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.
Thermal Infrared Remote Sensing What is Thermal Infrared Thermal Infrared (TR) is a energy heat. TR Remote Sensing records the radiant temperature of the object. It was refers to electromagnetic waves with a Wavelength of between 3 and 20 micrometers. Characteristics of TR Most remote sensing applications make use of the 3 to 5 and […]
IKONOS Satellite IKONOS Satellite was launched in September 1999. IKONOS panchromatic Sensor resolution is 1 m, and multispectral scanner resolution is 4 m. The swath width is 13 km at nadir. Accuracy with out ground control is 12 m horizontally, and 10 m vertically; with ground control it is 2 m horizontally, and 3 m
QuickBird Satellite QuickBird Satellite was launched in 2001, by Digital Globe offering imagery for map publishing, land and asset management, change detection and insurance risk assessment. The QuickBird produces sub-meter resolution Panchromatic and Multispectral imagery. The data collection nominal swath width is 16.5 km at nadir, and areas of interest sizes are 16.5 km x
