The second mapping resource is a service called PolicyMap. It only covers the US but does a very good job of layering multiple data sets on the NavTeq mapping API. The service breaks down the data in just about any way you might want to see it: By census tract, by zip code, by Congressional District, etc. It provides good leads for business and CI professionals and Law Enforcement Intel types looking at strategic issues. For example, if I wanted to focus a marketing campaign on the retiree communities in Erie, I might want to use the map below that shows aggregated retiree income by census tract in Erie (darker colors mean more retiree income). Its just a screenshot of part of the data, though; if you want the full map, you will have to go to PolicyMap.com as the service provides no embed feature.

Thanks for the link! I agree with the critique. When I first looked at Erie I was hoping for something more robust than what I got. Still, it is a step in the right direction and I suspect it will get more sophisticated over time. The price is right, too!

Kristen,
ReplyDeleteThanks for your kind words on PolicyMap! I just wanted to make a slight correction. The site is built on the Pushpin API. The underlying streets data is indeed provided by NAVTEQ.
Thanks again!!
My mistake and apologies!
ReplyDeleteThanks for the correction.
