Orthophotos, raw imagery, and scanned aerial photos are common files held here. The most current and high-quality spatial and spectral resolution imagery available was used to facilitate the vegetation classification and mapping of ORCA. The Oregon Geographic Information Council coordinated the acquisition of the project imagery for the state of Oregon in the summer of 2009 through an agreement with the United States Department of Agriculture, Farm Services Agency (FSA), National Agriculture Imagery Program (NAIP). The Oregon Geospatial Enterprise Office (2012) provided digital video disks (DVDs) of the imagery to the SOU research team. The imagery was projected to Oregon State Plane South Federal Information Processing Standards (FIPS) 3602 North American Datum (NAD) 1983 with a spatial resolution of 1.5 feet (international feet = 0.304800 m). The ORCA region imagery was then subset from the NAIP aerial orthophotography acquired for the entire state of Oregon. The 2009 NAIP imagery was collected with a Leica ADS40-SH51 digital camera that recorded 4-band multi-spectral (red, green, blue, and infrared wavelength) images at a spatial resolution of 1.5 feet. The KLMN staff did not make any additional modifications to the delivered NAIP imagery.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. The vegetation map was developed by photographic interpretation of 1993, 1:16,000 scale color infrared photography. Two separate classification systems were used to develop the mapping units. Cultural, disturbed, or unsampled vegetation types used the Anderson Level II classification system. All other vegetation within the mapping boundary used map units derived from the NVCS. A total of 7 Anderson Level II classes and 12 NVCS classes were used. The NVCS classes were combined to form 5 vegetation mapping classes.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Imagery date: 10/25/2001 Area (ac): 307 Area (ha): 124 The polygons on the plastic overlays were then corrected using photogrammetric procedures and converted to vector format for use in creating a geographic information system (GIS) database for each park. In addition, high resolution color orthophotographs were created from the original aerial photographs for use in the GIS. Upon completion of the GIS database (including vegetation, orthophotos and updated roads and hydrology layers), both hardcopy and softcopy maps were produced for delivery.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. NCPN decided to use existing imagery rather than fly new stereo and orthophotography for the TICA vegetation mapping project. NCPN staff and partners worked with 2006 true-color orthophotographs available through the State of Utah to delineate polygons. The acquired photography had relatively low contrast and 1m resolution (i.e., objects smaller than 1m in diameter, including many shrubs, are usually indistinguishable); however, major vegetation boundaries were generally easy to identify.

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 vegetation map consists of 267 polygons comprising an area of 1842.5 ha (4,552.8 ac) (Table 4). Average polygon size is 6.7 ha (16.6 ac). One-hundred-nineteen polygons were 100% dominated by one physiognomic vegetation class. The remaining polygons contain two physiognomic vegetation classes, of these: (1) 59 were 90% dominated by the primary physiognomic class; (2) 34 were 80% dominated by the primary class type; (3) 16 were 70% dominated by the primary class type; (4) 15 polygons were 60% dominated by the primary class type; and (5) 24 polygons had a 50/50 split between the two physiognomic vegetation class types present. Maps are produced in Universal Transverse Mercator (UTM) coordinates (NAD 83) with a 1:24,000 scale and a minimum mapping unit of 0.5 hectares (ha) (1.24 acres (ac)). This vegetation feature class was updated in 2017 to reflect the final Oregon Caves National Monument and Preserve boundary approved by the U.S. Congress on December 19, 2014, which deviated slightly from the original proposed expansion boundary and project area used in the original vegetation mapping effort.

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 vegetation map was developed using a combination of automated digital processing (supervised classifications) and direct image interpretation of high-resolution satellite imagery (Landsat Thematic Mapper and IKONOS). The map is composed of 34 map units derived from the vegetation classification, and is designed to facilitate ecologically based natural resources management at a 1:24,000 scale with 0.5 ha minimum map unit size.
