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. Since JODA represented a small site, existing sources of imagery were evaluated and the National Aerial Imagery Program (NAIP) products were found to be adequate. Based on the currentness of the 2009 product, this true-color, 1-meter pixel was accepted as the base imagery. The 2005 true-color, 1-meter pixel product was also used as ancillary data.

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. Natural color imagery was acquired for FOBU on July 21, 2004 and processed into 1:12,000-scale hardcopy prints. The 9-x 9-inch photographs were sent to the USGS, scanned at 1000 dots per inch, and mosaicked into a seamless one-meter digital image orthorectified using a 10 m digital elevation model. NAIP imagery was also obtained as an ancillary dataset for the project area. This imagery was one-meter color-infrared data flown during 2006.

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. Mapping and interpretation of JODA involved a five step process including: (1) field reconnaissance, (2) map class development, (3) image processing and interpretation, (4) draft map validation, and (5) spatial database development. Field reconnaissance was initiated by CTI and NMI staff in 2008 to quickly familiarize the mappers with the vegetation patterns and distribution at JODA. As the classification plot data were acquired later in 2008, feedback on the dominant and characteristic plant species was solicited from ORNHIC ecologists. boundary placement and labeling. Field notes were made directly on vegetation map copies and an additional 70 observation points were sampled to support the notations. Confusing sites were visited including the Picture Gorge area where shadows on the NAIP imagery prevented viewing the distribution of vegetation types. Ground data and ground photographs were collected to insure consistent mapping of confusing sites. Upon return to the office, minor updates of the draft vegetation map were completed prior to the AA task.

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. Two digital orthophoto mosaics, leaf-off (spring) and leaf-on (fall), were created for Thomas Stone National Historic Site. Kucera International acquired color infrared, stereo pair 1:6,000 scale aerial photography for the leaf-off mosaic on February 18, 2002, and for the leaf-on mosaic on November 8, 2002.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. HAFO represented a fairly small and accessible site, no new imagery or aerial photography was deemed necessary for this project. Instead, existing sources of imagery were evaluated and 2 NAIP products were selected to be used as base maps. These included the 2004 and 2006 NAIP products. The 2004 products had 1-meter resolution and were acquired at 1:12,000-scale, which is adequate for vegetation mapping purposes. The 2006 product had 2-meter resolution and was acquired in true-color infrared format. The 2006 imagery was more recent than the 2004 and although it had a coarser resolution, it did highlight all of the recent changes to the landscape such as fires, new roads, tree removals, etc.

Orthophotos, raw imagery, and scanned aerial photos are common files held here.\ Natural color aerial photographs were acquired from three different photo missions between 1995 and 1997. A total of 13 photos along three flight lines were used. The photo missions cover the entire project area, which includes the entire park and environs. Skytech Aero, Inc. (North Little Rock, AR) took aerial photographs for the western portion of the project on August 27, 1995. The photos were taken at a flight height of approximately 13,000 feet with a Jena MRB 15/2323 camera using color negative film. The scale of the 9 x 9-inch paper prints was approximately 1:26,500. Skytech Aero, Inc. (North Little Rock, AR) took aerial photographs for the central portion of the project on September 5, 1996. The photos were taken at a flight height of approximately 12,000 feet with a Jena MRB 15/2323 camera using color negative film. The scale of the 9 x 9-inch paper prints was approximately 1:23,700. Skytech Aero, Inc. (North Little Rock, AR) took aerial photographs for the eastern portion of the project on September 28, 1997. The photos were taken at a flight height of approximately 11,000 feet with a Jena MRB 15/2323 camera using color negative film. The scale of the 9 x 9-inch paper prints was approximately 1:22,000. Two sets of ancillary aerial photography were used as collateral information. The first was a set of CIR paper prints. Intrasearch (12424 E Weaver Place, Ste 100, Englewood, CO 80111) took aerial photographs on August 9, 1983. The photos were taken at a flight height of 12,000 feet above mean ground level with a RC8 camera using Kodak 2443 Infrared film. The scale of the 9 x 9-inch paper prints was approximately 1:24,000. The second ancillary photography was a set of black-and-white paper prints. Rocky Mountain Aerial Surveys, Inc (14 Inverness Drive East, Building G-136, Englewood, CO 80111-6406) took aerial photographs on October 18,1997. The photos were taken at a flight height of 6000 feet above mean ground level with a Zeiss RMKA/15/23 camera using Kodak 2405 XX Black and White film. The scale of the 9 x 9-inch paper prints was approximately 1:12,000. Other source information supplied by the NPS includes (all digital): the park boundary, surficial geology, soils, and noxious weeds. The USGS supplied Digital Raster Graphic data (DRG), Digital Elevation Model data (DEM), and Digital Orthophoto data (DOQ). Slope and aspect data was derived from the DEM.
