Orthophotos, raw imagery, and scanned aerial photos are common files held here. The vegetation map for Rio Grande Wild and Scenic River was based primarily on the 2015 TOP orthoimagery. However, both the 2012 and 2016 NAIP products were used to help delineate confusing upland areas, areas with dark shadows, and rapidly changing areas along the Rio Grande River. In general, the RIGR vegetation map should be considered a snapshot in time directly relating to the 2015 TOP imagery. By comparing the signatures on the imagery to field data, 47 map units (40 vegetated and 7 land-use/land-cover) were developed and used to delineate the vegetation.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The RIGR vegetation map consists of 7,284 polygons totaling 34,506 acres (13,971 hectares) with an average polygon size of about 5 acres (2 hectares). The small polygons are due in part to the detailed mapping, the importance of delineating rare and non-native vegetation types, and the arbitrary splitting of continuous polygons into smaller areas due to RIGR’s unique boundary that follows the active mid-channel of the river. The mapping is also finely detailed since the 2015 TOP imagery was of high resolution allowing for very small stands of vegetation to be accurately mapped. Figure 21 shows an example of the detailed RIGR vegetation mapping centered on the Stillwell and La Linda area.Based on the final vegetation layer, about 3% (1,164 acres) consisted of open water, less than 1% (270 acres) was developed and 96% (33,074 acres) were vegetated. Of the vegetated total, less than 1% (146 acres) was forested or wooded, 65% (22,306 acres) were shrublands, 6% (2,154 acres) were dominated by herbaceous species, and 25% (8,468 acres) contained sparse vegetation. The largest single map unit was the Calcareous Mixed Desert Shrub (S_CDS) type covering 15% (5,245 acres) of the project area. General mapping trends include 71% (24,383 acres) of the project area was mapped as a dry upland scrub or shrubland type, 5% (1,802 acres) was mapped as an upland wash, drainage, or mesic shrub type, and 20% (6,889 acres) was mapped as a riparian type. Non-native vegetation map units were split between 4% (1,411 acres) for herbaceous vegetation and 2% (726 acres) for shrubs.

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. New imagery was acquired for the NIOB mapping project in early October 2015. This imagery was delivered as 30 cm 4-band (RGB and CIR) high-resolution orthoimages. Additional imagery supplementing the interpretation phase included current and historic true-color Google Earth and Bing Maps imagery.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Color infrared, stereo pair, 1:12,000 scale, aerial photography of New River Gorge National River was acquired on March 27, 2003, during leaf-off conditions, by Sanborn Mapping Company, Inc. A digital orthophoto mosaic was produced from 471 color infrared aerial photographs, scanned at 600 dpi with 24-bit color depth. Scanned .tif images of the aerial photographs were imported into ERDAS IMAGINE IMG format where a photo block was created using the airborne GPS and IMU data that Sanborn Mapping Company, Inc. supplied with the aerial photography.

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.

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
