Abstract
The northeast Libya area acquired great interest by the Libyan Industrial Research Center (LIRC), so they contracted with a number of companies to produce 1:250,000 scale geological survey maps for the area. Those companies were of different scientific references and different nationalities, which led to the production of metal maps differ in their mineral classifications, and the symbols used in identifying the mineral, which caused a lack of clarity of the information when producing unified map of the area. This paper aims to improve the mineral information available from these maps using Geographic Information Systems (GIS) and remotely sensed data (e.g. satellite images). The unification of the map projection system for the whole area was done. A data-base was designed representing the mineral resources located in the northeast Libya area. A unified classification of mineral resources was established based on the existing geological maps and the satellite images interpretation. Also general mineral map was produced and good results were achieved.
