13. AISA software

14. Aisa Operating Software RS Cube • All the AISA systems use • Windows-based flight operations • software RSCube to • Control hardware like image (frame) rate and exposure time. • Display images, GPS/INS status, and other information in real-time for monitoring the progress of data collection

15. Aisa Operating Software RS CUbe • All AISA systems can be used in two operating modes: • A: full hyperspectral data acquisition • B: multispectral data acquisition at programmable wavebands Band files are created with AISA Bandage

16. Caligeo Software CaliGeo is an easy-to-use, GUI-based, interactive software package (stand alone or Envi plug-in). It allows you to fine tune your images and turn your raw AISA data into final useable products. With CaliGeo you are able to perform Radiometriccorrection Geo-referencing (Geometriccorrection) CaliGeo also provides the tools to automatically analyze and correct boresight errors caused by mechanical tolerances between: head and GPS/INS VNIR and SWIR sensor heads

17. Dems A digital elevation model (DEM) defines the ground elevation for every single ground point, independently of the other points. Using a DEM is supported in CaliGeo. However, it is up to the user to provide ENVI-readable DEM data for the entire image area in a suitable format with a proper resolution If the DEM does not cover the image area and CaliGeo needs values outside the DEM, then CaliGeo will use the nearest DEM pixel on the edge of the DEM. There are no size restrictions for the DEM file. The file can cover a larger area than the raw image. The DEM file must be in ENVI readable format (1 channel grayscale raster data) To achieve a good rectification result, the ground resolution of DEM should reflect the height differences in ground (e.g. If having tall buildings etc. in the image a good ground resolution is recommended)
