I am trying to run a Iso-Area as Interpolation (from Point) calculation using QNEAT3 in QGIS 3.8.2.

To do so, I need to change the CRS from Geographic to Projected. I did that to my raster layer, but when I try to do the same to any of my vector layers, they just disappear.

I am trying to change it from EPSG:4326 - WGS 84, to EPSG:25832 - ETRS89 / UTM zone 32N.

    Welcome to GIS:SE @WojtekAntoni! How did you change the CRS of your raster and vector layers? – Joseph Sep 5 '19 at 12:53
  • thanks! right click on the layer in the toolbar -> set CRS -> set layer CRS. Then I searched for the one I needed and double clicked on that. – Wojtek Antoni Sep 5 '19 at 13:00

    For any kind of analysis, make sure to reproject it which saves the spatial data in the new CRS. For vectors, you can use the Reproject layer tool; for rasters, you can use the Warp (reproject) tool. Both of these are available from the Processing Toolbox. – Joseph Sep 5 '19 at 13:05
