Re: [Qgis-user] QGIS 3 clipping raster with a polygon - problem

I have upgraded to 3.0.3 and tried to clip another file. Oh Joy! It worked. However I was a bit disconcerted by the GDAL readout at the bottom of the box which described output to a temp file even though I had specified a new filename and location. However, the new file name was actually applied.

just a wild guess: you have lots of spaces in your path and file names. This is to be avoided in general, cause lots of function may eat this, but lots of others may not. Try it with underscores instead of spaces. Am 24.05.2018, 15:25 Uhr, schrieb David Addy : Hi

I have had another go with another dataset. I have tried both these algorithms in QGIS 3.0.2: 1. Gdal ->" Raster extraction" -> "Clip raster by mask layer" 2. Saga -> "Vector <-> raster" -> "Clip raster with polygon" Both give an error message. In the case of GDAL it is :"GDAL command

2018-05-20 Thread David Addy
I have always been able to clip a raster using the mask made by drawing a polygon around the required area in QGIS 2. However, in QGIS 3 the process does not work the same way. I cannot figure out how to make a new output file, and whatever I try results in no comprehensible output. I have just
