fabdem

MCP server for radio line-of-sight checks: can a hiking route or point reach a repeater? Uses local FABDEM bare-earth terrain (30 m), with Earth curvature, k-factor refraction and Fresnel zone clearance. Takes waypoints, GPX or GeoJSON routes and reports coverage segments, gaps and verdicts at named stops. Works offline once tiles are cached.

Topographic map of Valle Escondido, Boquete, Panama, for a local hiking group: FABDEM 30 m elevation, 10 m contours, and OpenStreetMap roads, streams and trails, made with GDAL and ImageMagick.

Raster DEM conditioning, D4 river geometry, and optional bathymetry lowering for flood-model workflows.
