globalmapper.GenerateDensityGrid

globalmapper.GenerateDensityGrid(GM_LayerHandle_t32 aPointLayer, GM_DensityGridParams_t aGridParms) → GM_Error_t32, GM_LayerHandle_t32

Generates a density (heat) grid from the point features in a layer. The values will be based on either just the count of point features or the value of some attribute. The returned layer handle must be closed with CloseLayer when you are done with it.

Parameters:

• aPointLayer (GM_LayerHandle_t32) – Layer to get points from

• aGridParms (GM_DensityGridParams_t) – Parameters for generating density grid

Returns:

Error Code

Return type:

GM_Error_t32

Returns:

Created density grid layer

Return type:
