What are indices?
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.

What Are Multispectral Outputs?
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.

What Is Archive?
Using a console like EarthCache, archive satellite imagery is a purchasing option for imagery that has already been collected. Archive imagery can be passively collected by satellites that constantly collect over the earth.

What Is Tasking?
Tasking is the act of “ordering” new satellite imagery from a specific satellite. To task a satellite, coordinates of an area of interest (AOI), time frame and interval are sent to the satellite provider.
