- Abstract:
-
The accuracy assessment field work was performed
in July - September, 1998 to verify the accuracy of the
vegetation communities spatial data developed by
the USGS-NPS Vegetation Mapping Program for Isle Royale
National Park 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 Isle Royale National Park

- Attribute_Accuracy_Report:
-
The attributes for the accuracy assessment were
recorded in the field in July - September, 1998.
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.

- 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.
