[mkgmap-dev] Resolution 23 raster problems

Fri Apr 23 11:01:15 BST 2021

Any ideas why this is happening?
Some of the contourlines intersect each other at resolution 23 - I
especially used reduce-point-density=1.0 to try to stop it.

java -jar -Xmx47000M /home/contourlines/mkgmap.jar --keep-going
--dem-poly=/home/contourlines/bounds/bayern.poly
--series-name=openmtbmap-cntrs-DBY-23-Apr-2021
--dem=/home/contourlines/hgt/VIEW1/,/home/contourlines/hgt/SRTM1v3.0,/home/contourlines/hgt/VIEW3/,/home/contourlines/hgt/SRTM3v3.0/
--dem-dists=5520 --max-jobs=7 --reduce-point-density=1 --transparent
--style-file=srtm24 --latin1 95260000.osm.pbf

Is there any way to improve this?

Look at the screenshots - the small one is resolution 23, the big one 24.
If using 10m interval contourlines this is pretty obviously not ideal.
Resolution 24 could be nicer - but I guess this is more a problem of
phyghtmap (while groundtruth can produce higher quality), but resolution 23
really becomes confusing vs 24...:
