Description:

Abstract:

The accuracy assessment field work was performed in July and August, 1996 to verify the accuracy of the vegetation communities spatial data developed by the USGS-NPS Vegetation Mapping Program for Mount Rushmore National Memorial. 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. The data points were compared to the attributes of the polygon in which they were contained. Attributes of the polygons or accuracy assessment points that did not match were changed during later analysis due to errors in the AA methodology or map attribution errors. A contingency table was completed from the final dataset.

Purpose:

These data were necessary assess the mapping effort in addition to meeting the requirements of the mapping program.

Supplemental_Information:

All codes used in the digital file are referenced by the look-up table that accompanies this file. The look-up table is called veg.lut. It contains both the common name and latin names of the vegetation types.

Attribute_Accuracy_Report:

The attributes for the accuracy assessment were recorded in the field in July and August, 1996. Vegetation associations were identified based on thefield 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 mis-identification of the community on the ground.

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.

Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Methodology_Description:

To assess the thematic accuracy of the vegetation map we conducted an accuracy assessment that allows the user of the digital information an additional perspective upon the data. The final product attempts to achieve the 80% per class accuracy required for this product. Not all mapping units were tested for accuracy. Since the final map contains two separate classification systems, only the mapped areas that fall under the NVCS were included in the accuracy assessment. Areas such as agricultural and undescribed vegetation units and other areas classified using Anderson Level II classification were eliminated from the sample process. Besides excluding the Anderson classified polygons we also Excluded vegetation polygons visited and sampled during either the vegetation description or verification phase that were small enough to confidently say were entirely correct. These were typically riparian polygons in Hell Canyon. These small polygons were eliminated from a site visit in the random selection process but were included in the final accuracy assessment matrix. The remaining areas for sampling were then stratified and sampled according to the number of polygons in each class and the area occupied by each class. Field Procedure: The field crew consisted of two botanists that were Not involved in any part of the previous work on the park. This crew either worked together or separately depending upon local conditions. Both botanists were supplied with a list of points to visit, a field key for map class identification, field data forms, and a GPS to navigate to each site forms. Both crew members worked "blind', meaning that neither one was aware of the existing mapped class designations. Upon arriving at each site, the crews scanned a wide area around the immediate location and observed any local variation in the plant associations. Using the key, the crew then assigned a plant association to the accuracy point. In cases where the variation was significant the crew made a "best fit" judgment to the class name. In addition, other associations in the area and those that might be confused with other plant associations were also noted on each field form. Site Selection: The stratified random selection of accuracy assessment sites was done on the original map classes. The x and y coordinates of each accuracy point were derived from the original vegetation coverage. The coverage was gridded into 50 x 50 meter cells using ArcGrid. A 50-meter grid was chosen because it approximates the minimum mapping unit (MMU) for the project. Using a random number generator, we then re-selected the appropriate number of grids/samples from each class and put them into a separate grid. Additional points were selected for each class over the required number to allow the field crew some latitude in case some sites were inaccessible. The reselected cells where then converted into a point coverage. The x and y coordinate for each point was then transferred to an ascii file. This coordinate file was then used by the field team along with a GPS PLGR unit to locate the position in the field. The point coverage with the accuracy locations and the assigned map unit code are included as a digital coverage. Data Analysis: Due to the inherent heterogeneity of many natural systems, many of the map class determinations to be incorrect. However, when considered in the larger context were correct. To address this issue we attempted to include a 'fuzzy' protocol in analyzing the field accuracy data. For example, when the field crew visited a site they noted not only the appropriate vegetation association designation for the immediate area but also other associations present. When field codes where then compared with the mapped class the point was designated correct if it agreed with any of the associations noted on the field form.

Overview_Description:

Entity_and_Attribute_Overview:

The system 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 hierearchy are based on the species composition of the 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 NBS/NPS mapping efforts.
