The project is authorized as part of the USGS/NPS Vegetation Mapping Program. The program is being administered by the Biological Resources Division (BRD), United States Geological Survey (USGS). The USGS/BRD is responsible for overall management and oversight of all ongoing mapping efforts. This mapping effort was performed by the U.S. Bureau of Reclamation's (USBR) Remote Sensing and GIS Group, Technical Service Center, Denver, Colorado and NatureServe (formally The Nature Conservancy). The vegetation mapping program is part of a larger Inventory and Monitoring (I&M) program started by the National Park Service (NPS). The purposes of the mapping effort are varied and include the following: Provides support for NPS Resources Management; Promotes vegetation-related research for both NPS and USGS/BRD; Provides support for NPS Planning and Compliance; Adds to the information base for NPS Interpretation; and Assists in NPS Operations. The NPS I&M goals are, among others, to consistently map and document the vegetation of all National Park Service units with a resource component, thereby creating a baseline vegetation inventory. 19990622 ground condition Complete None planned Zion National Park and environs -113.255640 -112.823821 37.532000 37.106056 None Zion National Park Utah Vegetation Land cover and Land use USGS-NPS National Vegetation Mapping Program Plant Association None National Park Service North America United States Utah Zion National Park None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae None Acknowledgment of the USGS and U.S. Bureau of Reclamation Remote Sensing and GIS Group would be appreciated in products derived from these data.

Please read the accompanying report or check with Zion National Park for the latest accuracy assessment values. All polygon features were checked for topology, existence of label points, and label point uniqueness. The labels were checked for correct and complete attributing. All nodes where checked for unintentional lines and to ensure that the polygons were closed. All steps preformed using ESRI ArcInfo commands. All data that could be interpreted from the aerial photos were digitized in accordance with the minimum mapping unit (MMU) of 1/2 hectare. This included selected features that fell into the National Vegetation Classification and the Anderson Level II land use classification. Some classes below the MMU were included, especially water and wetland features and those at the edge of the study area (i.e. cut off by other features and borders). Roads (to visible right-of-way or fence line) and streams/drainages wider than 10 meters were digitized as polygons and attributed accordingly.

Horizons, Inc. 19991217 vector digital data 40000 AGFA N400 photographic film 19990622 19990623 Date of Photography Zion Ortho-photo Unknown MAP CLASSES: Vegetation classification was in accordance with the standards developed under the USGS/NPS Vegetation Mapping Program using the National Vegetation Classification Standard. Field work (collecting plot data) aided in the development of the vegetation classes. In addition, the Park had specific types that were also mapped. PHOTO INTERPRETATION: All map classes were interpreted from 1:12,000-scale, true color aerial photography and 1:12,000-scale true color ortho-rectified photography (ortho-photos). Photo-interpretation used the standard identification features such as tone, texture, color, pattern, topographic position, and shadow. In addition, field sample locations and their vegetation descriptions aided in assigning a map class to each polygon. Photographs were examined using a stereoscope as needed. Linework was created on mylars placed over both the aerial photos and the ortho-photos. GIS PROCEDURES: The linework on the mylar ortho-photo overlays were transferred into the GIS database by one of two methods, either heads-up digitizing or scanning. METHOD I: Heads-up digitizing is a procedure whereby the operator digitizes by hand and eye on a computer terminal screen showing a digital image of an ortho-rectified photo. By looking at similar features on both the aerial photograph and on the orthophoto, the line drawn on the aerial photo overlay is manually transferred to the digital image. METHOD II: The majority of the linework at Zion was transferred via scanning the ortho-photo mylar overlays using a large-format color scanner. Before the mylar was scanned, it was marked with control points that correspond to the 1000-meter grid embossed on the hard-copy ortho-photos. GIS software was then used to convert the scanned files from a raster to vector base using centerline commands. Extensive cleaning, edge matching, and general editing of the digital vectors was completed before polygon topology was created. Labels were created for each polygon and they were attributed with the necessary vegetation information. The entire transfer and editing sequence was automated via in-house Arc/INFO AML programs. OTHER DATA: The mapping project (proj_bndry) and park boundary (park_bndry) coverages were acquired from the Park. A flight line coverage (zion_flight) was obtained from the photography vendor. Field Observation, Plot, and Accuracy Assessment data point coverages (zion_obs, zion_plots, and zion_aa) were created by entering points with the 'generate' command using a text file of points and x-y coordinates. 2002 Dan Cogan Bureau of Reclamation Physical Scientist mailing and physical address
