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...

In this paper, to separate regional-residual anomaly maps and to detect borders of buried geological bodies, we applied the Cellular Neural Network (CNN) approach to gravity and magnetic anomaly maps. CNN is a stochastic image processing technique, based optimization of templates, which imply relationships of neighborhood pixels in 2-Dimensional (2D) potential anomalies. Here, CNN performance i...

All sorts of anomaly graphs of physical geography and geochemistry, such as aeromagnetic anomaly graphs, bouguer gravity anomaly graphs, regional geochemical anomaly graphs and so on, are all parameters for exploration deposit. And following the remote sensing image shortwave and infrared bands coming, researchers of remote sense have engaged in many highly effective experiments and have approv...

Phlegraean Fields is a large, active caldera located in the densely populated westernmost sector of Naples’s Bay (Southern Italy). Several Bouguer anomaly surveys are available for this area with different resolution and accuracy; gravity data derive from integration stations placed below above sea level as develops both onshore offshore. The comparison these maps Digital Elevation Model shows ...
