globalmapper.CalcEnclosedArea¶
- globalmapper.CalcEnclosedArea(GM_Point_t_array aPtList, int aNumPoints, GM_Projection_t aProj) GM_Error_t32, float [source]¶
Calculates the enclosed area of a region in square meters. The coordinates in aPtList are in the projection defined by aProj. If None is passed for aProj then the current global projection as returned by GetProjection is assumed.
- Parameters
aPtList (GM_Point_t_array) – list of points defining area
aNumPoints (int) – the size of aPtList
aProj (GM_Projection_t) – projection of points in list (use None for current projection returned by GetProjection)
- Returns
Error Code
- Return type
GM_Error_t32
- Returns
Enclosed area in square meters
- Return type
float
