I'm trying to obtain a raster of Euclidean Distances from a vector layer I have of a river in Spain. I did it very easily with ArcMap using Euclidean Distance, but I don't know how to do it in QGIS.this is the river polygon shapefile

I just want to obtain a raster with all the distances from the river so I can then reclassify it, so it would look like this one I already created with ArcMap. euclidean distance from ArcMap, already reclassified

  • I get this message when trying to convert to raster: "The output file doesn't exist. You must set up the output size or resolution to create it." I'm not sure what does it means to select an output file. Jul 22 '15 at 8:26
  • can you take a screen grab of the dialogue box before you run the tool? Jul 22 '15 at 15:11
  • You ask how to obtain a raster of euclidean distances to classify in the next step. Consider to simply create a multi distance buffer. There are 2 plugins available to accomplish that task.

  • Thanks a lot for your help but I figured it out! I wasn't specifying the pixel resolution and that's why the error message appeared. By the way, I didn't thought about the multi distance buffer, sounds reasonable. thanks! Jul 22 '15 at 20:12
