- Abstract:
-
The accuracy assessment field work was performed
in May, 1997 to verify the accuracy of the
vegetation communities spatial data developed by
the USGS-NPS Vegetation Mapping Program for Tuzigoot National Monument.
The data points were randomly distributed stratified according to
vegetation association over the project area
according to protocols developed by the Program.
Points were located by GPS navigation and the
community information was collected at the point,
without knowledge of the attributes of the
vegetation spatial data.
- Purpose:
-
To verify the accuracy of the mapped vegetation
communities at Tuzigoot National Monument

- Attribute_Accuracy_Report:
-
The attributes for the accuracy assessment were
recorded in the field in May, 1997. Vegetation
associations were identified based on the field
key and plant identification. If additional
communities were found within a 50 meter radius of
the plot center, they were recorded as well.
During the analysis, it was concluded that some
attributes were in error and changed to match the
mapped attributes. This was done by examination
of the aerial photographs under stereoscopic view.
The attributes were in error due to 1) spatial
error in the GPS derived coordinates (4-8 meters),
2) change of vegetation community due to temporal
changes, or differences between observation team identifications.
- Logical_Consistency_Report:
-
All attributes are codes that correspond to
vegetation communities and have been checked for
typographical and logical errors.
- Completeness_Report:
-
All points were collected and analyzed. Several
points fell outside the mapping area, so were
discarded.

X,Y UTM coordinates representing each of the 35 plots were collected by
P-code PLGR (Precise Lightweight GPS Receiver) receivers, with an
accuracy ranging from +/- 10 m. to +/- 30 m. based on 60 second
averaging at each point.

- Methodology_Description:
-
Data points were located by use of a PLGR GPS
receiver. Vegetation communities were identified
on the basis of a dichotomous field key and plant
species present.

- Methodology_Description:
-
Accuracy assessment points were compiled into an
ARCINFO point coverage and intersected with the
vegetation community coverage. The resulting INFO
file was exported into a text file, imported into
a spreadsheet, and the attributes from the
accuracy assessment and the spatial data were
compared. If the attributes did not compare, an
analysis of the mismatch was made and either the
AA attribute or the map attribute was changed
based on identification of the community on the
aerial photo.

The National Vegetation Classification Standard is
organized hierarchically to support conservation
and resource stewardship applications across
multiple scales. The upper levels of the hierarchy
are based on the physical form or structure of the
vegetation (physiognomy) and have been refined
from the international standards developed by the
United nations Educational, Scientific, and
Cultural Organization (UNESCO). The two most
detailed levels of the hierarchy are based on the
species composition of existing vegetation
(floristics) and reflect the phyto-sociological
standards that were originally developed by
European ecologists. The vegetation classification
is continually advanced through the collection and
analysis of new field data and will be greatly
strengthened during the course of the USGS-NPS
mapping efforts. Data file attributes include
species, alliance, community element, and land cover.
