This project seeks to develop the next-generation model of Earth’s gravity field with ~100 m resolution for all land areas of our planet, including the Polar Regions and Australia’s Antarctic Territory. Based on our experiences within previously successful projects (e.g. GGMplus gravity maps), a new height reference surface and maps of all commonly used gravity field quantities will be obtained with unprecedented spatial resolution at more than 15 billion land points. Our research will confer benefits to geodesy (e.g., contributing to the observation of sea level change and global change studies, cost savings in surveying through economic heighting with satellite systems, reduction of surveying data), geophysics (use of our model as a new reference gravity data set) and provide scientific aid (through readily-usable computerized gravity field maps) to all developing countries. Computations will be carried out in 2015 and 2016, and completion is envisaged for ~2017.
