When Your Terrain Ruggedness Index Hides Navigable Corridors: 3 Common Mistakes
You've got your DEM loaded, TRI calculated, and a nice red-to-green map showing where terrain gets rough. Looks clear: avoid the red, stick to the gre...
Choosing a Field Sampling Transect Without Missing Micro-Topographic Variability
You're standing at the edge of a meadow, map in hand, ready to lay out a transect. But the ground is not flat. It humps, dips, and tilts in ways your ...
When Your Landform Classification Overlooks Critical Edge Effects: What to Fix First
You've spent hours tuning a landform classifier—slope thresholds, relief windows, maybe a machine learning model. Then you check the output. Near ever...
