Centre’s Data Bank is depository of primary data in the form of Survey of India- Topographical maps to prepare base information, whereas Aerial Photographs and Space borne satellite coarse, medium and high resolution data act as a secondary information to generate various thematic layers, which are very necessary to implement various type of scientific projects in the Centre.. To fulfill the requirements of the various projects a Data Bank has been established in the Centre since it’s inception. Data Bank is a depository of about 11517 SOI-Topographical sheets in the form of hard copy including 335 Digital Topographical maps, about 39170 Aerial Photographs as well as (FCC-5767, Digital DVD -4143 data.) about 9920 Satellite Data.
