Level Ii Pre-processing Concept for the Airborne Prism Experiment (apex)
نویسندگان
چکیده
A concept for the processing and archiving facility for APEX (Airborne Prism Experiment) is defined. A special emphasize is put on the level 2 processing steps which include geometric, radiometric and atmospheric correction of the image data. The presented concept combines these processing steps in a radiometrically logical manner and allows the online production of user required products. The full knowledge about the scanning geometry is used for both radiometric and atmospheric correction. Additionally, the design also foresees possiblities to produce atmospherically corrected images directly from calibrated raw data. The presented concept will allow a fast delivery of high quality data products for the various specific requirements of the APEX data users.

متن کاملA Class-outlier Approach for Environnemental Monitoring Using Uav Hyperspectral Images
In several remote sensing applications, detecting exceptional/irregular regions (i.e, pixels) with respect to the whole dataset homogeneity is regarded as a very interested issue. Currently, this is limited to the pre-processing step aiming to eliminate the cloud or noisy pixels. In this paper, we propose to extend the coverage area and to tackle this issue by regarding the irregular/exceptiona...
