I'm working on the preparation of the statement of Agricultural Capacity in general terms the *final map* has classes ranging 1-8.
To get this map I use three themes with their respective notes: - Map of Slope: with classes ranging 1 to 8; - Soil Map: with classes ranging 1 to 8; - Map of flood risk: with classes ranging 1 to 8; I - After converting all to a vector format and "merge" the three layers, I have multiple polygons with various combinations, eg: a) 1,3,1 b) 5,2,1 c) 4,2,1 d) 1,1,8 II - To determine the final value of the class is chosen the highest value: a) 3 b) 5 c) 4 d) 8 I need to automate this task because the last step (II) is very slow (actually manually), which would be the best way to do this? I think the whole process can be done with the data in raster format, but have not found a formula that I can apply in r.mapcalc to this problem.
