- globalmapper.GenerateContours(GM_LayerHandle_t32 aLayer, GM_ContourParams_t aContourParms) GM_Error_t32, GM_LayerHandle_t32
-
Generates contours from loaded elevation data and creates a new vector layer with the results. The returned layer handle must be closed with CloseLayer when you are done with it.
The aContourParms parameter can accept the contour interval size in meters or in feet; if is provided in a different unit, it will be automatically converted into meters.
- Parameters:
-
aLayer (GM_LayerHandle_t32) – Layer to get elevations from or gm.NULL for topmost layer at each point
aContourParms (GM_ContourParams_t) – Parameters for generating contours
- Returns:
-
Error Code
- Return type:
-
GM_Error_t32
- Returns:
-
Created contour layer
- Return type:
-
GM_LayerHandle_t32
