ABSTRACT

Telegeoinformatics, as an emerging discipline, integrates the techniques and technologies of geoinformatics, telecommunications, and mobile computing. Geoinformatics, as a distinctive component of Telegeoinformatics, is based on Geographic Information Systems (GISs), remote sensing and geolocation techniques, such as the Global Positioning System (GPS), or in general, Global Navigation Satellite Systems (GNSS), to gather and process geospatial position and attribute information. Geospatial data can be also acquired by digitizing maps, or by traditional surveying methods. However, modern techniques fully rely on remote sensing supported by GNSS used for georeferencing of airborne and satellite imagery. Thus, GNSS, remote sensing, and GISs are considered fundamental geospatial technologies, supporting acquisition, analysis and distribution of geospatial data. Satellite radionavigation approaches are also widely used in mobile mapping, which rapidly transforms from emerging to well-established, fully digital and automated technology, serving as a primary data source of data on road networks, facilities and infrastructures. Georeferenced, remotely sensed data are subsequently processed using photogrammetric methods, and converted to intelligent information stored in GIS databases.
