DEM/Contourlines causing grey (empty) squares at the border of maps
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borders of maps - there appear grey rectangles in Basecamp and Mapsource (well do not mind Mapsource much - it's very outdated) - this only appears if using a DEM/contourline overview...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) -- Felix Hartman - Openmtbmap.org & VeloMap.org Schusterbergweg 32/8 6020 Innsbruck Austria - Österreich
well maybe it's more common - like in 1/5 maps if the include 1" DEM data - only happens if map includes DEM. On 26 April 2018 at 20:20, Felix Hartmann <extremecarver@gmail.com> wrote:

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 if the poly is a bit bigger - it would not happen? Could you try by enlarging the poly 2km to the outside? Not using a poly at all would be really big or am I wrong? Which normal poly do you mean? The area.poly created while splitting the geofabrik osm files? Or the area.poly created while splitting the phyghtmap osm.pbf contourlines file? I also noticed that while any of that grey square is visible in Basecamp - Basecamp does not show altitude in the lower left corner anymore.

Hi Felix, I think it is the shape of the poly that matters. Triangular shapes seem to be problematic. Pattern in DEM would be something like UUUUUUUUUUUUU UUUUUUVUUUUUU UUUUUVVUUUUUU UUUUVVVUUUUUU UUUVVVVVUUUUU with U for undefined and V for knwon height. If you use the (rectilinear) area.poly created by splitter when splitting the geofabrik OSM files you will not see this pattern as often. Maybe it would be enough to change the poly so that it is convex, not concave: https://en.wikipedia.org/wiki/Concave_polygon And yes, I can confirm the missing altitude values with gray squares.

Hi Gerd - can you find a pattern here? Folllowing are the polygons of 10 broken (out of a sample of 94 rather "small" countries) poly files. https://openmtbmap.orgbroken_contours.zip it's Germany, Bavaria, Czech, Finland, Niedersachsen, Nord-Rhein-Westfalen, Poland, Paraguay, Romania Switzerland, Sweden The remaining 84 countries work fine in Basecamp (leaves about 60 countries which are usually pretty big and I did not care to check as it means zooming in to 30km, sometimes 50km and pan around all borders of the map in Basecamp to spot if it's working or not).

I'm not fully sure it's because of the poly file - but it's clearly not based on wrong/broken input data. I created the Alps and Switzerland equally, and all of Switzerland is part of the Alps map too. Alps work, Switzerland does not. Strangely though changing the style-file a little - it may mean a map does not have the problem - so I think it's maybe only partly related to the poly file?

I think it is the shape of the poly that matters. Triangular shapes seem to be problematic. Pattern in DEM would be something like UUUUUUUUUUUUU UUUUUUVUUUUUU UUUUUVVUUUUUU UUUUVVVUUUUUU UUUVVVVVUUUUU with U for undefined and V for knwon height.
If you use the (rectilinear) area.poly created by splitter when splitting the geofabrik OSM files you will not see this pattern as often. Maybe it would be enough to change the poly so that it is convex, not concave: https://en.wikipedia.org/wiki/Concave_polygon
And yes, I can confirm the missing altitude values with gray squares.

I guess if the poly is a bit bigger - it would not happen? Could you try by enlarging the poly 2km to the outside? Not using a poly at all would be really big or am I wrong? Which normal poly do you mean? The area.poly created while splitting the geofabrik osm files? Or the area.poly created while splitting the phyghtmap osm.pbf contourlines file?
I also noticed that while any of that grey square is visible in Basecamp - Basecamp does not show altitude in the lower left corner anymore.

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 https://github.com/FSofTlpz/Garmin-DEM-Build

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.

But Europe continent map seems to be broken too... so it's not that simple... I really don't know why alps is working and switzerland broken. I'll try if the broken maps work if I exclude viewfinderpanoramas 1" data and only use 3" data. On 30 April 2018 at 15:22, Felix Hartmann <extremecarver@gmail.com> wrote:
I'm not fully sure it's because of the poly file - but it's clearly not based on wrong/broken input data. I created the Alps and Switzerland equally, and all of Switzerland is part of the Alps map too. Alps work, Switzerland does not. Strangely though changing the style-file a little - it may mean a map does not have the problem - so I think it's maybe only partly related to the poly file?

Hi Gerd - can you find a pattern here? Folllowing are the polygons of 10 broken (out of a sample of 94 rather "small" countries) poly files. https://openmtbmap.orgbroken_contours.zip
it's Germany, Bavaria, Czech, Finland, Niedersachsen, Nord-Rhein-Westfalen, Poland, Paraguay, Romania Switzerland, Sweden
The remaining 84 countries work fine in Basecamp (leaves about 60 countries which are usually pretty big and I did not care to check as it means zooming in to 30km, sometimes 50km and pan around all borders of the map in Basecamp to spot if it's working or not).
