Description

The elevation was accessed for the area of interest in 90 m spatial resolution from the TanDEM-X 90 m digital elevation model (DEM) product (Krieger et al, 2013). Prior to spatial topographical parameters extraction, the DEM was resampled  from the 90-m cell spacing to a 30-m resolution. The result was classified into 589 different possible combinations of elevation, slope angle, aspect. For the classification we used the possible combinations of elevation, slope, and aspect which were grouped into the following categories:

Elevation:

  • 0-400 m
  • 400-450m
  • 450-500m
  • 500-600m
  • 600-650m
  • 650-700m
  • 700-1000m
  • 1000-1500m

Slope:

  • 0-2°
  • 2-4°
  • 4-6°
  • 6-8°
  • 8-10°
  • 10-12°
  • 12-16°
  • 16-18°
  • 18-20°
  • 20-25°
  • 25-50°

Aspect:

  • 0-45°
  • 45-90°
  • 90-135°
  • 135-180°
  • 180-225°
  • 225-270°
  • 270-315°
  • 315-360°
