Hi,Gerd has published formula for his parameters, you have to multiply your dlon by 2^32/360. Value dlon=0.00027761 is equivalent of about x-dem-dists=3313.
Basically 1" arc DEM ~ 3314, 3" arc DEM ~ 9942. Or so I hope, I haven't tested. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
