Why was the data set created?

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/CSS; 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.

How was the data set created?

1. From what previous works were the data drawn?

   Zion Ortho-photo (source 1 of 1)

   Horizons, Inc., 19991217, Zion National Park, Utah Orthophotos.

   Type_of_Source_Media: AGFA N400 photographic film

   Source_Scale_Denominator: 40000

   Source_Contribution: Unknown

2. How were the data generated, processed, and modified?

   Date: 2002 (process 1 of 1)

   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.

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

   The thematic accuracy is approximately 81%. Please read the accompanying report or check with Zion National Park for the latest accuracy assessment values.

2. How accurate are the geographic locations?

   (Unknown, Zion ortho-photo basemap, reference Zion ortho-photo metadata.)

3. How accurate are the heights or depths?

   (Unknown, Zion ortho-photo basemap, reference Zion ortho-photo metadata.)

4. Where are the gaps in the data? What is missing?

   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.

5. How consistent are the relationships among the observations, including topology?

   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.

How can someone get a copy of the data set?
