[mkgmap-dev] DEM test & artifacts

From David david.tlp at orange.fr on Wed Feb 21 18:32:45 GMT 2018

Hello Gerd,

Here is more information about how I obtained my result. I used mkgmap v4107 and  splitter v590. My options for DEM are :

dem=./MySrtm1Folder
dem-dists=3312,13248,26512,53024,106048
dem-poly=./MyPolygon.poly
dem-interpolation=auto
overview-dem-dist=212096

I do not define any polygon option for splitter. As explained in my previous email, to avoid the generation of a shadow in plain ocean, I defined a new polygon inside the correct shadow rendering area and it solved my problem. For the artifacts I described, follow this link to see what I mean : 

http://emerald-island.eu/wikka/ShadowArtifacts

It was made with mkgmap version 41067 and 4126 and splitter 590 with the same result.
	
Again for your great work, chapeau bas,

David
