Hyperspec - analysis of handheld spectroradiometer data

There is an increasing use of handheld spectroradiometer data for "ground truthing" of hyperspectral imagery, as well as conducting pilot studies where hyperspectral imagery may eventually be used. There exists a need for standalone software that can be used for organizing, displaying, preprocessing, and analyzing large collections of handheld hyperspectral signatures. The authors of this paper have created a shareware package, HyperSpec, for such tasks. This paper provides details of HyperSpec as well as an example application of the software to an invasive species detection project.
