GTB: Topo

compute the "usual" relief attributes !

Topo is a compilation of grid commands to calculate the standard, usual terrain parameters, so no mistyping, forgetting parameters, different approaches and so on. More description in my PhD thesis - Citation

INPUT

Input Data - Elevation

COMMAND

Command Call with stream threshold set to 100 cells

RESULTS

Aspect of Input DEM

Slope of Input DEM

Slope of Input DEM (adjusted for TWI/SPI/STC calculations)

Curvature of Input DEM

Profile Curvature of Input DEM

Inverse DEM

Flow direction of Input DEM

Flow accumulation of Input DEM

Flow accumulation of Input DEM (adjusted for TWI/SPI/STC calculations)

Pour Points of Input DEM

Ridges of Input DEM

Basin IDs of Input DEM

Basin Area of Input DEM

Stream network
