Heatmaps

Another best practice way to display data on a map using GISCARTA.
This style is applicable to point layers and allows you to configure the display as a heatmap.
When configuring this style, you can choose a numeric attribute for the degree of change for the point color intensity. If an attribute is not selected, then all points are set to the same intensity and a heatmap is created based on the point density distribution. If an attribute is selected, each point will be weighted by the attribute’s value. A point weight can vary from 0 to 1. If the value is greater than 1, then the point weight is set to 1. If the value is less than 0, then the point weight is set to 0. Therefore, an attribute with a weighted value between 0 and 1 is needed in order to get correct results.
User can also change:
  • gradient palettes
  • point radius
  • blurring
Heatmaps can be used in almost all areas of activity, such as:
  • Environmental studies
  • Transport Analysis
  • Mining
  • Urban Planning
  • Construction
  • Student studies
  • Geology
