Global Mapper Pro

Mismatch raster and area

I have a satellite image fragment(EPSG 3785) and its bounding area(EPSG 4326). I need to crop a raster to a polygon. When Enable GeoCalc Projection Mode, i get a large raster and polygon mismatch.
If this mode is disabled, then everything is fine.
What could be the problem?

    That sounds like it might be a bug. I suggest that you contact Blue Marble Support directly via email ( to report this. Please include a detailed description of your workflow, and sample data (image and bounding rectangle) that can be used to reproduce the problem. Thank you.

  • Hello, bmg_bob
    Problem solved, but another question arose: а similar effect occurs only if the raster refers to "Popular Visualisation CRS/Mercator"IEPSG 3785). In other coordinate systems everything is ok. 
    Many thanks!
