Free Data Cubes

Welcome to the first issue of the APEX Open Science Data Set!

We are very pleased to make the first APEX (Airborne Prism Experiment)  imaging spectrometer data set available to the remote sensing community. We sincerely hope that this data set will assist you in gaining insights into the huge potential of APEX and help you in assessing its applicability to your domain of spectroscopy research.

Data Acquisition

The APEX Open Science Data Set was acquired during an APEX flight campaign in June 2011. APEX was mounted on a Dornier DO-228 research aircraft operated by Flight Operation and Acquisition of DLR (German Space Agency).

Data were acquired on a clear day from a flight altitude of 4600m above sea level with a heading of 56° in the vicinity of Baden, Switzerland.
