The montaj™ Gravity and Terrain Correction extension provides a complete system for processing and reducing gravity data from conventional ground surveys.
Apply terrain corrections from digital elevation models (DEMs) or gridded elevation data. With the streamlined menu system, perform all the standard gravity processing steps quickly and easily.
In addition, the uniquely optimized terrain reduction algorithm delivers accurate corrections quickly, even for very large data sets. Geosoft’s terrain correction algorithm combines methods described by Kane†; and Nagy† with advanced grid-mesh interpolation, zoning and desampling techniques.
