Topographic Survey Directorate

A+    A-


The work of this Directorate is to determine the locations and nature of the features of the natural and built environment from direct measurement on the ground and from imagery derived from sensors in aircraft and on satellites.  Processing these measurements for storage in a geospatial database allows the generation of maps and imagery products at various scales as both digital and hard-copy products, available for sale.

This Directorate also manages the Geodetic infrastructure including the GNSS Permanent Reference Network  and accurate transformation models to relate positions in Bahrain to global coordinate systems.
