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. Existing sources of imagery were evaluated for vegetation mapping and geodatabase development for CIRO. Among the current sources of imagery were NAIP products from which the 2006 1-meter resolution product was determined adequate for mapping. The 2006 NAIP imagery was originally used to delineate obvious land-use and physiognomic boundaries. However in 2009, NAIP acquired new 1-meter resolution (true-color format) for the entire state of Idaho. Following examination, the 2009 NAIP imagery for Cassia County, Idaho was deemed superior in color and was more recent so the vegetation mapping was switched from the 2006 imagery to the 2009 product (Figure 12). All previous land-use and physiognomic linework was updated and the final map product is based solely on the 2009 NAIP ortho-imagery.

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. One complete set of aerial photography was provided for the project, including both a set of prints and diapositives. The specifications for the aerial photography are listed below: Color infrared photography (CIR) Flown October 29, 1996 - (height of the leaf change) Nominal scale - 1:6,000 (Nominal refers to the photo scale variability within each aerial photo and across flight lines. In this case the photo scale ranged from approximately 1:5,800 to 1:6,200) Approximate photo size - 9" x 9" Overlap between photos and across flight paths met the standards for photo interpretation using a mirror stereo scope. (Approximately 60% between photos and 10% - 20% between the flight lines)

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. Vegetation and land use were interpreted to as detailed a level as possible from high-resolution, 9” x 9” stereo pairs of 1:12,000-scale true color aerial photography. Polygons representing vegetation or land use map classes were delineated on Mylar overlays on aerial photographs (where signatures were confusing) and with the heads-up digitizing technique (where signatures had high contrast), then transferred to a spatial database. The project used the national program standard minimum mapping unit of 0.5 ha with few exceptions.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. The initial base map layers were developed using the 2 m resolution color aerial orthophotos, since they had the highest spatial resolution. The regions were designed on their shared physiography: Eastside, Westside, Riverside, USFS, and Tsankawi sub-units. The vegetation map was developed using a combination of automated digital processing (supervised classifications and image segmentation) and direct image interpretation of high-resolution color and color infrared aerial orthophotography in combination with satellite imagery (Landsat Thematic Mapper).

Orthophotos, raw imagery, and scanned aerial photos are common files held here. GRBA base map imagery included a 4-band, 1-meter resolution, 2007 Digital Globe product and a 4-band, 6-inch resolution product acquired in June and July 2007 by Digital Mapping, Inc. (DMI) for the Southern Nevada Water Authority. Interpretation and mapping of the vegetation began using a four step process involving: (1) preliminary image classification and segmentation, (2) photo-interpretation and digitizing, (3) ground-truthing of the mapped data, and (4) map refinement and finalization.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Photointerpreters delineated initial polygons through manual interpretation of 2003/2004 1:12,000-scale true color aerial photography supplemented by occasional computer screen digitizing on a mosaic of digitized aerial photos. These polygons were labeled with base map classes during photointerpretation. Field visits verified interpretation concepts.

Vegetation and land use were interpreted to as detailed a level possible from high-resolution, 9” x 9” stereo pairs of 1:12,000-scale true color aerial photography. Polygons representing vegetation or land use map classes were delineated directly on-screen through heads-up digitizing using ArcGIS editing tools and transferred to a spatial database. The project used the program standard minimum mapping unit of 0.5 ha with few exceptions.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Several imagery datasets were available for the mapping project. Table 7 lists the types of imagery used in the LEWI mapping project, including the date the imagery was produced and the source of the data. Landsat satellite imagery was acquired from GLOVIS (http://glovis.usgs.gov/). SPOT 4 imagery was downloaded from EarthExplorer (http://edcsns17.cr.usgs.gov/NewEarthExplorer/). Landsat imagery at 30 m resolution consists of 7 bands: 3 visible, 2 mid-infrared, 1 shortwave infrared and 1 thermal band. SPOT 4 imagery consists of 4 bands: 2 visible (10m), 1 shortwave infrared (10m), and 1 mid-infrared (20 m). Imagery used was from the summer 2008 (Landsat) and late fall 2010 (SPOT 4) to provide a phenological contrast useful in differentiating vegetation types. Every homogeneous vegetation type has a unique reflectance which is referred to as a signature. This unique signature is often more apparent and distinct in the infrared wavelengths outside of the human eye visible spectrum, enabling a remote sensing expert to use these unique satellite signature snapshots in time to differentiate various vegetation types.
