Potential Area for Radiometric Calibration of Satellite Cameras in Indonesia

Cameras on remote sensing satellites must be calibrated in a timely manner to ensure the quality of the images. This calibration process is done before launch and during on-orbit operation. There are several types of on-orbit calibration, some of them require a calibration area that has to be based on several characteristics. This research was conducted to analyze the feasibility of calibration sites in three areas in Indonesia. Those areas are Jaddih Hill, Kupang Cement Mine, and Bromo Tengger Semeru National Park. An objective method to determine the calibration areas was by observing the image's area from the multispectral camera of the LAPAN-A3 satellite (LISA), the multispectral camera of the LANDSAT-8 satellite (OLI), and Google Earth. Furthermore, it was conducted measuring reflectance and analyzing the uniformity of the area by Coefficient of Variation (CV) calculation. The results show that the Jaddih Hill and Kupang Cement Mine according to the requirements as a calibration area at a range of wavelength from 400–900 nm. Meanwhile, Bromo Tengger Semeru National Park is not recommended on those wavelenght.
