Geomatics is the discipline of gathering, storing, processing, and delivery of geographic information, or spatially referenced information. It involves traditional sciences such as geodesy, surveying, photogrammetry, mapping, cartography and hydrography. These traditional sciences are strengthened using computers, communications and special software written to assist and enhance the traditional techniques. This marriage of computers with the traditional sciences results in many new systems like geographical information systems, remote sensing systems, digital terrain modelling, global positioning systems, location based services, and navigation. Some of the key technologies that impact the field of geomatics are GRID and cloud computing, wireless ad hoc networks, sensor webs, web 2.0 and semantic web, ubiquitous computing, high performance computing and mobile computing. These technologies can be adapted to the specific requirements of geomatics and this presents several areas of research which should be of interest to engineers working in these fields. A working knowledge of physical geography and an interest in communications technologies and computational techniques are prerequisites
