Heatmap layers describe the intensity of data at geographical points through a colored overlap. The intensity can be weighted by a numerical field.

Settings

The following sections detail every setting for the Heatmap Layer.

Basic

Core settings for the Heatmap Layer.

Setting	Description
Layer Type	Must be Heatmap to display the Heatmap Layer.
Dataset	The dataset to use for the Heatmap Layer.
Columns	Select a latitude and longitude.

Color settings for the heatmap.

Setting	Description
Color Palette	The color palette of the layer.
Opacity	The opacity of the heatmap layer.

The radius/coverage of the heatmap layer.

Setting	Description
Radius	The radius of the heatmap.

Weight settings for the heatmap. Weighing by a column increases the intensity of the map for points with the specified attribute.

Setting	Description
Weight Based On	A column to base the weight on.

General heatmap settings.

Setting	Description
Intensity	Value that multiplied with the total weight at a pixel t obtain the final weight. A value larger than 1 biases the output color toward the higher end of the spectrum, while a value less than 1 biases the output toward the lower end of te spectrum.
Threshold	A larger threshold smoothens the boundaries of color blobs while making pixels with low weight harder to spot.
