Re: [sumo-user] Problem with converting shapefiles.

[cchadj01@xxxxxxxxxxxx]

Hello,

 Thank you really much for your answers!
 Using  Jacob Erdman's workarround I was able to solve my problem and  
it's good enough for now. I tried --shapefile.guess-projection and not  
much change and jakob's workaround
 still work.
 Now my network is converted to net.xml and can be opened in netedit.  
The problem now is that my network is not converted right and some  
parts (edges) are missing.
 Attached you can find an image that shows a sample of the problem.  
On the left my network is opened on netedit and on the left how it is  
should look like (opened the shapefile
 in QGIS). I can  not fix the road network manually because my road  
network is too big and would take a very long time.

Thank you,
Tom

P.S what would be the best way to populate my network to create a  
simple random simulation?
