From the Mapstraction site:
Users can switch maps as desired based on personal taste and quality of maps in their local area. Various tools built on top of Mapstraction allow users to easily integrate maps into their own sites, and configure them with different controls, styles, and provider.
I plan to discuss Mapstraction more over the next few posts. With Google’s recent change to their API Terms, many are switching from the Google Maps API and Mapstraction will undoubtably play a role in some users’ transition schemes.
R. Buckminster Fuller was truly a modern Renaissance Man. Bucky created many inventions and championed several ideas that have shaped the way we live. One of his creations is the Dymaxion map projection. The map projection is rather complex; the developable surface is an icosahedron. When the icosahedron is then sliced and flattened, it produces a world map that is visually intriguing. It is truly unlike any other map projection.
In Zachary’s post, he also mentions the Faumaxion web map, which is a Flash-based web map that reorients itself so that north is at the top for any of the triangular faces of the Dymaxion projection. Michal Migurski, a partner at Stamen Design, has the details on how he created the Dymaxion slippy map.
The downside to using a Dymaxion projection in your web map is that the support for the projection amongst the mapping APIs is minimal. You will need to do more of the heavy lifting in order to get this projection working properly in your web map. That’s also ignoring the fact that many people are not spatially aware and that this different projection will require your audience to orient themselves with the way the Earth has been projected. While Spherical Mercator is common and familiar, it does grossly exaggerate the areas closer to the poles, which in turn distorts your mapped data. Choropleth maps depicting a variable dependent on area, such as population density, are often misleading when mapped with a Mercator projection. The Dymaxion map is closer to an equal-area map than most, however the variable orientation towards North makes this projection a hard sell to a general audience.
Nonetheless, the Dymaxion map is an incredible map projection, from both a scientific and aesthetic point of view. The time spent by some very dedicated, intelligent people to get this working in interactive form speaks to the admiration of the projection and its creator. If only Bucky had lived long enough to see what wonders the Internet hath brought…
If you have no experience with web mapping, but have some basic website-building experience, you can begin to make interactive web maps fairly easily using Google’s mapping application programming interfaces (APIs).
The University of North Carolina has developed an awesome way to explore historic photographs and maps of the Blue Ridge Parkway. Driving Through Time features two web maps that serve as the primary means of exploring their digital catalog of photographs and scanned paper maps.
Driving Through Time is a great example of making information accessible using web maps. These documents have likely been with the UNC Library system or the State of North Carolina for years, unseen by the public because they existed only as hard copies. Now that they are available through a web map, you can explore the history of the Blue Ridge Parkway from anywhere in the world.
Welcome! I am developing LearnWebMapping.com as a resource for you to find information about web mapping concepts, APIs, tips and tricks. I am also developing an online college course on web mapping, including a discussion of client-side mapping interfaces, GIS services, and best practices to help you build awesome map applications. You can find out more about the course offered through Rowan University Online at the About the Course link here and above.
Check back as I post articles and links to interesting web maps for inspiration and educational resources for guidance on your next project.
