the use of stokes boundary values problems for the determination of the geoid requires that gravity anomalies (as boundary values) are known on geoid (as boundary). while, the gravity observations are measured on the earth's surface, to obtain boundary data, the surface gravity anomalies does are downward from the terrain onto geoid. for downward continuation (dwc) of surface gravity anoma...

to solve the geodetic boundary-value problem the gravity anomalies have to be continued from the earth's surface down onto the geoid surface. helmert’s gravity anomalies (multiplied by the geocentric radius) are harmonic above the geoid. it is thus possible to use them in the poisson solution of the inverse dirichlet boundary value problem to get their values on the geoid. the downward con...

The archaeological use of images and data obtained through devices carried on mobile platforms (such as airplanes satellites) is already one century old. Today, aerial photography remote sensing are routinely used to capture, process analyse evidence present the surface earth, which reflected in a large body literature—see Bewley (1999), Corsi et al. (2013), Palmer Cox (1993), Piccarreta Ceraud...
