[Qgis-user] qgis browser hangs while opening big shapefile

Tue Aug 30 07:22:00 PDT 2016

Tyler;

I tried to clip without adding to the project.
It took about 20 seconds to complete. When I opened the resulting shapefile it was empty.
The algorithm gave a warning that the two shapefiles were in a different CRS. So maybe this is the problem. I will try to put them in the same CRS.

Reginald;
I am on 2.14.5 (thought I had also installed 2.16.x but I guess I skipped it). The first thing I noticed is when opening the file my memory usage doubled and qgis-ltr-bin.exe moved right to the top of the processes list. I didn't get any hang-ups but I feel I may have gotten close. Did you try using the clip function without adding the layers to the project? My machine did the clip faster and the result didn't not come in sluggish and I clipped it by about 1/3.

Reginald;
There are 2 download options, I would like to test the one you downloaded.
Which one did you download, latest of latest free?

Hi Tyler,

The shape can be downloaded from this link:

Hi,

I downloaded the latest shapefile of OSM for Belgium.
When I open QGIS browser and point to the buildings.shp (size : 325959kB) the application hangs, so I can’t change the CRM.
I also tried clipping the buildings.shp with a polygon shape of a town but that resulted in the same unresponsive behavior.
I’m using QGIS 2.16.1.
