I need to produce in QGIS a square having a specific dimension (1km x 1km). First I created a new polygon layer, but when I start editing through the Advanced editing tool, the program crashes. I guess that there is something wrong in my procedure.

Beside that tool, does the 3.x version (I'm using Madeira) allow me to create such squares using another method?

  • Your layer should be in a CRS that uses meters as its units. If it's not, create a new layer that is. – csk Sep 20 at 16:39

When you try to create a new polygon, you can use the Advanced Digitizing, Remember the tool don't work with geographic coordinates.

  1. Click in Toogle Editing. enter image description here
  2. Click in add polygon feature.enter image description here
  3. Click in Enable advanced digitizing tools. enter image description here
  4. In Advanced Digitizing Menu, with d = 1000 (meters, I suppose is meters, that depend of you coordinate reference), and block with this tool. enter image description here
  5. finaly, play with the coordinates in a section.

enter image description here

The result will see like this:

  • Thank you very much. I tried several times but unfortunately I cannot finish the procedure, first, I cannot create the square (I have to write the coordinates x,y first), then, even if I produce a sort of polygon, then the program always stop working. I am using EPSG 3003. I wonder if it is a problem linked to version 3.4. – Geo_it Sep 24 at 9:13
