<div>I'm working on the preparation of the statement of Agricultural Capacity in general terms the <b>final map</b> has classes ranging 1-8.</div><div> </div><div>To get this map I use three themes with their respective notes:</div>
<div><ul><li>Map of Slope: with classes ranging 1 to 8;</li><li>Soil Map: with classes ranging 1 to 8;</li><li>Map of flood risk: with classes ranging 1 to 8;</li></ul></div><div>I - After converting all to a vector format and "merge" the three layers, I have multiple polygons with various combinations, eg:</div>
<div>a) 1,3,1</div><div>b) 5,2,1</div><div>c) 4,2,1</div><div>d) 1,1,8</div><div> </div><div>II - To determine the final value of the class is chosen the highest value:</div><div>a) 3</div><div>b) 5</div><div>c) 4</div><div>
d) 8</div><div> </div><div>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.</div>
