The product generation from hyperspectral sensor data has high requirements on the processing infrastructure, both hardware and software. The Airborne Prism Experiment (APEX) processing and archiving facility has been set up to provide for the automated generation of level-1 calibrated data and userconfigurable on-demand product generation for higher(More)
This paper presents the improvements of an absolute calibration reference system based on simulated TOA BRF time series over bright desert targets. The current work highlights a case study performed over Libya4 demonstrating that it is possible to achieve a mean accuracy of 3% when simulation are compared with calibrated observations. This activity is part(More)
While there is a strong need for hyperspectral imagery, the user-driven requirements are not well defined in view of defined protocols for calibration, acquisition, processing and in-situ measurements in compliance with existing standards. Therefore an analysis was performed in the frame of the EC project HYRESSA, regarding the question “What are the(More)
Since its launch in May 2013, the in-orbit radiometric performance of PROBA-V has been continuously monitored. Due to the absence of on-board calibration devices, in-flight performance monitoring and calibration relies fully on vicarious calibration methods. In this paper, the multiple vicarious calibration techniques used to verify radiometric accuracy and(More)
