Hi David,

did you try r4126 without dem-poly?

Betreff: Re: [mkgmap-dev] DEM test & artifacts

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
