The Southern Gulf NRM GIS commenced in mid 2006 and was developed primarily for Natural Resource Management (NRM) purposes as outlined in the SGC NRM Plan (2005), and the Regional Investment strategy (2005). This development took place with an emphasis on immediate delivery in the areas of detailed property mapping as a fundamental requirement for property management planning, as well as capacity building of the region through training in GPS use and computer mapping software. The increasingly strong demand for GIS in the northwest has led to a broad range of products and services being delivered to all regional sectors.
The Global Positioning System (GPS) is a global navigation satellite system (GNSS) developed by the United States Department of Defense and managed by the United States Air Force 50th Space Wing. It is the only fully functional GNSS in the world, can be used freely by anyone, anywhere, and is often used by civilians for navigation purposes. It uses a constellation of between 24 and 32 medium Earth orbit satellites that transmit precise radiowave signals, which allow GPS receivers to determine their current location, the time, and their velocity. Its official name is NAVSTAR GPS. Although NAVSTAR is not an acronym, a few backronyms have been created for it. Since it became fully operational on April 27, 1995, GPS has become a widely used aid to navigation worldwide, and a useful tool for map-making, land surveying, commerce, scientific uses, tracking and surveillance, and hobbies such as geocaching. Also, the precise time reference is used in many applications including the scientific study of earthquakes and as a required time synchronization method for cellular network protocols such as the IS-95 standard for CDMA.
A geographic information system (GIS) captures, stores, analyses, manages, and presents data that is linked to location. GIS applications are tools that allow users to create interactive queries (user created searches), analyse spatial information, edit data, maps, and present the results of all these operations.
