I have a shapefile containing many thousands of polygons with values ranging 0-105. I would like to create a much simplified file that contains classes for value ranges. E.g. values 30-50 = class 1, values 50-70 = class 2, values 70-100 = class 3. The classes can be integers. The attributes from...
