GIS & REMOTE SENSING
Remote sensing (RS) is an art and science of obtaining information about physical characteristics of an area by measuring its reflected and emitted radiation at a distance to help of Satellite or Aircraft.
In below list of Remote sensing Analysis Tutorial.
LiDAR– Light Detection and Ranging Introduction Light Detection And Ranging (LiDAR) is a remote sensing method used to examine the surface of the Earth. It uses eye-safe laser beams to see the world in 3D, providing machines and computers an accurate representation of the surveyed environment. Lidar is an optical means of measuring reflected light […]
RADAR- Radio Detection and Ranging Introduction Radio Detection and Ranging (RADAR) is a detection system that uses radio waves to determine the distance, angle, and radial velocity of objects relative to the site. It is widely used in applications ranging from military surveillance to weather forecasting and geographical mapping. The term Radar was minted in 1940 by
SRTM- Shuttle Radar Topography Mission On 23 September 2014, the White House announced that the highest-resolution topographic data generated from NASA‘s that is Shuttle Radar Topography Mission (SRTM), it was released globally by late 2015. The Shuttle Radar Topography Mission is elevation data on a near-global scale, acquired from the Space Shuttle, to generate the
Digital Elevation Model (DEM) Download Digital Elevation Model (DEM) widely known as a Digital Terrain Model (DTM). A DEM can be used to create topographic maps of overland terrain, as well as bathymetric maps. A DEM data can be represented as a raster dataset, or as a vector-based Triangular Irregular Network (TIN). Best 6 Free
Digital Elevation Model (DEM) A Digital Elevation Model (DEM) is a represent ground/Earth Surface Topography or Terrain. It is also widely known as a Digital Terrain Model (DTM). DEMs are commonly built using Remote Sensing techniques and also used often in GIS. A DEM data are stored in ASCII format. The data file values in ASCII
