The research project was initiated because specific research was needed to investigate the applicability of low altitude multi- spectral scanning for preliminary project development activities faced by ODOT on typical highway projects. In particular, research was needed to measure the effectiveness of low altitude scanning for the detection and mapping of the types of small archaeological sites, potential contamination sites, and environmentally sensitive areas encountered on typical ODOT projects.
