Always invoke for terrain, drainage, viewshed, or visibility analysis from elevation, even before the DEM or correct surface is chosen. Covers DTM-versus-DSM selection, slope, aspect, curvature, hillshade, conditioning, flow direction/accumulation, streams, watersheds, and catchments. Use point-cloud-lidar first only when an elevation surface must be created from LiDAR or photogrammetric points.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'terrain-hydrology' ] || [ -L ~/.agents/skills/'terrain-hydrology' ]; then echo 'A skill folder named terrain-hydrology already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/muend/geoai-skills' "$d" && git -C "$d" checkout --quiet '19937ce14c7d60d764732cc2688c6a3dd92f6d0e' -- 'skills/terrain-hydrology' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/terrain-hydrology' ~/.agents/skills/'terrain-hydrology' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'terrain-hydrology' ~/.claude/skills/'terrain-hydrology' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
