Hallo Peter,Eher würden mich die Copernicus Daten der EU interessieren - hier bin ich aber noch nicht richtig dahintergekommen wie ich die konvertieren soll.Also die hier: https://www.eea.europa.eu/data-and-maps/data/ copernicus-land-monitoring- service-eu-dem Oder sind dass genau jene die du mit OpenDEM meinst?die besten Daten sind IMHO derzeit: http://data.opendataportal.at/dataset/dtm- germany Aber die sind nur sehr begrenzt verfügbar.Die Quelle:scheint mir irgendwie auf die alten SRTM1v2.0 Daten Zugriff zu haben, oder irre ich mich und es ist die v3.0??On 30 April 2018 at 18:59, Peter Danninger <peter@danninger.eu> wrote:Servus Felix,

Ich habe ALLE .hgt getestet auf "void", "tooLow",

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.

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
<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).

(empty) squares at the border of maps
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.

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.

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

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)
