The Project TR-GRAV was initiated with the support of the Turkish Republic Presidency of Strategy and Budget, with a view to modernizing Turkey’s outmoded height system with new approaches in light of scientific and technological developments and developing an infrastructure that would allow the use of country-wide geodetic gravity data to be used in other fields of earth sciences like geophysics, geology and mineral and petroleum exploration.
The Project was conducted from 2016 to 2020 with the cooperation of General Directorate of Mapping, General Directorate of Mineral Research and Exploration (MTA), Turkish Petroleum Corporation (TPAO), TÜBİTAK Marmara Research Center (MAM) and TÜBİTAK National Metrology Institute (UME). TÜBİTAK MAM Earth and Marine Sciences Institute (YDBE) made relative gravity measurements at 3655 points in total in its area of responsibility (40°N-42°N latitudes).
Republic of Turkey Presidency of Strategy and Budget expressed thanks to MTA, TPAO, TÜBİTAK MAM and TÜBİTAK UME for their efforts in conducting the project in line with the schedule.
