Image of photogrammetry and remote sensing

Photogrammetry and Remote sensing Department, established in 1966 is one of the oldest departments of the institute imparting professional training in the field of photogrammetry, cartography, remote sensing, and image processing to varied course participants: university teachers, academicians, govt. officials, and freshly graduated students. Initially it started with aerial data interpretation, analysis and aerial photogrammetry with a gradual transition to satellite data interpretation, analysis, satellite photogrammetry and its applications. The training programmes are regularly updated by incorporating the state of art technology.

Regular Courses:

  • Basic and Advanced Modules on Photogrametry, RS and DIP in M.Sc. Programmes
  • M. Tech. in RS & GIS with specialization “Satellite image processing and Photogrammetry” (2 years programme)
  • Short course on Digital Image Processing sponsored by Indian Technical and Economic Cooperation (ITEC), Ministry of External Affairs (8 weeks Certificate course)
  • Short course on Geo-informatics sponsored by ITEC, Ministry of External Affairs (8 weeks Certificate course)
  • Digital cartography & Mapping course for university teachers under NNMRS (8 weeks course)
  • PG diploma in Photogrammetry and Remote Sensing (10 months program)
  • PG. Diploma in Advanced RS and GIS for participants from Asia Pacific region sponsored by Centre for Space and Technology Education in Asia and the Pacific (CSSTEAP), United Nations (9 months program)

Special Courses:

  • Large Scale mapping using High Resolution data
  • UAV Remote Sensing and Its Application
  • Lidar Remote Sensing and Its Application
  • Hyperspectral Remote sensing
  • Microwave Remote Sensing and its Application

The potential thrust areas of the department are advanced image processing using Hyperspectral, Microwave, LiDAR, Multispectral, Multi-temporal and High Resolution data, Satellite, terrestrial photogrammetry, GPS and Lidar for topographic information extraction and 3D modelling.
