Summary
Hyperspectral Demonstration project objectives were to obtain and make available high spatial and spectral resolution imagery over varied mineral deposit types with typical BC ground conditions.
This hyperspectral imagery is available in either radiance or reflectance values. SpecTIR performed the atmospheric correction utilizing in-house techniques based on the ATCOR4 program. An orthorectification solution is included with each download package.
On-line analysis is available with the Image Analysis Toolbox suite of programs included in the Exploration Assistant map on the MapPlace. The hyperspectral imagery has been added to the collection of Landsat and ASTER images available for analysis through this site. As part of the project two spectral libraries, the USGS Mineral Spectral Library and the John Hopkins University Mineral Spectral Library have been integrated into the site. Spectral Angle Mapper analysis utilizing library spectrum or image spectrum is now available for both ASTER and hyperspectral imagery. A spectrum plotting feature has been added to allow plotting of library or image spectrum for various wavelength ranges and sampled to match ASTER or hyperspectral band configurations.
