Area mission with terrain-follow
Plan photogrammetry missions that match the accuracy of manual total-station surveys — at a fraction of the time. Terrain-follow keeps the GSD constant over hills, ridges, and drainage cuts.
Why Muninn
Muninn samples a worldwide elevation dataset at every waypoint and holds AGL constant across the mission. Terrain-follow is available on every plan — no subscription wall.
Lawnmower N-S + E-W passes in one mission. Doubles photo count but delivers measurably tighter Z-accuracy in the orthomosaic.
Cloud 3D jobs return GeoTIFF orthophotos, LAS point clouds, and GLB meshes. Drop them straight into any open-source GIS stack.

FAQ
With GCPs + PPK/RTK drone: 2-3cm horizontal, 3-5cm vertical. Without GCPs: 30-100cm absolute, 2-5cm relative. Good enough for grading and volumetrics; not for property boundaries.
No for relative accuracy. Yes for absolute accuracy without GCPs. Matrice 350 RTK + P1 is the reference platform; Mavic 3 Enterprise RTK is the consumer-grade option.
Yes — Muninn exports GeoTIFF orthophotos and LAS point clouds that every major survey package ingests (QGIS, ArcGIS, CloudCompare, Trimble Business Center).
