dem_geodetic_from_enu — DEM `geodesy` op

• Data kinds: points → points

• Call: import fullseye as fs; fs.ledger.dem_geodetic_from_enu(enu, lat0_deg, lon0_deg, h0_m) (to call the implementation directly, import demops; demops.dem_geodetic_from_enu(enu, lat0_deg, lon0_deg, h0_m); from the registry, opsdem.get("dem_geodetic_from_enu"))

Usage

Local ENU → geodetic coordinates (the inverse of dem_enu_from_geodetic). points.

Args:

enu: (n, 3) of (east, north, up) [m].

lat0_deg / lon0_deg / h0_m: geodetic coordinates of the reference point.

Returns:

(n, 3) of (latitude[deg], longitude[deg], ellipsoidal height[m]).

Checkable by closed form: round trip at the 1e-9 m level; (0, 0, 0) is the reference point itself.

ValueError: not (n, 3), non-finite values, invalid reference point.
