ArcGIS T19: How To Calculate Automatically % Imperviousness From LULC (2/2)
In this tutorial, I have demonstrated how to calculate percentage Imperviousness automatically using model builder from Land Use and Land Cover dataset. The imperviousness has been calculated per subbasin and saved as excel files.
You can use the python code to reclassify the LULC:
def classify_landuse(gridcode):
if gridcode ==1:
return "Water"
elif gridcode ==2:
return "Developed"
elif gridcode ==4:
return "Mechanically Distributed Other Public Lands"
elif gridcode ==5:
return "Mechanically Distributed Private"
elif gridcode ==6:
return "Mining"
elif gridcode ==7:
return "Baren"
elif gridcode ==8:
return "Deciduous Forest"
elif gridcode ==9:
return "Evergreen Forest"
elif gridcode ==10:
return "Mixed Forest"
elif gridcode ==11:
return "Grassland"
elif gridcode ==12:
return "Shrubland"
elif gridcode ==13:
return "Cropland"
elif gridcode ==14:
return "Hey/Pasture Land"
elif gridcode ==15:
return "Herbaceous Wetland"
elif gridcode ==16:
return "Woody Wetland"
