I have been trying to perform a intersect (then tried using clip) on a rather large dataset on QGIS. I have been able to complete similar geoprocessing using slightly smaller datasets and the layer. For this layer no errors are being reported but the clip/intersect function seems to be unable to move past 28% complete (tried multiple times). Does anyone have any advice or help they can offer beyond trying to maximize my computers available processing capability?
Usually QGIS tends to look as if it's stopped processing or crashed ("Not responding" message) but is in actual fact still processing the data. You can check this via the Task Manager while running your intersect/clip function and see if qgis-bin.exe is using CPU usage. If it is then you may have to wait a while, particularly with chunky datasets.
Depending on the size of your dataset, it is common for processes to last hours if not days. There are ways to decrease processing time such as:
- Upgrading your CPU
- Adding more RAM to your Computer
- Delete unwanted fields/columns in your layers
Also thanks to @SAnderka who also mentioned that if QGIS crashes then there should be a "crash dump written" pop-up error message.
