globalmapper.AreProjectionsEquivalent(GM_Projection_t aProj1, GM_Projection_t aProj2) → GM_Error_t32, bool[source]

Determines if 2 projections represent the same coordinate system. This is smart enough to treat projections like a particular UTM zone as equivalent to its base Transverse Mercator projection with the right parameters.

Parameters:

aProj1 (GM_Projection_t) – First projection to check
aProj2 (GM_Projection_t) – Second projection to check

Returns:

Error Code

Return type:

GM_Error_t32

Returns:

Are they the same?

Return type:

bool
