Accepted Answer

Buffer rivers  →  overlay with slope and soil layers  →  extract suitable areas /  Buffer riviere  →  oorl ê  met helling- en grondlae  →  onttrek geskikte gebiede

Answer

Interpolate soil data  →  clip slope  →  union rivers /  Interpoleer gronddata  →  knip helling uit  →  unie van riviere

Answer

Create contour lines  →  dissolve rivers  →  calculate NDVI /  Skep kontoerlyne  →  voeg riviere saam  →  bereken NDVI

Answer

Convert roads to raster  →  classify rainfall  →  create hillshade /  Skakel paaie om na raster  →  klassifiseer re ë nval  →  skep heuwelskadu
