Re: [sumo-user] Importing Elevation Data from GeoTiff: Error: Unknown co

[SchlenkPa <schlenker@xxxxxxxxxxxxxxxxxx>]

Hello,

The problem was solved by converting the CRS to EPSG:4326 - WGS 84 -
Geographic.
Thank you very much for the help.

location with the old CRS: <location netOffset="-292145.67,-5628783.83"
convBoundary="0.00,0.00,1540.99,1307.47"
origBoundary="6.051284,50.773657,6.073494,50.785355"
projParameter="+proj=utm +zone=32 +ellps=WGS84 +datum=WGS84 +units=m
+no_defs"/>

location with the new CRS: <location netOffset="-292145.67,-5628783.83"
convBoundary="0.00,0.00,1540.99,1307.47"
origBoundary="6.051284,50.773657,6.073494,50.785355"
projParameter="+proj=utm +zone=32 +ellps=WGS84 +datum=WGS84 +units=m
+no_defs"/>

So nothing changed there. But it works now and I get a 3D landscape in SUMO.

With best regards
Paul Schlenker
