Hyperspectral Data Processing and Analysis
- Hyperspectral data are analyzed using a standardized
approach based on partial spectral unmixing. VNIR/SWIR HSI data are
converted to apparent reflectance using an atmospheric model. MWIR
and LWIR HSI data are converted to emissivity using temperature-emissivity
separation algorithms. Atmospherically corrected data are
spectrally
and spatially reduced to a limited number of spectral endmembers
generated internally from the HSI data, and image maps of endmember
locations and abundances are produced. Alternatively, library
endmembers are used to perform mapping of known materials. Results
can be provided in GIS-ready form.

- Other services offered include custom reflectance/emissivity
correction of HSI data, image georectification and mosaicking and
production of softcopy and hardcopy image maps at specified scales and map
projections.
- Examples of data types supported include AVIRIS, HyMap,
Hyperion, Sebass and HIRIS. Other HSI data types can be accommodated
on request.
