LANDNET SITES (CEOS Reference Sites)

The LANDNET Sites are a set of Land Equipped Sites (LES) endorsed by CEOS as standard reference sites for the post-launch calibration of space-based optical imaging sensors. During the CEOS IVOS-19 Meeting, held in Phoenix AZ, eight instrumented sites have been selected.

These instrumented sites are primarily used for field campaigns to obtain radiometric gain and these sites can serve as a focus for international efforts, facilitating traceability and cross-comparison to evaluate biases of in-flight and future sensors in a harmonized manner^[1].
