Since geophysics is concerned with the shape of the Earth, and by extension the mapping of features around and in the planet, geophysical measurements include high accuracy GPS measurements. These measurements are processed to increase their accuracy through [[differential GPS]] processing. Once the geophysical measurements have been processed and inverted, the interpreted results are plotted using GIS. Programs such as [[ArcGIS]] and [[Geosoft]] were built to meet these needs and include many geophysical functions that are built-in, such as [[upward continuation]], and the calculation of the measurement [[derivative]] such as the first-vertical derivative.<ref name="Telford" /><ref name=Reynolds>{{harvnb|Reynolds|2011}}</ref> Many geophysics companies have designed in-house geophysics programs that pre-date ArcGIS and GeoSoft in order to meet the visualization requirements of a geophysical dataset.
