Calculation of gravitational corrections using airborn laser scanning data

Calculation of corrections to gravity measurements is one the most important stages that determine whole quality research. Wrong can lead incorrect interpretation obtained and their false interpretation. To achieve highly accurate results, it necessary take into account not only height, but also entire array information about relief. In this case, level detail relief model becomes critically important, especially in case working with rugged terrain large number vertically developed rock formations (outliers, faults, steep slopes). Now methods normally used are based on use previously created materials from cartographic archives (topographic maps at a scale 1:100,000–1:25,000). It possible open (free) models. These have drawbacks, for example, low microrelief inclined surfaces (slopes, walls, incisions) significant effect values measured by gravimeters located small distance such forms. The available do assume ability work dense shortcomings wrong during gravimetric measurements. however, using modern remote sensing makes obtain high-precision models easily. best opportunities provided lIDAR technology. here we describe differences between data other types (1:25,000 maps, models), make comparison corrections, calculated different sources.
