Paul Bradshaw posted some thoughts yesterday on the
use of maps on news websites, a subject often discussed
on this blog.
Most recent 'highlights' are discussed such as
MPs expenses, although
Mapumental from MySociety is not listed, nor is my favourite longstanding example of a local news map, the
London SE1 News Map.
There is a good list of the advantages in using maps:
- They provide an easy way to grasp a story at a glance
- They allow users to drill down to relevant information local to them very quickly
- Maps can be created very easily, and added to relatively easily by non-journalists
- Maps draw on structured data, making them a very useful way to present data such as schools tables, crime statistics or petrol prices
- They can be automated, updating in response to real-time information
However, the post doesn't really get stuck into the difficulties and disadvantages of this approach. I've outlined a couple of points below which I believe are major barriers to a successful map-based news website.
User Experience / UsabilityUser research suggests that most of the audience still see a map as a route-finding device, a answer to "show me how to get from A to B" or "tell me where this building is", whereas news has long been consumed in a linear fashion, "Give me the big story of the day, what's the second most important item, and so on".
Mapping functionality is also quite complicated for a lot of web users and you cannot rely on the audience easily understanding how to pan, zoom, scroll a map, or cope with the differences in graphical pin-points, hover panels, embedded audio/video content.
Web users generally want to get at information quickly, particularly time-sensitive journalism content, and any design or interface barriers that prevent this can be quite a turn-off.
Geo-tagging or "Where do i put this story?"It would be simply fantastic to be able to assign a
latitude/longitude tag to every piece of content we create so that it can appear at the correct location on a map.
The reality is that this is simply not possible and even if it were possible, further difficulties emerge.
For example, imagine a bunch of stories appearing this week on transfer deadline day relating to one football club making several new player signings, whilst also being in the news for other financial or business reasons. We can easily tag all stories with the lat/long relating to the football club's home stadium, but how do users easily find and navigate between a cluster of stories located at the same point on the map?
Often there is more than one relevant location that can be associated with a news story.
For example, a person from location A, in partnership with another person from location B, is arrested for an armed robbery in location C, and the forthcoming trial will take place at location D.
Can we
geo-tag this story with all relevant locations? Does the technology understand the difference between each location? Does it matter?
Importantly, whatever the technology or editorial strategy delivers, how do we communicate this to our audience within the mapping interface? An interface which is already quite complicated and overcrowded with the standard set of mapping tools, place labels, and options for different graphical layers.
Then we have the regional story.
For example, House prices in Devon have fallen by X.
Devon is generally not a point on a map (it might be if the map displayed all of Europe in a small enough image size on screen and it was not possible to zoom in!) and yet we have a potentially important news story that needs to be
geo-tagged.
Postcodes introduce a similar problem as they are also polygonal areas rather than specific points. Tagging content with postcode does not provide a dot on the map for that content to be assigned to, it provides a region boundary similar to county, borough, electoral ward, and the many other areas of this type.
News stories can relate to other shape patterns. A news story about a river or a train journey needs a line on the map.
Some of these examples can be solved by providing a single point approximation to represent the story, although this can also be dangerous.
The
BNP membership map from 2008 provided several lessons in this area. At one point, whilst trying not to pinpoint exact houses, postcodes where used to make the information less specific. Unfortunately the mapping tool, in trying to be clever with the data, plotted the information at a specific point in the centre of the postcode, thereby seeming to be an accurate house-by-house set of data - but unfortunately pointing at all the wrong points on the map.
What's the big story?As I mentioned under the usability heading above, audiences have become very familiar with consuming news in a certain way that is very different to the map based approach.
A map is perfect for showing me something that is happening near to me, especially if it's a story that wouldn't normally make the top headlines, but I still want someone to tell me the big news, even if it is a little further away.
And that, I think, is the key target right now. Not simply solving these challenges and aiming to get as much of our content as possible onto a map, but finding the right way to include mapping as part of the consumption of news content.
Speaking at
Where2.0 in 2008 Adrian Holovaty stated that '
One question i like to ask myself is, would my site succeed without maps?'.
It's a very good question to keep asking.
