NRL Hyperspectral Imagery Trafficability Tool (HITT): Software andSpectral-Geotechnical Look-up Tables for Estimation and Mapping of Soil Bearing Strength from Hyperspectral Imagery

Abstract : This report provides details of a new hyperspectral exploitation tool for developing trafficability special maps from hyperspectral imagery. This new tool, known as the NRL Hyperspectral Imagery Trafficability Tool (HITT), is packaged as a plug-in to the commercial software package ENVI/IDL. HITT is one of several tools being developed and validated by NRL to support coastal characterization from spectral region imagery. This report provides a step-by-step description of the operation of HITT, working through specific examples that begin with a hyperspectral data cube and end with a special map of estimated trafficability in a coastal region. The basis of this new product is a set of spectral-geotechnical libraries and models developed during remote sensing and calibration/validation campaigns conducted by NRL and collaborating institutions in four different coastal types.
