IRS and INSAT satellites helped in assessing the extent of damage and enabling the relief operators to use this data for planning the mitigation measures as well as establishing emergency communication system. Communication: For Andaman & Nicobar Islands a fly-away VSAT, 10 INMARSAT telephones and four INSAT Mobile Satellite Service (MSS) Phones were airlifted. VSAT based video conferencing facilities were set-up to connect seven Taluk HQs to Govt. Secretariat in Port Blair (capital of A&N Islands). Regular video-conferencing facility was established between these locations and the main land via INSAT-3E. Video conferencing facility was used to identify and locate the near and dear ones in different islands. Required transponder capacity on INSAT-3E satellite was earmarked for supporting large capacity telephone links from A & N Islands to Kolkata which is connected to Delhi. Telephone links from one place in A&N Islands to any other place through transportable VSATs were arranged. Space Technology in Relief and Damage Assessment in India

Telemedicine: Two Hospitals at Port Blair (GB Pant Hospital and INS Dhanvantari Hospital) and Indira Gandhi Hospital at Car Nicobar (A&N Islands) are part of the ISRO Telemedicine Network of 90 hospitals. This network enabled the local Doctors to communicate with speciality hospitals like Apollo Hospital at Chennai and Amrita Institute of Medical Sciences at Kochi. Large number of injured people used this facility. Space Technology in Relief and Damage Assessment in India (Contd.)

Slide6: 

Damage Assessment through Satellite Remote Sensing: Data from Indian Remote Sensing satellites (IRS-1C, 1D, OCEANSAT-1 and RESOURCESAT) of affected areas were used for analysis and damage assessment and the information was provided to Crisis Management Group (CMG) of the Ministry of Home Affairs and State agencies. Aerial Photos for damage assessment: Fresh Aerial photos have been collected for all affected areas and analysed for damage. As a member of the International Charter on Disaster, ISRO activated the Charter on Dec 26, 2004 and the satellite data from foreign satellites such as SPOT, RADARSAT and ENVISAT over Port Blair, Car Nicobar, Cuddalore and Nagapattinam were received and used for damage assessment. Affected areas of Sri Lanka and Maldives are also studied using IRS data. Space Technology in Relief and Damage Assessment in India (Contd.)
