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 provided by the National Park Service for this project. These photos were acquired on 11/13/2003 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). The photos had been ortho-rectified into a Universal Transverse Mercator Projection, NAD83 Datum, Zone 13. They were mosaicked into two separate images representing the main park area and the headquarters area. The resulting photo-mosaic provided a geometrically accurate map of ELMA with high spatial detail. The radiometric fidelity was consistent throughout. Unfortunately, visible wavelengths tend to be highly correlated with limited spectral information. In this case, except for discriminating between the lava and the non-lava covered landscapes, the imagery was relatively spectrally featureless.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Photointerpretation was done using 9 × 9-in, 1:12,000-scale, true-color photographs. Mylar overlays placed on each aerial photo allowed the project team to make notes and delineate polygons. At this stage of interpretation, a stereoscope was used to help recognize complex photo signatures and three-dimensional features. No attempt was made to label polygons at the initial stage of photointerpretation. Polygons were delineated using homogenous ground features as a mappable unit. These drawn polygons were later revisited after field-data collection in order to assign a map unit and other polygon attributes.

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 imagery we used was acquired by Digital- Globe Inc.’s Quickbird satellite on December 3, 2007, as a new, tasked acquisition for this project. Image preprocessing and initial interpretation to the formation level were done at the Arizona Remote Sensing Center, University of Arizona. The imagery product purchased was the “Ortho-ready Standard” bundle of four spectral bands (blue, green, red and near-infrared) at 2.4-m spatial resolution, plus the broadband panchromatic data at 0.6-m resolution. This imagery is intended to be orthorectified by the user and is only coarsely geo-registered, with a nominal spatial accuracy of 23 m CE90—meaning that 90% of features in the imagery must be within 23 meters of their true location on the ground.

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 digital ortho-photography was the foundation imagery for map development. For Abó, the photography was acquired on April May 15, 2002 at a scale of approximately 1:3,000; for Quarai and Gran Quivira it was flown on April 2, 2003 at scales of 1:3,600 and 1:3000, respectively. The 2002-03 digital imagery has a base pixel resolution of 1.0 m. We also made use of statewide 1-meter resolution, true-color imagery from 2005 that became available in 2006 through the New Mexico Resource Geographic Information System

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. A set of CIR aerial photographs was collected on October 4, 2006. This photo mission was funded by the NPS VIP, and supervised by GLKN staff. This set of photography covered the entire GRPO vegetation mapping project extent at 1:12,000-scale and was the primary imagery used in photointerpretative mapping. In support of mapping from the CIR photos, we used a set of TC aerial photographs (1:8,000-scale) that was collected May 2, 2003, providing deciduous leaf-off viewing of the entire extent. This photo mission was funded by GRPO and supervised by GLKN staff. Having the TC photos gave interpreters a definite advantage in determining evergreen tree and shrub components within forest communities otherwise obscured by deciduous tree canopy on the fall-season CIR photos, thus giving credence to Avery’s statement regarding lack of a single all-purpose film emulsion. To assure stereo viewing and full aerial coverage, aerial photo missions were planned with a 60% forward-lap and 30% side-lap. Contact prints of both CIR and TC photo sets were produced for fieldwork use by mappers and vegetation crews. Diapositives of the CIR photo set were produced for photointerpretative mapping.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Color infrared (CIR) aerial photographs of the park at 1:12,000 scale was acquired by Aero-Metric, Inc. on May 11, 2011. These photos were scanned and converted to digital orthophotographs at 0.3- meter (1 ft) resolution before they were delivered to the National Park Service. Digital orthophotographs and hardcopy photographs in both film transparency and paper print formats were provided to the University of Georgia Center for Geospatial Research. A total of three photos in one flight line was required to cover Castillo de San Marcos National Monument
