Reader Geoff Livingston sends word of an unusually elaborate Google Maps mashup in the works from geospatial developer FortiusOne that allows you to compare two locations as to the density of an arbitrary data set, if I’m understanding things correctly. The mashup uses Fortius’s GeoIQ API, which allows the visualization of a user’s data set in Google Maps, and displays two locations side by side. Clicking spots on the maps gives you a numerical rating of the data at the chosen points. In the image above, a data set representing traffic delays in San Francisco and Los Angeles are compared side by side. Very nice stuff. “In the app you can do this with any data set or mash up multiple data sets to solve a variety of problems surround location decisions,” reads the blog entry describing the mashup. Nice to see someone squeeze another level of usefulness out of Google’s mapping app.
