Surface water
Major surface water features of Libya. Map developed from World Wildlife Fund HydroSHEDS; Digital Chart of the World drainage; and FAO Inland Water Bodies. For more information on the map development and datasets see the surface water resource page.

Soil

Soil Map of Libya, from the European Commission Joint Research Centre: European Soil Portal. For more information on the map see the soil resource page.

Land cover

Land Cover Map of Libya, from the European Space Agency GlobCover 2.3, 2009. For more information on the map see the land cover resource page.


Geology

The geology map on this page shows a simplified version of the geology at a national scale (see the Geology resource page for more details).

Geology of Libya at 1:5 million scale. Developed from USGS map (Persits et al. 2002). For more information on the map development and datasets see the geology resource page.

Hydrogeology

The hydrogeology map below shows a simplified version of the type and productivity of the main aquifers at a national scale (see the Hydrogeology Map resource page for more details).

More information on the hydrogeology of Libya is available in the report United Nations (1988) (see References section, below).



Transboundary aquifers

For further information about transboundary aquifers, please see the Transboundary aquifers resources page.
