Heatmap pages are now available for every Your Mapper dataset. This means you can see a snapsot of all a map’s data at once, showing you the density of locations, and letting you drill down to the details in that area.
The heatmap shows up to 1,600 colored blocks. Each block is clickable, and the popup shows you how many locations are within the block, and provides a link to an interactive map at that location with all the details.
Below each heatmap is a link so you can download the entire KMZ heatmap file for your own use, either in 3D Google Earth, Google Maps, Bing Maps, Yahoo Maps, or any other application that supports KML/KMZ files.
Anytime our datasets are updated, so are the heatmaps on our servers. The heatmaps cover the entire area covered by a dataset, and historically for all dates available.
There are also heatmap breakdowns for every category. Here are 6 category heatmaps for the New York City 311 Service Calls map:
We overcame the technical hurdles involved with heatmaps since we started working on them 3 months ago. And we improved the heatmap details in the overview pages which launched 2 months ago. We are still working on ways for you to create your own dynamic heatmaps for smaller areas of a dataset, with custom filters like multiple categories, date ranges, and keywords.
These heatmaps were added as a feature to the site specifically for the upcoming NYC BigApps competition. Public voting is coming in December, and we’ll keep you posted on how to help out!
