I have some data on population estimates in Germany for 1km by 1km squares. (Data can be found here: https://www.destatis.de/DE/Service/EXDAT/Datensaetze/bevoelkerung-geo-mobilfunkdaten.html when you scroll down to download.) The file you get is an excel with the Gitter-ID (Grid-ID, e.g. CRS3035RES1kmN2684000E4334000), some general information, and the population estimates. If I understand it correctly, the Gitter-ID refers to a point in the EPSG:3035 georeferencing system. My question is now how I convert this point to a square in GIS that uses the normal long-lat system, given that my other data that I have uses this system.

I have done a fair amount of search for this but could not figure out how to go about this. How can I do this?

You are correct, Gitter-ID are CRS3035 coordinates.

To use them in QGIS, first create columns with the N & E parts of the coordinates (split column by width in Excel), and export that Excel sheet as a .csv file

enter image description here

Then open this .csv in QGIS (add Text Delimited Layer) with X = the E part, Y = the N part of the coordinates, and CRS 3035 enter image description here

From there, you get a point grid over the whole country: enter image description here

You can then color the layer by a given column value, and to have clean squares select a Square symbol (Simple Marker), with Size = 1000 Meters at scale

Color by 'plausibilierung':

Symbol: 1000m square centered on the points

In Excel,

  1. Add two empty columns next to Gitter-ID.

  2. Split Gitter-ID text into different column with "Data > Text to Column". Use firstly N, then E as separator/delimiter. Enter Y and X names for new columns.

    enter image description here

  3. Save the active sheet as CSV.


Open "Layer > Add Layer > Add delimited Text Layer" window. Choose the CSV file. As shown in the image below:

  1. Specify delimiter.
  2. Check "First record has field names".
  3. Select X and Y column.
  4. Click "Select CRS" button.
  5. Type "3035" .
  6. Select the CRS from the list.

Final Step:

Use "Rectangles, ovals, diamonds" tool with Shape: Rectangle, Width:1000 and Height:1000 from "Processing Toolbox > Vector Geometry". The tool gives you a layer containing squares.

    Thank you so much to you, too! I have been struggling with this for a fair amount of time but now it seems to work. Thanks for taking the time to write this! :)
