GroundSignal cross-references NASA satellite radar with the public landslide and hazard-zone record, then distils both into a plain-English stability read for any residential address on the West Coast. Run it before you tour. Run it before you offer. Run it before a geotech survey eats three weeks of your client's patience.

Honest about the limits.
Satellite radar reads bare and built ground cleanly — streets, foundations, slopes, retaining walls. It struggles to read through dense living cover: evergreen forest, vineyards and orchards, and heavily irrigated farmland scatter the signal between passes, so some parcels in those areas can't be scored from space.
When that happens, the report tells you plainly that the radar couldn't get a clean look — and you're not charged. We'd rather say “we couldn't see this” than guess.
