[mkgmap-dev] DEM/Contourlines causing grey (empty) squares at the border of maps

Fri Apr 27 06:40:56 BST 2018

Hi Felix,

hmm, yes, that really looks bad. At the moment I only have work-arounds:
1) Add additional DEM layers so that the error only shows up in smaller rectangles.
2) Don't use --dem-poly, I think this causes the trouble. Or maybe try the poly file created for the normal tiles.

I guess that the encoder still doesn't work 100% correctly, but I have no idea how to fix that and Frank Stinner seems to have stopped his work on

Hi Felix,

I'll have a closer look tomorrow. IIRC this also happens with Garmin maps.

well maybe it's more common - like in 1/5 maps if the include 1" DEM data - only happens if map includes DEM.

In some cases at the borders of maps - there appear grey rectangles in Basecamp and Mapsource (well do not mind Mapsource much - it's very outdated) - this only appears if using a DEM/contourline overview...

Sorry as Basecamp is windows only - only windows installer/Mac OSX gmap file here:
https://openmtbmap.org/mtbbayern.exe
or
https://openmtbmap.org/mtbbayern_macosx.7z

Without contourlines the map works fine (mapsetx.tdb...)
Contourlines map alone also does not work (mapsetz.tdb...)

So the bug is clearly in the transparent DEM/contourlines map. Sometimes simply rendering the contourlines map again and the bug is gone...

Seems to be not that common but also not that rare (maybe in 1 out of 20 maps)
