We study the practical aspects of performing terrain corrections in airborne/seaborne gravity gradient surveys in terms of necessary spatial extents and required resolution of digital elevation models. We develop a new and practical method for performing terrain corrections through an extension of Parker’s 1972 method for calculating potential anomalies in the Fourier domain. We then study and ...

A system to visualize and edit digital elevation models based on interferometric synthetic aperture radar data is presented. The visualization and exploration of digital elevation models has been traditionally achieved through the use of two-dimensional interfaces. As virtual reality interfaces have increasingly proven to offer a high degree of presentation realism and several interaction facil...

For a given terrain to be traversed, it is computationally intensive to determine the fastest route between two points, and for defense or civilian emergency dispatching applications, computation time is critical. This paper reports the integration of a 24 x 25 random access array of digital processors which are programmed to model a given terrain and determine the fastest (lowest cost) path fr...

Constructing an accurate Digital Terrain Model is costly and time-consuming, leading to more challenges in urban environments due the presence of different objects. This research performs step by analysis LiDAR data using a rule-based algorithm create automatic DTM. method needs no extra has precision equal that DTM, which constructed manually. The DTM this was compared manually investigate acc...
