I have a set of points in lat/lon coordinates over Europe representing pixels from a satellite dataset. I know each pixel has size 10x10km.

I want to draw a square polygon around each single pixel with the size 10*10km. I have tried reprojecting and then drawing a square around it using the "Rectangles, ovals, diamonds" tool. But every time I get this way too big square drawn around the results (see the image below). I am not exactly sure how to fix or even tackle this issue.

Left: points, Right: drawn square

I have tried the methods suggested in this question as well.

    I would guess they are only square in the original projection of the satellite image so you need to go back to that

  • Buffer them by 5000 m using a m-based CRS (probably EPSG 3857, since your AOI is very large) and set the buffer end cap style to square and the join style to miter.

  • Hi Erik, they're already in EPSG:3857 and I've reprojected them as well. Selecting that as CRS still gives the same issue.

  • What is the CRS of the point layer?

  • Geographical coordinates, WGS84.
