- globalmapper.CalcDistance(float aFromX, float aFromY, float aToX, float aToY, bool aLatLon) GM_Error_t32, float[source]
Calculates the great-circle distance in meters between two points. The points can either be specified as lat/lon values or in the current projection.
- Parameters:
aFromX (float) – start X/longitude coordinate
aFromY (float) – start Y/latitude coordinate
aToX (float) – stop X/longitude coordinate
aToY (float) – stop Y/latitude coordinate
aLatLon (bool) – TRUE - coordinates are lat/lon, FALSE - coordinates are in the current projection
- Returns:
Error Code
- Return type:
GM_Error_t32
- Returns:
Distance in meters between the points
- Return type:
float
Example
The following is an example of CalcDistance.
