India: Satellite images and communication equipment provided by the Indian Space Research Organisation (ISRO) are providing vital assistance for disaster relief teams, even as intermittent bouts of inclement weather continue to hamper the rescue of people stranded by floods and landslips in the remote areas of Uttarakhand, India. The Indian Institute of Remote Sensing (IIRS), Dehradun, is providing satellite-based information for rescue teams to identify the remote areas where people are likely to be stranded. The institute has prepared maps using satellite imagery. “These maps will be a valuable tool helping to trace missing people and reach relief material to affected areas,” P.K. Champati Ray, Professor and Head, Department of Geosciences and Geohazards, IIRS, said.
“The data from two Indian satellites, Cartosat 1 equipped with camera of 2.5 m resolution and Resourcesat with a camera of 5.8 m resolution, has revealed isolated clusters of houses, in mountainous terrain. Using the data we have prepared maps of 1:10000 scale on which we have marked the pilgrim trekking route and the areas prone to landslips as well as the remote villages where relief material has to be reached”, Dr Ray said. ISRO has also initiated efforts to acquire data from Risat 1, the Indian radar satellite capable of penetrating the cloud cover. “The high resolution camera on board this satellite does not cover a wide area. The available data is being analysed by the National Remote Sensing Agency,” Dr Ray said.
