Using QGIS - I have two feature layers that look to be in alignment. Yet they do not share the same coordinate system. When I switch one layer to the same coordinate system so that they both match, they no longer align. I need them to share the same coordinate system so that I can Clip.

    Please read up on on the fly reprojection and be advised, that clip works usually flawlessly with data in different CRS. – Erik Feb 02 '23 at 14:29
  • I keep getting "Intersection failed" when trying to clip. Assumed it was the mismatch. – map_stuff_now37 Feb 02 '23 at 14:34

    To bring different layers to the same projection (CRS), you must reproject them: e.g. right-click layer > export and in the export settings, select the CRS you want to reproject to. For background, see https://gis.stackexchange.com/a/392388/88814 and https://gis.stackexchange.com/a/383437/88814 – Babel Feb 02 '23 at 14:35
  • I reprojected using the export method - this worked. But clip still failing with same error. – map_stuff_now37 Feb 02 '23 at 14:38

    Have you made sure their geometries are valid? Is at least one (the second) of your layers a polygon? – Erik Feb 02 '23 at 14:45
  • I ran 'check validity' and both feature layers have 0 errors, and 0 invalid. One is US counties. One is a large polygon. Trying to clip US counties to identify which are within the large polygon. – map_stuff_now37 Feb 02 '23 at 14:54
  • So probably sharing your data would be a good option. – Babel Feb 02 '23 at 15:02
  • Would be happy to share the zip folder with two feature layers...best method? – map_stuff_now37 Feb 02 '23 at 15:11
