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. Project photography was color-infrared (CIR) stereo-paired diapositives, average scale 1:6,720, flown during September 1995. The project scale was established at 1:6720. The reason for this was the CIR imagery and the orthophotos were not concurrent with one another: the CIR imagery was taken in 1995; the orthophoto was created from imagery taken in 1992.

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 August 27, 2006, 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.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. The vegetation map was created from photographic interpretation of 1996, 1:12,000 scale color infrared aerial photographs (0.5 ha minimum mapping unit). All vegetation and land-use information was then transferred to a GIS database using the latest grayscale USGS digital orthophoto quarter-quads (DOQQs) as the base map and a combination of on-screen digitizing and scanning techniques.

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. The ortho imagery used during mapping at Tonto NM was created from a set of nine color contact prints flown on April 28, 2004. The images were taken by D. Major of Cooper Aerial Surveys of Tucson. The final mosaicked image was created by IntraSearch Inc. Colorado, using 1-meter USGS DOQQ data and USGS 10-meter DEM data to produce a final orthorectified image output of 0.6-m resolution. The reported scale for all images is 1:10,000. All information on processing reported here was taken from the metadata associated with the color mosaicked image. Scanned images were orthorectified in PCI Geomatics OrthoEngine 7 (www.pcigeomatics.com) using a cubic convolution method, with approximately nine ground control points per scan. Accuracy was assessed by overlaying the image onto original DOQQ data in ArcView 3.3.

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.
