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. Aerial photography was the foundation imagery for the vegetation map. The photo-bases were from the 1:2,400 scale photo mapping project of Bernalillo County, which also covered PETR. These photos were acquired from March 12 to May 21, 2010 as a digital three-band natural color dataset (with the blue, green, and red wavelength portions of the visible spectrum partitioned into Bands 3, 2 and 1 respectively). As a part of their original processing these files had been ortho-rectified into quarter section photo-tiles with a half-foot spatial resolution, and projected into a Transverse Mercator Projection, NAD83 Datum, HARN spheroid as an .ECW data format. For this project, the particular photo-tiles covering PETR were imported into an ERDAS Imagine (v. 2010) .img format, mosaicked together and re-projected into a UTM projection, Zone 13, WGS84 spheroid, with a 0.16 m spatial resolution.
