Hi Gerd, I have prepared patch according to these guessed rules. It rounds dem-dist and shift coordinates of top-left corner of DEM areas. Since dem-dist doesn't correspond exactly to HGT, interpolation is always active. I think there could be 2 ways to improve DEM quality. Interpolation could be changed to bicubic or mkgmap could use preprocessed data with correct pixel size. In the latter case probably data format other than HGT should be used. -- Best regards, Andrzej
