Pakistan Wetlands GIS - a multi-scale national wetlands inventory

摘要

Pakistan possesses a great variety of wetlands distributed throughout the country whose number exceeds over 200 identified wetlands or wetland complexes. The information about these resources is patchy and has not been compiled and updated systematically except documentation of only 48 wetlands in the Asian Directory of Wetlands in 1989. In order to fill the information gap, GIS-based Pakistan Wetlands Inventory (PWGIS) is developed under Pakistan Wetlands Programme (PWP). The spatial framework of PWGIS follows Asian Wetlands Inventory guidelines. FAO's Land Cover Classification System (LCCS) is adopted to harmonize the legend at all the scales. A Spatial Data Infrastructure (SDI) is developed at National Council for Conservation of Wildlife (NCCW) that has deployed PWGIS to use, maintain, improve and distribute it among other conservation organizations.
