Description

Gravity ground survey data is obtained from the Libyan Petroleum Institute (LPI) located in Tripoli, the capital of Libya. The LPI collaborates with the Libyan Gravity Project (LGP). The LGP obtains data from numerous oil and gas companies working in Libya as well as from the NOC. The gravity data consist of 74,520 data-points taken at 1.0 km separation across the study area based on the Geodetic Reference System 1980 (GRS 80) at 2.67 g/cm³ reduction density. The aeromagnetic data is obtained from the African Magnetic Mapping Project (AMMP). The AMMP is part of a worldwide collaboration between Peterson, Grant and Watson Limited (PGW, Canada), GETECH (United Kingdom) and the International Institute for Geo-Information Science and Earth Observation (ITC, the Netherlands). Flight lines and data-points along each line are both 1.0 km apart. A total of 113 flight lines in the E-W direction and roughly 197 data points along each flight line resulting in about 22,270 magnetic data-points.
