Landforms II: MORAP

This landform model builds directly on a previous post (Hammond Landforms). Use the .mxd and files created for that lesson.

MORAP RELIEF INPUT PARAMETER
1.) “Map38″ = Reclassify, input = Map11, 7 classes, BVs = 15, 30, 90, 150, 300, 900, max value, New Values = 1, 2, 3, 4, 5, 6, 7.

MORAP SLOPE INPUT PARAMETER
2.) “Map39″ = Reclassify, input = Map7, 2 classes BVs = 50, 100, New Values = 20, 10.

MORAP LANDFORMS
3.) “Map40″ = Raster Calculator     “Map39″+”Map38″
4.) “Map41″ = Smooth and remove noise via Focal Stats, input = Map40, 8×8 cells, rectangle, majority.
5.) “FinalMORAP” = Clip to boundary used for Hammond Landform map.
6.) Add labels to attribute table:
11-Flat plains
12-Smooth plains
13-Irregular plains
14-Plains with low hills
15-Plains with hills
16-Plains low mountains
17-Plains with mountains
21-Rough plains
22-Rugged plains
23-Breaks
24-Low hills
25-Hills
26-Low Hills
27-Mountains

7.) “FinalMORAPPolys” = Convert FinalMap to vector (polygons) with ArcToolbox > Conversion Tools > Raster to Polygon.
8.) Change symbology/color scheme.
9.) Create a hillshade raster, drag it to top of stack, change transparency to ~60%.
