Abstract | This dataset encompasses the City of Portland portion of the 2014 LiDAR Survey flown by (WSI) a Quantum Spatial Company (QSI) for The Oregon Department of Geology and Mineral Industries (DOGAMI) with flights occurring from July 2014 through September 2014. The digital elevation model (DEM) represents the earth's surface with all vegetation and man-made structures removed leaving bare points representing just the physical ground surface.
