AOI for image pre processing
output format ENVI, GeoTIFF or JPEG
Urbanization Change Map (and classification maps)
Retrieve results directly from the service provider server over FTP

12. Order notes
The AOI for image pre processing is optimized by the pre processing component
Intersection of the datasets and AOI
Result coverage area may be smaller than AOI if a dataset does not cover it entirely
Calibration extent shall be taken into account when defining AOI
+/- 40 degrees from nadir line
Do not select AOI near dataset borders
