globalmapper.CalcAreaElevStats

globalmapper.CalcAreaElevStats([GM_LayerHandle_t32] aLayerList, GM_Point_t aPointList, float aXSpacing, float aYSpacing, int aReserved) → GM_Error_t32, GM_AreaElevStats_t[source]

Calculates elevation statistics from loaded elevation data within a provided bounding polygon at a provided spacing.

Parameters

  • aLayerList ([GM_LayerHandle_t32]) – List of layers to use or None for all

  • aPointList (GM_Point_t) – List of points in area in global coordinate system

  • aXSpacing (float) – Sample spacing in the x direction in global units (use 0.0 to get a good default)

  • aYSpacing (float) – Sample spacing in the y direction in global units (use 0.0 to get a good default)

  • aReserved (int) – Reserved for future use; must be 0.
