LandsatThe lengthy awaited Landsat 8 satellite was efficiently launched from Vandenberg Air Drive Base in California, USA on Monday eleven February 2013 using the Atlas-V 401 rocket launch vehicle. Landsat 8 or the Landsat Data Continuity Mission (LDCM) as it’s currently known is a continuity mission in the sequence of Landsat satellites that was designed to succeed Landsat 5 and Landsat 7 missions. The Landsat collection of satellites have an unparalleled file of land imaging which dates back to 1972.

In 1972, Landsat-1 paved the way in which as being the first Earth commentary satellite tv for pc of the Landsat program – which is THE longest operating area-based mostly Earth remark program on the planet.

Based on remote sensing a variety of information pertaining to the coastal zone like, identification of plant neighborhood, biomass estimation, shoreline modifications, delineation of coastal landforms and tidal boundary, qualitative estimation of suspended sediment concentration, chlorophyll mapping, bathymetry of shallow waters, and many others. may be collected and all these knowledge will help in efficient coastal ecosystem administration.

A radiometrically corrected and geometrically corrected ETM+ digital Earth picture together with metadata, calibration parameters, and a geolocation table. The radiometrically corrected pixels are resampled for geometric correction and registration to a consumer-specified map projection. Stage 1G information merchandise are generated on request and the data are packaged and formatted for distribution to the information user.

A strip of knowledge from the primary Shuttle Imaging Radar Experiment (SIR-A) has been superimposed on a Landsat picture of the Western Desert of Egypt. Historical dried up river channels (wadis), usually coated by a layer of sand, are delineated much more clearly on the radar imagery. Identification of wadis, where water as soon as flowed freely, helps archaeologists to locate historic sites of human habitation.
