Load data DEM

Generate Contour melalui menu File – Generate Contour

Agar kontur tersebut data terbaca pada ArcGIS maka harus dilakukan export shp melalui menu File –Export Vector Data – Export Shapefile

Load data DEM (ingat agar merubah proyeksi DEM menjadi UTM)

Buat slope degree melalui menu Spatial Analyst – Surface Analysis - Slope

Membuat kelas – kelas kelerengan melalui menu Spatial Analyst – Reclassify

Agar dapat melakukan perhitungan luasan maka harus dilakukan Convert data raster ke polygon melalui menu Spatial Analyst – Convert – Raster to features

Selanjutnya dilakukan dissolve untuk menggabungkan kelas – kelas kelerangan yang sama
Selanjutnya melakukan clip Area of Interest

Selanjutnya melakukan perhitungan luasan dari tiap-tiap kelerangan melalui menu Xtools Pro – Table Operations – Calculate Area
