Description:

Abstract:

The accuracy assessment (AA) for the Waterton-Glacier International Peace Park (WGIPP) was performed to estimate the attribute accuracy of the 1999 vegetation data set for Glacier National Park (Glacier). The 1999 mapping project was performed to describe Glacier's vegetation using the National Vegetation Classification (NVC) scheme. The AA was conducted to locate and document potential thematic errors (i.e., the assignment of an incorrect map class), specifically user's accuracy (suitability for a particular application) and producer's accuracy (conformance to production standards). The AA was performed only on map classes representing NVC natural/semi-natural vegetation types. The Glacier vegetation map was determined to have an overall AA of 87.9% (Kappa index of 87.4%). More detailed results are presented in the WGIPP project report, through the series of contingency tables (<http://biology.usgs.gov/npsveg/glac/index.html#accuracy_assessment_info>). The geographic information system (GIS) data set was developed to show the geographic locations of the vegetation plots which were used during AA project. The data set's attribute table contains background information on each site's id code, location, sampling date, and NVC level 1, 2, and 3 codes and descriptions. The GIS shapefile contains point data features, projected to Universal Transverse Mercator zone 12 mapping coordinates, North American Datum 1983.

Purpose:

The USGS-NPS Vegetation Mapping Program (VMP) is a cooperative effort by the U.S. Geological Survey (USGS) and the National Park Service (NPS) to classify, describe, and map existing vegetation of national park units for the Natural Resource Inventory and Monitoring Program. The goals of the WGIPP vegetation mapping project were to (1) adequately describe and map plant communities of WGIPP and (2) provide the NPS Inventory and Monitoring Program, resource managers, and biological researchers with useful baseline vegetation information.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Several accuracy checks were made against the automated data and the original reports or data sheets, during and after data entry.

Logical_Consistency_Report:

The center of each accuracy assessment plot was estimated using a global positioning system (GPS) receiver or topographic map. The mapping coordinates were recorded on data sheets, which were later entered into a digital database. The database was converted into a geographic information system (GIS) data set, containing point features.

Completeness_Report:

Data forms were filled out for each vegetation plot sampled. Each set of data sheets had a data record recorded for that site in the GIS data set.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The locations of the vegetation plots were recorded using global positioning system (GPS) receivers. If a GPS reading wasn't possible, the location of the vegetation plot was estimated using a topographic map.

The National Elevation Dataset (NED) 1 Arc Second is a raster product assembled by the U.S. Geological Survey (USGS). NED is designed to provide National elevation data in a seamless form with a consistent datum, elevation unit, and projection. Data corrections are made in the NED assembly process to minimize, but not eliminate, artifacts, perform edge matching, and fill sliver areas of missing data. NED has a resolution of one arc-second (approximately 30 meters) for the conterminous United States.

Other_Citation_Details:

This dataset contains the current trail network within Glacier National Park, Montana. These data represent the 2006 revision to official and mapped hiking trails in Glacier. The dataset is based on the initial USGS 7.5 minute topographic mapping that was published in 1966-1968. However, since 1997 Glacier National Park staff have re-mapped 400+ miles of Glacier's 700+ mile trail network using Global Positioning Systems (GPS). Additionally, some rectification of vectors was accomplished using imagery cited in the source information contained in the data set's metadata.

Accuracy Assessment Procedures, NBS/NPS Vegetation Mapping Program

Publication_Information:

Publication_Place: Denver, Colorado

Publisher:

U.S. Geological Survey-National Park Service Vegetation Mapping Program

Other_Citation_Details:

The objectives of this report are to provide the theoretical framework for accuracy assessment and to make initial recommendations as well as alternative procedures for accuracy assessment of the NPS/NBS Vegetation Mapping Project. The procedures must be scientifically sound and yet practical to implement. The core recommendation is to utilize a basic procedure that is statistically rigorous and consistent with traditional methodologies. However, it is recognized that operational constraints may preclude a complete implementation. For this reason, some alternatives for implementing the preferred scenario are provided with the expectation that operational testing during the prototype phase of the project will be necessary to define the utility and reliability of the alternative procedures.

Process_Step:

Process_Description:

Sampling efforts associated with the accuracy assessment (AA) were conducted over a three-year period. To prepare for this project it was decided that sampling should occur in phases. Phase 1 focused on areas that were relatively easy to access, in the northeast portion of Glacier National Park (GNP). Areas selected for Phases II and III were based on a cost-surface analysis. The cost-surface analysis modeled accessibility throughout GNP along a continuum of easy to extremely difficult to access areas. Slopes >65% were considered absolute barriers, along with perennial streams and lakes. Target areas included hiking trails, roads, campsites, and cabins. Areas where trails or roads crossed a perennial stream were considered passable. The final cumulative costs were represented using values that ranged from 0 (very easy to access) to 100 (inaccessible). Due to the difficult nature of accessing the higher values, AA vegetation plot site selection targeted areas with cumulative cost values <25. The only time when values >25 were considered, was to access and evaluate rare map classes.

Process_Step:

Process_Description:

Field crews were provided with listings of GPS coordinates of their accuracy assessment (AA) sites along with field maps. The crews navigated to their sampling sites, then established AA observation plots within the minimum mapping unit (MMU) area. A number of physical characteristics were recorded for each site (e.g., location, slope, aspect, elevation) along with land cover information (e.g., dominant and subdominant vegetation, percent cover). Detailed descriptions on how these plots were established and sampled is available in the Waterton-Glacier International Peace Park mapping project report, available online.

Process_Description:

The field data were then automated, and brought into the software programs ArcView GIS version 3.3 and ArcGIS version 9.x. Information collected in the field was compared to those developed by the photo interpreters (digital data and photo overlays). Results were used to determine; spatial GPS coordinate errors, map automation errors, Unclassified vegetation type on field data sheet errors, incomplete crosswalk between map classes and vegetation type errors, questionable field calls, and inclusion errors (areas missed as they were below the minimum mapping unit). Results of this analysis are available in the Waterton-Glacier International Peace Park mapping project report, available online.
