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

Thu Mar 2 15:01:32 GMT 2023

Hi all,

OK, I see no problems to change this method  in GType.java:
        public static boolean isContourLine(MapLine line) {
                return line.getType() >= 0x20 && line.getType() <= 0x22 && !(line instanceof MapShape);
        }

All I have to do is to change 0x22 to 0x25, right?

Gerd

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

Hi

My understanding of the default Garmin usage is that
 0x20..0x22 are land/height contours (Minor to Major)
 0x23..0x25 are sea/depth " "
