I'm relatively new to QGIS. I've used it for viewing various sources of
data and some vector editing and geoprocessing. Now, I'd like to do
some basic raster processing, like simply multiplying and adding
rasters, conditional expressions (e.g., if value < 0, then = 0, else
value), slope, aspect, etc....
What is the method to do these via QGIS? GRASS may be an option but I
understand it takes some preprocessing to get your files into GRASS
datasets, which could be a lot of work (numerous data sets, some several
GBs in size.) Thanks.
