In fact, you could also test the intersection against the BBOX of your polygon to make things a bit faster (that could be done even without a csv BBOX, just dealing with numbers). How to build a QgsRectangle is described here, if that's what you were looking for initially. | |
| Jul 13, 2020 at 14:32 | comment | added | DGIS | Thanks for the advice, I will try that. However, do we know anything about the time cost it takes to convert text to QgsVectorLayer objects? I was hoping to keep the text format to keep computation time as low as possible. | |
