Step fusion problem #23

Open katagen opened 1 year ago

katagen commented 1 year ago

I have made 3 groups, so I have 3 rasters layers that have a size between 150 and 450 Mo. At the step "fusion", I just select the order and then launch the script. The "merged" raster starts, but never end. When I stopped the process, the merged raster had around 33 Go !!!! Any idea what is happening? I never had that before the update of 1.2.1, one the same computer and the same version of Qgis?!?

Seems odd, I have never seen this behaviour. Could you check in layer properties Data Type and Width x Height parameters ? These parameters should be the same for selection outputs and merge ouptus.

OK, I made some tests, and I found a way to make it works! I have a vector layer as land use (like Corine land use). On the first try, I first rasterized it (Int16), and I use this raster in Biodispersal (in "selection" panel)... and here comes the error above. If I use the vector layer in Biodispersal (in "selection" panel) and it is the plugin that rasterizes it, everything works great!
