I was trying to make a nice looking print map of Bali (Indonesia) in TileMill. After creating a terrain layer (using this walkthrough) I noticed that the island's coastline was precipitous.
Is this caused by GDAL or wrong input data from CIGAR? I believe it can't be fixed within TileMill as the hillshading layer seems also affected.
Edit: With a bit CartoCSS the contour lines can easily be hidden. But not the slope scale image...
