I've been trying to clip an area in a raster image which I have created from an OSM. However when I fill out the raster clipping form I get the following message.
Error 1: Output dataset. tif exists, but some command line options were provided indicating a new dataset should be created. Please delete existing dataset and run again.
I don't really get this because assuming I'm making a new layer with only the clipped part, I AM going to make a new dataset right?
