Geomatics
Geomatics deals with spatial references and modeling of spatial reference systems. It includes the capture, management, modeling, representation, distribution and marketing of geospatial information using scientifically sound methods and procedures. Geomatics combines the disciplines of geodesy, surveying and geoinformatics and uses elements of geography, cartography and computer graphics.
Geographic information forms the basis for the planning, design and sustainable development of the environment. An investigation by the Department of Labor of the United States, the nanotechnology and biotechnology, followed by the Geoinformatics, as the fastest growing technologies of the future.
Core areas
The Geodesy come here, next to tasks such as engineering and industrial surveying, photogrammetry and the Facility and Land Management, the interdisciplinary major core tasks of production and continuation of the global terrestrial reference frame ( ITRF ) and the height reference surface definition ( geoid ) important provision of the Earth's gravity field to. The Geodesy uses for the former task to the global network of GNSS and VLBI stations of the International GNSS Service (IGS ), and for the Schwerefeldbestimmmung the observation of low earth orbit satellites ( LEOS ), as CHAMP, GRACE and GOCE, as well as terrestrial or aircraft gravity measurements and other methods of physical and satellite geodesy. ITRF and earth gravity and downstream fixed-point fields provide the reference for the future tasks of a globally networked Geomonitoring such as the capture of sea level changes, tectonic plate movement, geological and geotechnical hazard zones and the transport sector. The software development and software engineering within the Geomatics is a high priority to the data of altimetry, remote sensing, SAR and geodetic monitoring systems ) and with the use of geographic information systems (GIS ) to process.
Methods and technologies
Characteristic of the current developments in geomatics are the use of local, regional and global networks of sensors ( Geosensor Networks ), the global satellite positioning and navigation systems GNSS (GPS, GLONASS, Galileo, COMPASS ) and the associated terrestrial component of modern worldwide availability of GNSS reference station networks and positioning services (eg SAPOS ). These provide GNSS corrections ( RTCM, RTCA ) is ready for users real-time positioning accuracy in the range of one meter to one centimeter and form the foundation for the production of the global spatial reference for a variety of navigation tasks. The transfer of the GNSS positions in existing local user systems is an object of mathematical geodesy. The transmission of GNSS correction data via communications satellites, for example, EGNOS and the Internet.
Automated 3D vector measurement systems (total station ), inertial navigation systems (INS ), digital measuring cameras, terrestrial or used in the air 3D laser scanners allow for quick, accurate and reliable detection of spatial information. Powerful geospatial software enables a problem- oriented visualization for map display and on global networks (eg Web - GIS).

Graduates of Surveying and Geomatics, as well as the cartography and geomatics are active in the geo-referencing, analysis, processing, visualization and informative provision of geodata in networked systems (GIS ) for consulting engineers, industrial companies and government agencies. As of August 2010, the Education for Geomatics is possible. The Geomatics is a new professional training, the elements from the surveying, cartography, remote sensing together. The handling of spatial data located in the center of vocational training. So the teaching of a process chain from capture to spatial data processing ( interpretation, integration, analysis, storage ) to visualization and marketing content of vocational training.
