Introduction Chapter: From Land Surveying to Geomatics - Multidisciplinary Technological Trends

Geodesy is a mathemati cal science that determines the shape and size of the earth and the nature of the earth’s The use of geomatics and its sophistication with the techniques are evolving and continue because of the need to integrate them with modern technologies to be used in several fields, including artificial intelligence, geo-analysis, and geospatial information. The availability of more sensors as a result of their low cost under the Internet, free and open source objects and software, and the availability of high-performance infrastructure all led to the development of geometrics. It is a science that includes many important aspects, so we focus on all geomatics trends.
