Land Surveying deals with the field of Geomatics which is derived from the word "geo" (meaning of the earth) and "matics" (a derivative of informatics). The recent introduction of geomatics is because of the “digital revolution” which has revolutionised the traditional instruments and also our methods of presenting and transmitting that information.
Geomatics therefore is a discipline with focus on acquisition, processing, management, presentation and dissemination of information about the earth and features with a fixed location on the earth surface.
