New Dimensions of Map Science (E)
India has built a rich base of maps using the detailed topographic surveys, geological surveys, soil surveys, cadastral surveys, an inventory programme of various natural assets and remote sensing image. The spatial data sets are obtained using satellite images, global positioning system (GPS) and geographical information system (GIS).These spatial data sets are used in almost all developmental projects at the national level. The new technologies like IoT,AI and cloud have been included to upgrade the geospatial information. Geospatial information will be one of the important elements in the concept of unified information infrastructure.
