Re: [sumo-user] proj.4 string in netconvert
|
Hi Sasan,
what I can tell is that the proj string is used in general. I changed the projection to a "wrong" UTM zone and could see the difference. Also netconvert transmits the whole proj string to the PROJ library which does the projection. However I am not sure how much coordinates would change with the ellipse you selected...?
Best regards
Mirko

Dear all,
I am trying to use a proj.4 string for my netconvert (version 1.18)
from OSM to SUMO but apparently it has no impact on the output. Is
this a bug or am I doing something wrong? I remember I have used it in
older versions of SUMO. This is how I use it:
netconvert --osm-files map.osm --proj "+proj=utm +zone=32 +ellps=GRS80
+towgs84=0,0,0,0,0,0,0 +units=m +no_defs" -o network.net.xml
Thanks,
Sasan
