Re: [sumo-user] Segmentation fault in netconvert with --heightmap.shapefiles
Thanks for the explanation. As it seems not to be an appropiate shapefile for the region I want to study, I have changed the approach of the problem and I'm trying with TIFF files and now it seems to work, at least the fcd and emission output files have a z-coordinate.
Thanks a lot!

The current heighmapper code expects a triangulated mesh of x,y,z coordinates when loading shape files. It cannot deal with elevation lines. Moreover, as far as i can tell, your dataset only includes the elevation lines without any actual z data so I don't think it's even possible to extract the needed information.

I've sent another reply to you with the attached files which is pendant of approval by the moderators. In the meanwhile, I've compiled SUMO with PROJ-6.1.1 and the same segmentation fault error emerge despite fixing the libproj.so warnings.

Yes, that warning could indicate the cause of the crash. If in doubt, provide input files so we can test your input with a clean built of netconvert.

Hello,

I'm having troubles to load shapefiles topography in order to assign elevations to my network. I've installed SUMO with all the requisites to load shapefiles (i.e. with GDAL dependencies). Now, I don't get a dependencies error but a simple "Segmentation fault", as shown in this example:

netconvert --osm-files Madrid.osm --output-file sumonetwork.net.xml --osm.stop-output.length 20 --ptstop-output ptstops.xml --ptline-output ptlines.xml --geometry.remove --roundabouts.guess --ramps.guess --junctions.join --tls.guess-signals --tls.discard-simple --tls.join  --heightmap.shapefiles /mnt/lustre/home/u7262/sumo_scripts/spacmaltimetria20m2000/SIGI_MA_ALTIMETRIA_20Line.shp

Segmentation fault

Without the --heightmap.shapefiles option, it works properly. Furthermore, I've noticed this warning while building SUMO. It could be related to my problem?

libproj.so.15, needed by /mnt/lustre/home/u7262/gdal-V1.10.0/lib/libgdal.so, may conflict with libproj.so.13

Thank you.

Best regards,
Alejandro
