[Qgis-user] Raster analysis , Proximity (raster distance)

[Richard McDonnell]

Hi Dimitris,
Welcome!!

To answer your question, use the Georeferenced coordinates and run, the distances will be based on the resolution of your image, so 5m resolution will result in a proximity raster of 5m intervals.
You might want to set the Maximum distance, as this will help to minimise processing and Image size.
Reagrds,

Richard.

Hello to all ,

This is my first message here. I am trying to create a proximity map with the Raster analysis tool. My problem is that I only get two options for distance units , pixels coordinates and georeferenced coordinates while I want to get them in meters.

I also used the grass tool , r.grow.distance that provides in advanced parameters the option "Output distances in meters instead of map units" If i check this option i get the following error ERROR: Raster map or group not found.

Does any of you know any workaround for this?

I am using QGiS 3.8.1 with GRASS 7.6.1

Kind regards
Dimitris
