Heat maps show the density of points in an area as a raster. Heatmaps are used to visualize distributions of dense point data and to show locations where a higher frequency of activity occurs.
Heatmaps are used to visualize distributions of point data and to show locations where a higher frequency of activity occurs.
Heatmaps help you quickly identify such areas – for example, a higher than the average number of criminal activities or traffic accidents.
Heatmaps are particularly popular for crime prevention planning by law enforcement agencies. These agencies use Heatmap to identify clusters of higher criminal activities and intelligently mobilize their resources to areas of high crimes.
A color gradient is used to indicate areas of increasingly higher density. Areas with sparse distributions are shown in a light color, and areas with no colors indicate places that don't have points.
What does a Heatmap show?
Heatmaps can be helpful in the decision-making process because they can show the following:
- Areas where many points are located
- Areas where high and low values for a particular attribute are clustered
Heatmap Methods
MapInfo Pro Advanced provides five different Heatmap methods. The first four methods use streamlined and simple workflows to generate standard Heatmap products that are suitable for most applications. The fifth method, Advanced, provides you with access to all the advanced features of the Heatmap tool.
