Patent ID: 8731237

Claim:
A method for detecting assets for disaster relief using multi-spectral satellite images of a satellite, comprising the steps of: A) defining a spectra of interest (SOI) that is indicative of said asset; B) building a reference spectral profile from said SOI; C) extracting test spectra from a spatial region of said satellite image; D) comparing said test spectra to said reference spectral profile using a spectral angle mapper (SAM) tool, said step D) having sub-steps comprising; D1) defining an n-dimensional space according to the number of spectral divisions from said satellite; D2) mapping said reference spectra as an n-dimensional reference vector; D3) projecting said test vector as an n-dimensional test vector; D4) performing the dot product of the result of said sub-steps D3) and D4); and, E) deeming said test spectra to be indicative of a disaster relief asset when the results of said step D) are below a predetermined value.
