The imagery obtained from UAVs can immensely support in many applications ranging from large-scale mapping, disaster assessment, infrastructure planning, urban modeling to vegetation structure mapping. Specifically in the NE region of our country with limited connectivity and difficult terrain condition, the local planning and developmental activities can be greatly improved by the UAV survey. NESAC has conducted 60+ UAV surveys until the date to assist different line departments and research work in NER. NESAC has also facilitated all the State Remote Sensing Centres of NER in establishing UAV facility under the project “Use of Unmanned Aerial Vehicle (UAV) Remote Sensing (UAV-RS)) for the States of NE region (NER)” funded by NEC.

Telemedicine is one of the vital SATCOM application programs of ISRO. The Telemedicine Program is an ICT enabled process of synergising benefits of Satellite communication and information technology with Biomedical Engineering and Medical Sciences to deliver the health care services to the remote, distant and underserved regions of the country. ISRO made a modest beginning in telemedicine using satellite communication in the form of a telemedicine pilot project in the year of 2001, connecting Apollo Hospital at Chennai with the Apollo rural hospital at Arogonda village in the Chittor district of Andhra Pradesh. Now a number of telemedicine networks are operational all over the country.

Unmanned Aerial Vehicle – UAV popularly known as drone, is an airborne system or an aircraft operated remotely by a human operator or autonomously by an onboard computer. There are two broad classes of UAVs – Fixed wing and Rotary based. UAV combined with remote sensing technology have been creating new vistas in global scenario to acquire the geospatial data on land resources and environment. The imagery obtained from UAVs can immensely support in many applications ranging from large-scale mapping, urban modelling to vegetation structure mapping. Specifically in the NE region of our country with limited connectivity and difficult terrain condition, the local planning and developmental activities can be greatly improved by the UAV survey.

IT and GeoInformatics Group is the backbone of the Centre to provide various operational IT and GeoInformatics related services. The group is responsible for establishing high technology infrastructure support to enable NE states to adopt space technology inputs for their development. Following are the major objectives of the group:

Photogrammetry and UAV division provides complete solutions for all standard tasks in digital Photogrammetry services such as Aerial Triangulation (AT), DSM/ DTM generation, Photogrammetry mapping, stereo compilation, topographic and planimetric feature extraction, orthophoto production, color balancing, contour generation, alignment studies for canal/road/railways, cut and fill volume estimation – volumetric analysis, L-section & cross-section profile generation, 3D terrain visualization and photo-realistic 3D city modeling.
