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.

ENVI Software: Download, Install, and Analyze Introduction ENVI, which stands for Environment for Visualizing Images, is a powerful and widely used software developed by L3Harris Geospatial Solutions, launch in 1994. It is specifically designed for the visualization, processing, and analysis of geospatial imagery obtained from satellites, drones, and airborne sensors. ENVI has become an essential […]
Orthorectification What is Orthorectification? Orthorectification is a form of rectification that corrects for terrain displacement and can be used if there is a DEM of the study area. It is based on collinearity equations, which can be derived by using 3D GCPs. In relatively flat areas, ortho-rectification is not necessary, but in mountainous areas where
Aerial Photogrammetry: Mapping the World from Above Aerial photogrammetry—once a secret weapon in war—has become an essential tool in shaping the modern world. From mapping battlefields during World Wars to charting entire continents from orbit, this science has seen a dramatic transformation. Today, it plays a critical role across industries, enabling high-resolution data capture for
Sensor Scanner in Remote Sensing What is Sensor Scanner In Remote Sensing, using scanning systems, which employ a Sensor with a narrow Instantaneous Field of View (IFOV) that sweeps over the terrain. Scanning systems can be used on both aircraft and satellite platforms. Types of Sensors Scanning System There are two main modes of scanning
Environment of Remote Sensing Remote Sensing is a play to major role in Environment. It is used to help to protect the resources monitored, mitigate impacts and sustainable use. Environmental monitoring by remote sensing is based on processing data and images acquired by sensors on satellites and other types of platforms. Remote Sensing Application in
