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.
Satellite Imagery Satellite Imagery/images are Data collected by Satellites to Earth’s Surface and Ocean. Satellite imagery is used for Weather analysis and forecasting, and also Satellite image analysis Land cover/ use.

Change Detection in Remote Sensing using Erdas Imagine In this Tutorial, Learn Change Detection in Remote Sensing using Erdas Imagine Software. What is Change Detection? Change Detection is a process that measures a particular area that has changed between two or more periods. It has been widely used to evaluate shifting agriculture, deforestation, urban growth,
Unsupervised Classification in Erdas Imagine Unsupervised Classification is called clustering because it is based on the natural groupings of pixels in image data when they are plotted in feature space. Unsupervised Training The Unsupervised training is more computer-automated. You can specify some parameters that the computer uses to uncover statistical patterns that are inherent in the
Supervised Classification in Erdas Imagine Supervised classification uses image pixels representing regions of known, homogenous surface composition ‘training areas’ to classify unknown pixels. A Supervised Classification describes information about the data of land use as well as land cover for any region. Soil type, Vegetation, Water bodies, Cultivation, etc. Supervised Training Supervised training is closely
Aerial Photography What is Aerial Photography? The Aerial photography, a technique of capture photographing to the Earth’s surface. Aerial photography is the taking of photographs helps with an aircraft, helicopters, balloons, blimps, dirigibles, rockets, parachutes, etc. In recent times, use ‘Drone’ to capture Aerial Photographs. In Photographs the locations of which determined by ground-surveying techniques this technique known as
