Synthetic Aperture Radar (SAR) is a specific satellite that can capture imagery in all weather conditions, day or night. SAR sends a microwave radar signal to the earth’s surface to detect physical properties.
Indices are calculated using the multispectral bands. These calculations result in the outputs being in the form of an index with values between 0-1. At the same time, the indices provide additional information about the ground surface being imaged.
Multispectral outputs are made up of bands within the multispectral spectral ranges. The different options include true colour, false colour urban, false colour infrared, and all optical bands.
