[mkgmap-dev] HGT - getElevation()

Hi Andrzej,

did not try the patch but I wonder why you don't use the modified area
for the hgtConverter as well?

Hi Gerd,

I have attempted to reduce interpolation, when DEM pixel size is the
same as HGT pixel. I have stretched a bit area of DEM, so edges are
aligned with HGT. I'm attaching a patch.

Resulting map looks similar, only shading has moved a bit. I'm not sure
if this is the result of differences in interpolation or maybe change
introduced by moving DEM borders.

Best regards,
