I would like to be able to take all values between 1 and 10 and have a field define them as 1, and all values between 10 and 20 and set them to 2, how do I do that with vector data?
I read how to set all building to 20, and grass to 40, but I'm pretty sure that to do that for a range of values, like 1-10, I would have to manually enter each number, and decimal in that range. Am I wrong? and if not, how would I accomplish this?
