I need to create a vector layer for representing the geology of an area. I have the geological map, a raster file.
I made some polygons and I named them in the attribute table, but I don`t want to spend time writing the name of the rocks associated with each polygon. I made another field named code and I want to correlate those codes with the polygon names, so when I introduce that code, the name associated appears.
I think that I can do this in Field Calculator, but I don`t know how.
Is there any possibility to do this ?
