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.

Remotely-sensed imagery provides the foundation for mapping vegetation types and other land cover classes. Imagery taken by the GeoEye-1 satellite/sensor was acquired from LandInfo Worldwide Mapping, LLC. The product was delivered as bundled 50 cm panchromatic and 2 meter 4-band multispectral (R, G, B, and NIR) images. The imagery has a positional accuracy of <3 m. Specifications for the GeoEye acquisition included the following: Total area for new collection of 372 square kilometers, 10% or less cloud cover , 0-20 off-nadir angle guarantee, Acquisition dates between late May and late June, 2011 Imagery satisfying the requirements was successfully acquired for the BICA project area on June 15, 2011 and delivered to CSU in July 2011. Each image was delivered as a geo-referenced product mosaicked as a single scene/image. We created a 50 cm resolution pan-sharpened set of multispectral bands to use for interpretation of vegetation. The acquisition provided 4-band imagery during the peak growing season. Additional imagery supplementing interpretation included 30 cm true-color Google Earth/Bing imagery imported to ArcGIS using Arc2Earth™ software and older true-color imagery viewed using the Google Earth online viewer.
