In order to evaluate KOrea Multi-Purpose SATellite (KOMPSAT) application products and develop the multi-sensor data application technologies, the product validation site will be established by Korea Aerospace Research Institute (KARI).

However, high resolution mapping for forest type and vegetation index, sometimes hyper-spectral data are needed such as the Compact High Resolution Imaging Spectrometer (CHRIS) data.

Project for On Board Autonomy (PROBA) CHRIS data will be used to generate the high spatial and high spectral resolution thematic maps and develop the multi-sensor data processing algorithms with KOMPSAT data.

Also, CHRIS hyper-spectral data will be used to evaluate KOMPSAT application products such as land-cover/use classification, high resolution mapping, etc.

Synergistic use of KOMPSAT and PROBA data
