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 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.

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. In late May and June of 1997, after a preliminary vegetation map had been prepared by the photointerpreter, a map validation step was performed in which further data were collected to obtain more information on the vegetation types and to better correlate the vegetation with the signatures on the aerial photographs. Sampling was conducted at points selected by the photointerpreter based on stratified random design in which more extensive vegetation types were allocated more points. This resulted in the collection of 36 observation points. At each point, the dominant species in each vegetation stratum were recorded with an estimated cover class. These extra points gave a better understanding of the variation within vegetation types and allowed sampling of three types that had not been found in the previous field season.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Large scale final map products were created within ArcMap and designed to show both the orthophoto coverage and the vegetation maps. For the vegetation maps, colors were assigned and the polygons labeled with the dominant vegetation and modifier and, where present, the second vegetation and modifier. For the orthophoto maps, the photos were simply plotted at the same scale and area coverage as the vegetation maps. Additional planimetric map data included roads, trails, hydrology, boundaries and a UTM coordinate grid. Legends are designed to provide full definitions of the vegetation and buffer classes and modifiers, as well as information about the park, map projection, data sources and authorship (Figure 19). All maps are projected to the Universal Transverse Mercator Coordinate System, North American Datum of 1984, in the local zone for the specific park.

These data were converted from the originally delivered Microsoft Access PLOTs database from the Vegetation Mapping Inventory Project of Oregon Caves National Monument. These comma-delimited data tables contain(s) vegetation mapping plot classification and accuracy assessment data, as well as summary information about the data itself. If a table is empty, then it was empty in the original database.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Field reconnaissance is intended to familiarize the photo interpreter with the Monument, patterns of vegetation distribution, and environmental factors. During map class and attribute development, the mapping ecologist uses all available information, professional experience, and an inspection of the aerial imagery to develop map classes and appropriate attributes. Mapping is the process during which the photo interpreter uses field data, field notes, and characteristic photo signatures to draw consistent, homogenous polygons on the base photography. During spatial database development, attributes (e.g., vegetation height, land use category) and ancillary datasets (e.g., photos, map class descriptions) are linked to each point or polygon in the spatial layer. Because TICA is a small park, the first three steps were accomplished simultaneously during the plot data collection visit in June 2007.
