[mkgmap-dev] The "Elevation=M" in the header of the polish .MP files does not work

Thu Mar 2 13:38:27 GMT 2023

Hi 

Yes.

Types  0x23.0x24.0x25 are used to create bathymetric maps.

Information from the MPCTypes.txt file ( TypViewer application):

0x02000=Contour Lines/MINOR_CONTOUR/Minor land-based contour line/Non NT
0x02100=Contour Lines/INT_CONTOUR/Intermediate contour (should be used for about every 5th contour line)/Non NT
0x02200=Contour Lines/MAJOR_CONTOUR/Major contour (should be used for about every 10th contour line)/Non NT

0x02300=Contour Lines/MINOR_BATHY_CONTOUR/Minor bathymetric, or depth, contour/Non NT
0x02400=Contour Lines/INT_BATHY_CONTOUR/Intermediate bathymetric, or depth, contour (should be used for about every 5th contour line)/Non NT
0x02500=Contour Lines/MAJOR_BATHY_CONTOUR/Major bathymetric, or depth, contour (should be used for about every 10th contour line)/Non NT
