Geospatial visualization is a fascinating field and we plan on covering it more here on GraphGraph. In my other moonlighting gig, I write for Geekadelphia, my first post was on Geotagging Philadelphia, based on the “Locals and Tourists” project that Eric Fischer put together.
I’m linking to it because I think Eric’s project is a fantastic example of real insight from mashing data with maps. I analyzed Philadelphia because it’s my home, so I encourage you to look at your city and see what information you can learn about where you live.
