Heat map, a density visualization technique<\/a>, shows areas of high and low concentration on a map. While, a point map with 10’s of thousands of locations can become cluttered, a heat map visualization of the same data can quickly show areas of dense population.<\/p>\n\n\n\n For example, if you plot the locations of all your customers as a heat map, you can quickly see where there are pockets of low or high number of customers.<\/p>\n\n\n\n ZeeMaps provides support for a these maps in both the interactive and print versions. Currently, we look at the frequency, or number of points at a given location, to determine the density. Over time we’ll extend this to allow for the density value to be determined through one of the the marker fields. Here’s an example of a heat map of locations of all the Used Computer Stores in the US<\/a>. First, with the map, one can quickly see that Boston and New York are the most dense areas. While, other major cities like San Francisco, Dallas, etc., have some notable presence as well.<\/p>\n\n\n\n Now, click on the icon at the top right of the map. Notice, the display will change to the regular clustered point map.
Notice, you can combine this feature with the Zip Code Finder<\/a> tool in ZeeMaps. Finally, a great way to quickly determine the zip codes with high density of points on a map!<\/p>\n\n\n\nExample Map<\/h2>\n\n\n\n
