I am a relatively new user of QGIS and encoutered a first major problem.

I am working with this dataset that converts the available geocoordinates into the European standard ETRS89-LAEA.This is a grid of 1-square-meter raster cells covering all of Germany. It does not contain the specific longitudes and latitudes for the objects in the dataset.

The data is available as a

  • CSV file that contains all the variables, also containing the grid cells
  • a raster file that only shows the location of each raster

Now I want to join both files so that the raster file that indicates the location in QGIS contains the data of the CSV file.

This does not work out: I used the command Join attributes by location but it does not find the csv file. I think the problem lies in the fact that the spatial dimension of the csv file is not recognized.

How can I change that and produce a join as described above?

  • Did you try adding the csv file as a vector layer?

  • Yes, I indeed tried that. If you use ´´´Join attributes by location´´´ it does not even display the csv file (added as vector layer) due to the missing spatial index. Commented Sep 21, 2023 at 12:26
