GIS and Remote Sensing

Disaster assessment and management

Geographic information system and remote sensing are extremely valuable and powerful instruments in a debacle administration. Different debacles like seismic tremors, avalanches, surges, fires, torrents, volcanic ejections and violent winds are common dangers that murder bunches of individuals and pulverize property and frameworks consistently. Avalanches are the most consistent geographical vulnerabilities in mountain locales, especially in Sikkim Himalaya. Remotely detected information can be utilized productively to evaluate seriousness and effect of harm because of these calamities. In the debacle alleviation stage, GIS, assembled with global positioning system (GPS) is to a great degree valuable in inquiry and protect operations in ranges that have been crushed and where it is hard to discover one's direction. Catastrophe mapping is the drawing of territories that have been through inordinate characteristic or man-made inconveniences to the typical environment where there is lost life, property and national frameworks.
