Abstract
Geographic Information system is a computer based programme by which the data can be stored, retrieved, manipulated and analyzed
and the results are obtain in the form of maps. It helps in planning, improving of organizational integration, making better decisions
and making map. GIS was introduced during late1960s. In Pakistan various organizations are using GIS such as SUPARCO, Pakistan
Forest Institute (Peshawar), NWFP Forest Department, Environment Department (Punjab University), Sindh Forest Department,
Sindh Wildlife Department and some NOG’s & Petroleum companies. This study reports on the records of satellite data from tags
fixed on two female turtles (Chelonia mydas) and GIS mapping of the location of marine turtles and their migration pattern. The
movement of two turtles fixed with satellite transmitter of their carapace was monitored through GIS and their location was recorded
by sophisticated satellite-based data system (ARGOS). The study was carried out in collaboration with WWF-Pakistan and ERWDAUAE. The results show that turtles visit beaches at every 13-15 days. Turtles may remain restricted in a localized area and can also
migrate great distances in a short time. This study will be helpful for better management and research of marine turtles in Pakistan.
