Re: [mkgmap-dev] DEM/Contourlines causing grey (empty) squares at the border of maps
actually using the area.poly created by mkgmap splitting the switzerland.osm.pbf by geofabrik did work (the resulting map is much bigger then however) - so the poly file does seem to have something to do with it.... On 30 April 2018 at 19:09, Felix Hartmann <extremecarver@gmail.com> wrote:

die besten Daten sind IMHO derzeit: http://data. opendataportal.at/dataset/dtm-germany Aber die sind nur sehr begrenzt verfügbar.

scheint mir irgendwie auf die alten SRTM1v2.0 Daten Zugriff zu haben, oder irre ich mich und es ist die v3.0??

Ich habe ALLE .hgt getestet auf "void", "tooLow", "tooHigh", und fehlerhafte Werte auf Basis der Nachbarwerte korrigiert.
Beispiel für den Alpenraum:

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 <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).

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 <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.

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

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

Hi Felix, typically it depends on tile boundaries , poly file and dem-dists. In some cases a combination seems to require a special encoding which is not yet known. Also the transparent option might be special. Anyhow, I don't have much time to look at it for the rest of the week, and I have no idea how to fix it.

okay - well thanks for your reply. I also think now it mainly depends on the .poly file - however it can be that changing the dem-dist or the hgt imput files makes it work nonetheless (but not very likely) I think right now the best is to first try with the geofabrik poly file, if that does not work then use the area.poly file from mkgmap splitter after splitting the geofabrik extract. Except for the Europe map where I actually found breakage in the middle of the map - so far I've only found the error on the outside. The breakage in the Europe map made me believe it's not the poly`- but I think I got carried away because of this. Need more time to rerender every broken contourline map and check. The area.poly file produced by the splitter seems to work all the time - all my problem cases so far disappeared. I have one more idea - Could it be possible that the polygon is not allowed to be too complex? Maybe if within a tile there is a certain limit on how many times the area.polygon may cut in? In general all poly files that are not very complex work very well. What did actually work sometimes what splitting the tiles smaller, and then the map would work with all else equal. In general most countries with problems have very detailed area.poly file from geofabrik. Felix On 30 April 2018 at 21:39, Gerd Petermann <gpetermann_muenchen@hotmail.com> wrote:

actually using the area.poly created by mkgmap splitting the switzerland.osm.pbf by geofabrik did work (the resulting map is much bigger then however) - so the poly file does seem to have something to do with it....

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).

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 <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.

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

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

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).

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 <https://en.wikipedia.org/wiki/Concave_polygon>
And yes, I can confirm the missing altitude values with gray squares.
Gerd

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.

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

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

I also think now it mainly depends on the .poly file - however it can be that changing the dem-dist or the hgt imput files makes it work nonetheless (but not very likely) I think right now the best is to first try with the geofabrik poly file, if that does not work then use the area.poly file from mkgmap splitter after splitting the geofabrik extract. Except for the Europe map where I actually found breakage in the middle of the map - so far I've only found the error on the outside. The breakage in the Europe map made me believe it's not the poly`- but I think I got carried away because of this. Need more time to rerender every broken contourline map and check. The area.poly file produced by the splitter seems to work all the time - all my problem cases so far disappeared. I have one more idea - Could it be possible that the polygon is not allowed to be too complex? Maybe if within a tile there is a certain limit on how many times the area.polygon may cut in? In general all poly files that are not very complex work very well. What did actually work sometimes what splitting the tiles smaller, and then the map would work with all else equal. In general most countries with problems have very detailed area.poly file from geofabrik.

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