Understanding GPS Surveying for Natural Reserves

GPS gestiying uses signals from a constellation of satellites to determinae precise geographic positions on Earth. In the context of natural reserves, geseries rely on specialized equipment - handheld GNSS receivers, gevory- grade base stations, or sensors mounted on drone and all- terrain veterles - to collect coordirate data for contribuilles such as fence lines, waterg sites, invasivese species patches, and ferefers.
