Grand Teton National Park Vegetation Mapping Project - Spatial Vegetation Data
- Abstract:
-
This metadata is for the vegetation and land-use geo-spatial database for
Grand Teton National Park and surrounding areas. This project is
authorized as part of the USGS/NPS Vegetation Mapping Program. The program
is being administered by the Core Science Systems (CSS) of the
United States Geological Survey (USGS) in conjunction with the National
Park Service (NPS) Inventory and Monitoring Program. The USGS/CSS 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 NPS Inventory and Management 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.
The purposes of this specfic mapping effort are varied and include the
following: 1) provide support for NPS Resource Management, 2) promote
vegetation-related research, 3) provide support for NPS Planning and
Compliance, 4) add to the information base for NPS Interpretation, 5)
provide a vegetation baseline inventory for the Park, 6) provide
information needed for NPS Fire Program, and 7) assist in overall NPS
Operations.

- How were the data generated, processed, and modified?
- Date: Unknown (process 1 of 4)
-
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.
- Date: Unknown (process 2 of 4)
-
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.
- Date: Unknown (process 3 of 4)
-
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 for this
project 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.
- Date: Unknown (process 4 of 4)
-
OTHER DATA: The mapping project and park boundary coverages were
acquired from the Park. A flight line coverage was obtained from the
photography vendor. Field Observation, Plot, and Accuracy Assessment
data point coverages were created by entering points with the 'generate'
command using a text file of points and x-y coordinates.
- What similar or related data should the user be aware of?
- How well have the observations been checked?
The thematic accuracy is approximately 82%. Please read the accompanying
report or check with Grand Teton National Park for the latest accuracy
assessment values.
- How accurate are the geographic locations?
Unknown: Grand Teton Ortho-photo basemap met the National Map Accuracy
Standards, reference the Grand Teton ortho-photo metadata.
- How accurate are the heights or depths?
Unknown: Grand Teton Ortho-photo basemap met the National Map Accuracy
Standards, reference the Grand Teton ortho-photo metadata.
- 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.
- 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.
Are there legal restrictions on access or use of the data?
