Abstract:
Abstract We present a new global model of spherical gravimetric terrain corrections which take into account the gravitational attraction of Earth's global topographic masses at 3” (~90 m) spatial resolution. The conversion of Shuttle Radar Topography Mission (SRTM)-based digital elevation data to implied gravity effects relies on the global evaluation of Newton's law of gravitation, which represents a computational challenge for 3” global topography data. We tackled this task by combining spatia...     »
