This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here.

The most current and high-quality spatial and spectral resolution imagery available was used to facilitate the vegetation classification and mapping of ORCA. The Oregon Geographic Information Council coordinated the acquisition of the project imagery for the state of Oregon in the summer of 2009 through an agreement with the United States Department of Agriculture, Farm Services Agency (FSA), National Agriculture Imagery Program (NAIP). The Oregon Geospatial Enterprise Office (2012) provided digital video disks (DVDs) of the imagery to the SOU research team. The imagery was projected to Oregon State Plane South Federal Information Processing Standards (FIPS) 3602 North American Datum (NAD) 1983 with a spatial resolution of 1.5 feet (international feet = 0.304800 m). The ORCA region imagery was then subset from the NAIP aerial orthophotography acquired for the entire state of Oregon. The 2009 NAIP imagery was collected with a Leica ADS40-SH51 digital camera that recorded 4-band multi-spectral (red, green, blue, and infrared wavelength) images at a spatial resolution of 1.5 feet. The KLMN staff did not make any additional modifications to the delivered NAIP imagery.
