#718 closed defect (fixed)

QGIS crashes when I try to query large contour polygon ShapeFiles

Reported by: Bob.Bruce Owned by: nobody
Priority: major: does not work as expected Milestone:
Component: Vectors Version: 0.8.1
Keywords: Cc: lami@…
Must Fix for Release: No Platform: Windows
Platform Version: WIN XP SP2 Awaiting user input: no


QGIS doesn't handle this dataset very well. It seems to have difficulty classifying the polygons by the attribute MAXHEIGHT and as soon as I try querying a polygon it crashes every time. I have tried doing this with other software (in case there might be a problem with the data) and it works fine with the dataset. I am using QGIS 0.8 and 0.8.1 on a WIN XP SP2 system.

I will attempt to attach a ZIP file (of about 14Mb) to this ticket for you to use in duplicating this problem. I have several other datasets like this one if you want to try those as well.

I suppose that those shapefiles are 2.5D types (with a z-value for each vertex). Version 0.9 is supposed to handle those correctly. 0.8.1 is able to display them, but identify and vertex editing does not work. We should probably display a warning for 0.8.1 in such cases and prevent a crash.

Marco, you are right, these are 3D SHAPE files. I have uploaded the files that I was using to my webserver, you can access them at: this server is a bit slow, I tested the access from work and it took about 4 minutes to download the file.
