Measured values come from the DEM. Assumed values come from GM02001's conceptual design basis. The two are visually distinguished so a technical director can tell which is which.

Resolution is collection-dependent and is never assumed. Licence is recorded per collection because the portal's own catalogue record reads “Access Only” — OQ-035.
Terrain stability mapping covering this location — susceptibility map not an event inventory, and not a hazard rating
Nearby past award 86002MJ4599
Four things that must never be conflated: an inventory, a susceptibility map, terrain-stability mapping, and an event database.
