BELAIR2013 data acquisition

The BELAIR2013 campaign can be considered as a “rehearsal” or “pilot” campaign for a recurrent BELAIR activity throughout STEREO III, where the defined target areas will be “routinely” extracted on a recurrent basis, taking requirements as expressed at a BELAIR2013 feedback meeting, planned in November 2013, into account to the extent possible.
In-situ data, UAV, APEX and satellite images were acquired by the HESBANIA, LITORA and SONIA teams in July 2013.

Before the BELAIR2013 campaign the radiometric and spectral performance of the field spectroradiometers operated by VITO (last calibration report 20/12/2012), KUL, UCL and VUB were verified in the dark room of VITO in May 2013.  A verification report including recommendations was provided to each operator. After verification of the performance of the field spectroradiometers a measurement protocol developed by VITO was provided to all ground teams involved.

The hyperspectal APEX sensor was calibrated (spectral, radiometric and geometric) at the Calibration Home Base (CHB) hosted by DLR in May 2013.

BELAIR2013 data policy

Satellite data purchased by BELSPO (Pléiades, ASTER, DMC, ...) remain property of BELSPO as stipulated in the contract letters SR/XX/168 (BELAIR HESBANIA), SR/XX/169 (BELAIR LITORA) and SR/XX/170 (BELAIR SONIA)

Airborne APEX & UAV (RGB, thermal, tetracam) imagery acquired over HESBANIA, LITORA and SONIA and in-situ data are released stepwise, depending on user type:

All Remote Sensing (RS) data immediately and free-of-charge available to all participating Users. In-situ field data available upon request to the owner of the data, i.e. to the lab which actually acquired the field data
Two years after delivery of the APEX data to the PI, all BELAIR data available to the entire international Scientific Community. The APEX data was delivered to the PI in January 2014.

All dissemination activities of BELAIR2013 results and data should mention the following sentence “The research pertaining to these results received financial aid by the Belgian Science Policy Office in the frame of the STEREO II programme – subsidy number SR/67/167 (BELAIR2013) and SR/XX/168 (BELAIR HESBANIA) / SR/XX/169 (BELAIR LITORA) / SR/XX/170 (BELAIR SONIA)”


The main aim of the project is to improve the monitoring, steering  and managing of capital intensive perennial fruit orchards by remote sensing.

The LITORA area is situated at the Belgian coastal zone, where the presence of the North sea has a strong influence on the interaction between the people and their environment. 

Activities on the SONIA site focus on spatiotemporal estimation and monitoring of water and energy fluxes in urban areas and forest ecosystems.
