Re: [sumo-user] Bologna scenario latitude longitude coordinates

The networks of the Bologna scenario at https://github.com/DLR-TS/sumo-scenarios/tree/master/bologna are geo-referenced. You can use the methods listed at

Hello,

I am working with the Bologna scenario from
https://sumo.dlr.de/docs/Data/Scenarios.html#bologna. I use the python
library sumolib.

I need to convert the XY coordinates of the nodes of the file
joined_buslanes.net.xml to latitude longitude.

The page https://sumo.dlr.de/docs/Networks/SUMO_Road_Networks.html says
that "For networks with no projection (projParameter='!'), only the
offset must be applied.", which is the case here.

For some node, getCoord() gives me (1865.21, 105.5). I also have
'netOffset="346.83,-207.06" convBoundary="0.00,0.00,2164.41,1916.16"
origBoundary="-346.83,0.00,1817.58,2148.55"'.

How do I get the lat lon coordinates from that?

Apparently there is a large roundabout in the dataset that is at
44.494554,11.314393 so the XY coords that I have should match something
close to that roundabout.

Best,
Antoine
