Mobile Devices Need Custom Maps

GPS maps for smartphones generally require a fairly high-speed wireless internet connection, consume significant processor resources, and are optimized for driving. But what if your 3G connection is unreliable or unavailable, and you still need to get from point A to point B ? perhaps on foot?
Last week, I spoke with Eric Gunderson and Ian Cairns at Development Seed, one of the companies developing tools to create custom maps that work in a wider variety of situations, like this one. It?s not that farfetched: In a natural disaster and in the developing world, mobile phones may be useful navigational aids, but only if they can work without a reliable data connection and are optimized for different kinds of transportation than just zooming down the highway to the nearest Starbucks.
Development Seed caught our attention with a post that Cairns wrote for PBS?s MediaShift Idea Lab on custom maps for cyclists and drunken, late-night pedestrians. For StumbleSafely, DC Bikes, and DC Nightvision, a typical street map was overlaid with crime data, bike lanes, bar and bike shop locations, and municipal infrastructure: ?Not just buildings and roads, but even crosswalks, medians, and topography lines.? In short, all of the data that actually helps you get where you?re going when you?re not in a car.
These maps were built with TileMill, an open-source program the company created to help governments, NGOs, news organizations, and others easily create custom maps. The idea is to make map image tiles and Geographic Information System (GIS) data as easy to work with as RSS feeds or CSV databases are today.
?We want to put these tools in the hands of the subject-matter experts and see what they can do,? Gunderson told Wired.com. Development Seed won a Knight News Challenge award for the project.

One of the most-needed and currently most-poorly-served markets for mapping and data visualization support is in international development. As Gadget Lab reported this week, mobile devices are thriving in Afghanistan and elsewhere in the developing world, but data bandwidth and easy-to-find electricity aren?t.
?You can?t get an application like Google Earth working in Afghanistan,? Gunderson said. Maps On A Stick offers full-fledged, data-and-image-rich maps on a USB drive for no-bandwidth or poor-bandwidth use. The company and clients have plenty of experience with those scenarios, mapping uncharted road data in Africa, or helping relief workers provide housing assistance after Hurricane Katrina.
I think about those disaster scenarios often, just as I think about the people I love walking home alone in the city late at night.
When Apple launched the iPhone, it made a big deal about how its software team had written its own Maps client, using Google?s data only for the backend. It had to work for the touch interface, but it also had to make sense for how people would be likely to use Maps on a mobile device.
Now that easy mobile maps have become a natural part of our smartphone-carrying, 3G-surfing lives, it may be time for us to broaden our assumptions about the kinds of maps we?ll need and the conditions we?ll have when we need them.
