many of these have any real cartographic credibility? Take a look...you
won't find many publicly visible examples that have a strong cartographic
background. If we look at some of the most popular web sites who routinely ply
maps to the internet and check out their so-called best maps of 2013 we can see
the point illustrated.
Figure 1. Wired Maps
Run by two
self-admitted map novices, the Wired Maps blog has become an interesting
repository of the internet's offerings. Here they mix the contemporary with
historical curiosities with an eye on what went viral though claiming they were
all relevant in 2013 is odd when you look at some of the historical examples.
There's nothing in the title of the list that suggests 'great' in cartographic
terms yet the list is described as being that of 'great maps' and 'favourites'.
The question of greatness has to be measured against something though...page
hits? their own subjectivity? professional judgement? As with all the popular
lists, that's not entirely made clear so it is what it is...a list of maps that
piqued their interest. What I like about their list, however, is a mix of new
and old. It's not, like many others, confined simply to maps that you view
using a URL. There is a world of mapping beyond our glass interfaces that they
acknowledge which is good to see.
Figure 2. Fast Company
These maps are U.S.
focussed and specifically about how we look at the U.S. in terms of some
interesting themes...language, expenditure, tweeting etc. Purely thematic but
at least there's some coherence in the categories of maps that they have chosen
to explore. At least there's a focus to the list rather than a collection of
random curios. That said, this is possibly the weakest list in purely
cartographic terms. Some interesting data and themes but poor craftsmanship.
This is largely due to them being a range of thematic overlays mashed up on
basemaps that tend not to support the purpose. So we see the usual problems of
overprinted labels, Web Mercator defaults and thematic maps on top of
topographic basemaps. The language and twitter maps, in particular, go the heat
map route and Fast Company clearly go for maps with highly saturated colours.
Figure 3. Slate
A really rather
bizarre set of maps that range from the most basic push-pin overload efforts to
maps that support online quizzes to historical and heavily pictorial maps. The
one striking aspect of Slate's list is the variety of map they chose. They are
extremely inconsistent in cartographic terms which suggests that Slate are more
interested in the novelty value of the map rather than its inherent quality as
a map. We get Bob Dylan's world, a map of etymologies, maps of Starbuck's locations,
American folklore and 'This amazing map shows every person in America'. I love
this last one...labelling the map using the adjective 'amazing' in itself is
genius. The map wasn't actually titled that way...but Slate's own blog came up
with that blog title and so the amazing map was born. It is, of course, in
Mercator and mapping at the one dot = 1 person from aggregated census data plays
fast and loose with the ecological fallacy.
Figure 4. Gizmodo
A list heralded as
showcasing a 'banner year for beautiful, information-dense cartography'. The
maps actually illustrate Gizmodo's panchance for what might be termed boutique
mapping...where really obscure datasets are the interesting aspect and the map
has been used as a way of tapping into it. So we get maps of most popular
names, the age of every building in New York, internet connections, proximity
to pizza, where American's are moving, swimming pools in Los Angeles and the
rise of craft beer. It seems that if you can get your hands on some obscure
data that effectively writes its own headline, the map will instantly become
'liked'. You'd be hard pushed to get a professional cartographer to 'like' them
in terms of quality cartography though. In fact, a number contain some pretty
hideous errors in construction that have clearly gone unnoticed by the
majority. Is that a problem? Well yes...because it changes the message. A
banner year? Hmm...what these maps show is people can access really interesting
datasets fashion them into maps and give them a URL, some with innovative user
interfaces. This trend will continue in the short term at least.
Figure 5. The Atlantic
Titled as a
'favourites' list, actually The Atlantic's list of 7 maps is interesting
because it attempts to go beyond choosing maps based on novel or useful
information. Instead, it picks out maps it suggests 'we've never seen before'
due to their manipulation of time, dimensions, perspective and atmosphere. They
herald their picks as being 'innovative in design' and that they have set a new
bar for 2014. Maps are picked out for being cloudless, personalized, real-time,
animated, comparative, predictive, lots of dots or 3D. None of these are new
though. The fact they portray them as new simply shows they know little about
cartography and are ignoring that vast body of work that has gone before. So
these may be new to The Atlantic writers and are more than likely new to the
people that made the maps but let's have a little perspective here...just
because you aren't aware of prior art doesn't mean they are new. What The
Atlantic have done better than most, though, is showcase maps that are, for the
most part, well produced and they are certainly of a better quality as a
collection than many on the other lists. Interestingly, while the likes of
Mapbox and Google are trying to apply sensible cartography to produce better
products (generating cloudless imagery or generalizing content based on the
person viewing the map), for others the map is an opportunity to dump data.
Take the meta-map of OSM contributors for instance (Figure 5 bottom right).
What can you really see? Colour used to signify the more than 1 million OSM
contributors makes it meaningless. It's just a view of data but not a map.
Figure 6. GIS Lounge
A mixed bag here,
referred to as the 'most interesting and best maps of 2013' but which goes on to
admit that in fact the maps selected were based on those that seemed to
resonate most strongly with people and which produced the most public reaction.
Interesting approach...so the masses on the internet get to determine what is
'best' based on what has become most popular? In that case, make the list one
that simply showcases the 'most popular' rather than inferring that they are
therefore the best. Again...there's cartographic flaws abound and some of them
are quite serious. Does the fact Justin Bieber has such a great following make
his music any good? Does the fact McDonalds sell billions of burgers mean
they're nutritious? Of course not...and there's nothing wrong with those two
examples but no-one claims they are the 'best' of their genre. They sell. They
do it well. They are simply the most popular.
I would like to think
that the top 10 lists are not what we aspire to because let's be honest...
apart from a few examples that genuinely add to the canon we can do better as
cartographic history proves. Most of the maps are not innovative or new. Mostly
the lists are compiled by non-cartographers (non-experts) so it’s questionable
whether their view can be deemed authoritative in any sense. Some are simply regurgitating what's been most
viral during the year which is pretty lazy. How many have gone beyond their
keyboards and screens? How many saw the work on display at any number of
cartographic conferences this year? That answer is probably zero because none
of the lists above include any work that won any number of awards at
cartographic conferences during the year. Neither do these lists pay any
attention to commercial cartography, national mapping or any other major
cartographic activity. There is a vast wealth of cartographic riches that are
totally ignored because it’s not self-promoted and not available in a bite-size
format via a URL promoted by an irrelevant social media non-expert account. So
we have a situation where experts give kudos to one set of maps that are unseen
by the popular purveyors who give kudos to a completely different set of work.
There are only 5 maps
(out of 66) that appear on more than one of the lists I've reviewed here.
Of those, only two make it onto three lists: Ollie O'Brien's Bike Share
map and Joshua Katz's American Dialects map. I made my own 'favourites' list
this year and neither of those made the cut. In fact, 6 of the
11 I selected didn't appear on any of these other lists. So the winner
is...diversity. Perhaps in pure cartographic terms they all contain limitations
and we can pick them apart for what they don't do rather than what they do but
one thing's for sure...cartographic beauty is at least in part in the eye of
the beholder. And what of the concept of ‘quality’ anyway? Isn’t that in some
ways a subjective ideal? There is as much subjectivity in what we see as
'worthy' as there has ever been because cartography is part art. What works for
one person is not necessarily the same for another and that subjectivity is precisely
why there isn't more commonality across the lists and precisely why mapping is
such a diverse church. Even lists based on expert opinion fail to reach
consensus. The survey I did with Damien Demaj a while ago showed that
professional cartographers themselves have their own favourites and ideas of
what they feel is in their own personal top 10. This is to be expected because
cartography is as much about how we value aesthetics and our own perception of
quality. Some maps trigger an emotional response. To a cartographer, though,
many of the maps in the lists reviewed here simply don't make that connection.
They do not trigger that awe. To amateur map enthusiasts who are perhaps more
interested in the technical way a map was produced, or how the data was
manipulated, or the cool UI design...it creates the emotional response they
seek.
Therein lies one of the fundamental differences in the way I (and
other cartographers) might look upon a map. We're looking at the value of the
cartographic work. Cartography is the focus. To gain our respect it has to
achieve more than what most can produce; it has to speak to us, communicate,
and do it efficiently. But with most maps now being made by most people with so
few having the touch of a cartographer involved it's no surprise that so many
fail to get us so-called experts excited.
For most of the
examples above we can point to far more nuanced examples of the genre or the
technique. There's prior art for much of what we see today that is better
crafted. One's never going to be able to excite a public hungry for 'new'
examples by showing them something made 20 years ago if it doesn't come via a
URL...but how, then, do we encourage a public to develop a better sense of
quality, a better sense of cartographic taste? This is a huge question but in
an age where you'd hope that brain surgery was done by a qualified
neurosurgeon, your car service done by a qualified mechanic, your divorce
settlement handled by a qualified lawyer, your tax accounting handled by a
qualified accountant why is it that we accept maps that are handled by anyone
and everyone? There is such a thing as a profession of cartography; a body of
professional cartographers. It is these people who need to stand up, produce
great work and show the world that quality matters…otherwise the cacophony will
simply grow louder and more discordant.
There are other
impacts to the popularisation of map-making. It’s not just where people see
their mapping and take their design cues, it’s where they now seek the
knowledge to make their maps. I was
disappointed to read the preface of a textbook a couple of years ago which said
quite blatantly that the author was not schooled in cartography but because
they couldn’t find any books on the subject they felt it necessary to write
one. I was astonished since there are dozens, most of which were far more
useful and well written. All this illustrated was this particular author hadn’t
cared to look (the book wasn’t particularly good either). This phenomenon has
now transgressed onto the internet. There are some really well produced online
resources (e.g. The Geospatial Revolution videos and MOOC from Penn State
University) but there are also others that just leave me scratching my head.
While I’ll not point directly at a particular site (mostly because the author gets really quite uptight), very recently a new online
resource appeared to provide a ‘free introduction to geo’, GIS and cartography.
The author’s expertise is as a programmer. He has openly shown disdain for
cartography and its history, rules and prior art across social media. Yet here
he is, creating a slick online set of resources to ‘educate about mapping’.
Slick in the sense of it looks nice but you don’t have to dig very far to spot
the problems. It’s mostly utter nonsense and anyone with a vague knowledge of
geography, cartography, geo or GIS can blow holes in some of the gross
generalisations and misrepresentations. But then he pickes up nuggets here and there (usually after a period of Twitter related mud-slinging with people who know better) and then passes them off as if he's the expert. Yet it’s this sort of tabloid nonsense
that gets traffic. There’s no consistency to his work but people like it because
it isn’t challenging and they don't have to go far to find it; it makes making maps appear to be rather simple and
requiring minimal knowledge; it validates their own desire to see something as
quick and easy (and free); it justifies their belief that experts like making
things difficult to preserve their expertise; and that this new breed of
map-makers has somehow tapped into a magic that makes map-making trivial and
simple. This individual, with no cartographic background whatsoever who is now
professing to be a one-stop-shop for people who want to learn how to make
maps has nearly 3000 followers on Twitter (if you're following then you're spotting a pattern).
So we're awash with
tabloid reporting of tabloid mapping and tabloid style courses teaching people
how to make maps poorly. Mapping is mainstream and it's now news worthy for those that don't want to look very far or deep so we
digest a daily diet of this map and that map. Somewhere in the mix, though, the
rasion d'etre of cartography has gone awry. Making a map used to be all about
communicating something meaningful to a reader. The map itself is merely a
document that someone consults to learn something. It's a vehicle to take that
person along a particular route and guide them to a destination. The same is
true for maps that support navigation to maps that support the understanding of
global economics, or patterns of breast cancer or election results. But
tabloid reporting offers little or no critique and a map is 'liked' for the
mere fact it's a 'map'; a 'cool map' even. How many of the maps that appear in
these top 10 lists are described in terms of the meaning they impart, the analytical
task they support or the understanding they reveal? Not many. Most are in the
mix because they are simply 'maps'. There's little attempt to understand
whether they communicate their content efficiently, effectively or
meaningfully. They just map. Which brings me back to the point about
professionalism in cartography. The people selecting these lists are no more a
map expert than many who populate their lists. They’ve also now moved to make
web sites to tell people how to make maps. It’s a cartographic bypass. How is
it that they are able to assess relative quality in the maps they see or in the
statements they make? There's no real rigor to their process, no judgement made
by people who know the profession. To be fair there's nothing wrong with anyone
making a list of 'favourites' but where's the domain knowledge? Making a good
map needs two essential drivers: domain knowledge of cartography and domain
knowledge of the theme being mapped. Teaching about cartography needs more than
domain knowledge; it needs evidence of practice, engagement in the cartographic
community and also the ability to develop materials that are well researched,
rigorous and based on an understanding of pedagogy. Maps made by coders whose
domain knowledge is coding and doing fantastic things with data does not
necessarily make a great map. Their main goal, I would suggest, is challenging
themselves to do something innovative with the data and to make something that
simply looks cool. Do they really have the intent to communicate something
about the data or is it simply just mapping of the data? We see this so
often...an interesting data set mapped poorly which, in the hands of a
professional cartographer (or even a semi-skilled non-professional) and someone
seeking to understand something about the data could reveal something so much
more. Likewise when they turn their attention to trying to educate the rest of
us about cartography. I prefer my education to come from people who know what
they’re on about and I would like cartographers to use 2014 as the beginning of
a drive to reclaim cartography.
I would like to see
2014 belong not to the new map-makers and their lists and courses but to the
map-consumers who find more appropriate ways to get excited about maps and
learn about how they are made. I'd like to see a public whose appetite
for maps is matched by one that demands better quality and who are better
informed about where to seek advice on making great maps. I would like to
think that over time, this might emerge as more people tire of the cacophony
and, instead, seek the few examples of great work that are truly engaging and
well crafted. Is this even a possibility or are we beyond that point already?
My sense is the latter is the default for a while yet but it doesn't stop
me from some altruistic goal and a call to arms. The cacophony is simply too
deafening at the moment. It's beholden on makers of maps to learn a bit about
mapping so their work is at least based on basic tenets. It's also necessary to
improve the diet that consumers are gorging upon to improve their appreciation
for something that tastes better and to give them better materials to educate
them. We, the so-called experts, retreat to our cartographic societies, our
clubs and our friends who share the same concerns and see the world of mapping
through similar glasses. We hope for a future where more people have the sense
to pause before 'liking' but we rarely put our heads above the parapet.
So what's to be done
as we move into 2014 and beyond? In addition to continually striving to improve
the quality in The Journal and its
international scope and presence, colleagues in the ICA Map Design Commission
and I have pledged to write a daily blog during 2014 to showcase the very
best in classic and contemporary cartography (see
www.mapdesign.icaci.org). The intent is to build a repository of 365 maps
that cover the breadth of cartographic practice to illustrate, explain and
emphasize the importance of map design and to give URLs to quality maps. We
believe there is no other similar repository and instead of fighting the
internet and the tabloid mapping we see, we’re using it. It’s the
equivalent of introducing a new quality publication. By the end of the year we
will have created a compendium that can act as a reference for high quality
cartography. Some of the maps you’ll have seen before…some possibly not.
We’ll include both traditional print cartography and the very best that the
internet has to offer. Each map will be illustrated and accompanied by a brief
comment or two on why we feel the map exhibits great design. Hopefully the
maps we’ll showcase will provide a barometer for modern map making, inspiration
for those who seek ideas for how to map their data and also to improve the
public’s appreciation of and demand for quality in maps. We need people to
promote the repository so please do look and share the links amongst your
networks. BCS has done well over the past few years with the excellent Better
Mapping series and the Restless Earth Schools programme but as a community of
cartographers we need to engage with the vast number of online mappers and make
a stronger statement. Quite simply, we’re only scratching the surface along
with similar cartographic societies the world over. The cartographic profession
more generally has to step up to provide better examples of mapping and in
places that are visible to modern consumers. We also have to develop our
outreach as a profession and become more friendly, inclusive and engaging. It’s
going to take more than one or two people or web sites. It needs a concerted
effort by all those who consider themselves cartographers not just to sit and
moan about maps they see online but to do something about it. We need to turn
the tide and reclaim mapping.
