The Nature Conservancy (TNC) and their affiliates (Association for Biodiversity Information (ABI) and Minnesota County Biological Survey (MCBS) of the Minnesota Department of Natural Resources) provided ecological and vegetation classification support. http://www1.usgs.gov/vip/voya/voya.zip U.S. Geological Survey, Upper Midwest Environmental Sciences Center 200102 data information for Voyageurs National Park USGS-NPS Vegetation Mapping Program Voyageurs NP Vegetation Mapping Project Denver, Colorado U.S. Geological Survey, Center for Biological Informatics The Voyageurs National Park Vegetation Mapping Project is part of the USGS-NPS Vegetation Mapping Program, which is managed by the USGS Center for Biological Informatics. The USGS UMESC provided project coordination and compiled all project data for distribution. The UMESC produced all spatial database sets: vegetation spatial database coverage, observation points, vegetation field plots, accuracy assessment, and various other ancillary spatial coverages. The UMESC also performed the accuracy assessment analysis of the vegetation spatial database coverage, prepared final project documentation discussing methods and results, and provided metadata reports. TNC and their affiliates (ABI and MCBS) provided ecological and vegetation support, vegetation field sampling (plot samples and accuracy assessment), data entry, vegetation analysis, methods documentation, and classification development (including community descriptions) based on the U.S. National Vegetation Classification (USNVC). Voyageurs National Park provided staff to assist in field efforts, boat transportation, and knowledge of the local area. http://www.usgs.gov/core_science_systems/csas/vip/parks/voya.html doi:10.5066/F7F18WQ6 The vegetation spatial database coverage is of Voyageurs National Park and extended environs, covering 156,886 hectares (387,674 acres). Voyageurs National Park comprises 88,244 hectares (218,055 acres) of the total coverage area (56%). Almost 33,000 polygons make up the coverage, each with map unit description and physiognomic attribute information. The database provides crosswalk information to all USNVC floristic and physiognomic levels and several other classification systems (ecological groups/subgroups, Minnesota communities, NW Ontario forest and wetland ecosystems, USGS land use/land cover). A total of 50 USNVC associations make up the vegetation at Voyageurs National Park and environs. With all vegetation types, land use classes, and park specific categories combined, a total of 67 map units define the ground features within the project area. Applicable physiognomic modifiers define each vegetation map unit in more detail about the vegetation structure within a polygon (density, pattern, height, dominance). The spatial database was produced from the interpretation of fall 1995 and 1996 1:15,840-scale color infrared (CIR) aerial photographs. The interpreted data were transferred and automated using base maps produced from USGS digital orthophoto quadrangles (DOQ's) or using Ontario Basic Mapping Series (OBM) topographic maps. About 92% of the spatial coverage is produced using the DOQ-based maps. The finished spatial database is a single seamless coverage. The estimated overall thematic accuracy for vegetation map units is 82.4%. The vegetation spatial database coverage was produced for the Voyageurs National Park Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program. The coverage is also available as 2 separate database sets to reflect the different base map medium used during the automation process; the DOQ-based coverage (Voyageurs National Park, all the environs area within USA, and portions of the environs area within Canada) and OBM-based coverage (remaining portion of environs area within Canada). 19950927 19960913 19960914 19961003 ground condition Complete None planned Voyageurs National Park and environs -93.251019 -92.433491 48.643572 48.280610 None Digital Spatial Database Vegetation Map Vegetation US National Vegetation Classification USNVC National Park None Voyageurs National Park Minnesota USA Ontario Canada None US National Vegetation Classification USNVC Vegetation Plant Community Association Anderson, M., P.

Plot sizes ranged from 20 x 20 m for forests and woodlands to 10 x 10 m for shrublands, herbaceous, and nonvascular vegetation. Plots were placed subjectively in the most representative part of each stand of vegetation. The vegetation was visually divided into strata, and height and cover abundance of each stratum was estimated. Cover of dominant life forms was also estimated to match methods used by the Minnesota Natural Heritage Program survey methods (e.g. total cover of evergreen trees or shrubs was recorded separately from cover of deciduous trees or shrubs (Norm Aaseng, personal communication, 1996). All the species of each stratum were listed (including mosses and lichens) and percent cover estimated using the Braun-Blanquet cover scale. Additional species within the vegetation unit or polygon that occurred outside of sampled plots (generally within 2 m of the plot border) were listed separately. Species that were not identifiable in the field were collected for later identification. Vegetation plot data were entered into the Minnesota Natural Heritage Program's plot database. Species were assigned standardized codes and names based on the PLANTS database (USDA, NRCS 1999). These data were transferred to the PLOTS database developed by the Nature Conservancy (TNC 1997) for final inclusion in this report. For the vegetation analysis, the data were analyzed using the PC-ORD Multivariate Analysis package (McCune and Mefford 1997). The data were analyzed in a series of runs, partitioning the data into smaller sets based on clusters found in the larger data sets, until sufficient resolution was achieved. Multivariate analysis was done using both Non-metric Multidimensional Scaling or NMS (Clarke 1993) and Cluster Analysis. A Bray-Curtis ordination was used as a starting point for the NMS and Ward's Method was used in the Cluster Analysis. These were then reviewed and assessed for perceived environmental gradients (e.g. moisture gradients, peat depth, soil depth, etc.). Indicator Species Analysis (Dufrene and Legendre 1997) was used to identify indicator species and to assess the reassignment of plots into different cluster analysis groups. These groups were compared with the USNVC (Faber-Langendoen et al. 1996, Grossman et al. 1998), as well as to northwestern Ontario types (Sims et al. 1989 and 1997, Harris et al. 1996). Care was taken not to over-emphasize local variations found at Voyageurs compared to more extensive information compiled at the state or regional level. Nevertheless, several types in the USNVC were revised based on these analyses. Plot summaries were produced for each type.

PDF USGS UMESC, TNC and their affiliates (ABI and MCBS) UNIX-ARC/INFO Based on results of a thematic accuracy assessment, the estimated overall accuracy for the vegetation map units is 82.4%. All polygon features were checked for topology and existence of label points using ArcInfo. Each polygon begins and ends at the same point with the node feature. All nodes were checked for error so that there are no dangling features. There are no duplicate lines or polygons. All nodes were snapped together and polygons closed based on a specified tolerance. The tests for logical consistency were performed in ArcInfo. All data within the bounding coordinates are complete with polygons representing ground features at the time of aerial photographs. Each polygon is represented with a single label in the form of a code that represents the map unit and appropriate physiognomic descriptors. A .5 hectare (1.2 acre) minimum mapping unit was applied to all map units, except for the small island categories which are mapped to .1 hectares (.25 acres). The portion of the spatial database that was produced using the USGS 1:12,000-scale orthophoto base maps (hard copy maps plotted from 3.75-minute DOQ's) has a positional accuracy meeting U.S. National Map Accuracy Standards. The portion of the spatial database that was produced using the OBM 1:20,000-scale topographic maps (10 meter contour interval) has a positional accuracy of 1 meter for well-defined features. With most features within the project area not being well-defined (e.g. large forested and wetland areas), positional accuracy is uncertain.

Voyageurs National Park comprises 88,244 hectares (218,055 acres) of the total coverage area (56%). A total of 782 CIR aerial photographs were collected for the project at a scale of 1:15,840. The aerial photograph mission began late September 1995 with the collection of 111 photos, covering much of the northern one-third of the project area. The photo mission was completed late September and early October 1996 with the collection of an additional 671 aerial photographs. A total of 510 aerial photographs were used for mapping. The spatial database reflects conditions that existed at the time the photos were collected. 1995-1996 FIELD RECONNAISSANCE & PHOTO INTERPRETATION: Prior to photo interpretation, field reconnaissance was performed throughout the 1996 field season by the photo interpretation team to learn, test, and verify photo signatures to establish a map classification. Efforts were concentrated in the northern one-third of the project area for which a set of photographs had already been acquired. Ecologists intermittently assisted to assure correct field calls and to verify additional vegetation types as they were encountered. By the end of the 1996 field season, mapping protocols were sufficiently stabilized to permit the aerial photo interpretation team to begin delineating polygons across the northern one-third of the project area. During the 1997 field season, field reconnaissance activities continued, focusing on the southern two-thirds of the project area with an emphasis on photo signatures not readily observed the prior year. Throughout this field process, map unit classes were developed, and a fuller understanding of their linkage to vegetation types was strengthened. Photo interpretation was performed using the 1995/1996 CIR film transparencies (1:15,840-scale). The photographs were cut from rolls and covered with clear acetate overlays. The overlays were registered to the photos. Ground features were interpreted and delineated onto the photo overlays using a Bausch and Lomb Zoom 240 stereoscope over a light table. Each photograph was viewed with its matching stereo pairs so images could be seen in 3-dimensions. To minimize edge distortion, interpretation was focused towards the center of each photograph. Texture, height, pattern, life form, and position in the landscape were all used in the decision process of delineating polygons and assigning map unit codes. Appropriate physiognomic modifiers were added in conjunction with the map unit attribute. An ancillary set of October 1988 CIR aerial photographs (1:12,000-scale) was used to assist in the interpretation process. The 1988 photo set effectively captured fall colors in leaf canopies and revealed distinctions not apparent on the 1995/1996 photo set. A total of 509 aerial photographs were interpreted to produce the spatial coverage. 1996-1998 AUTOMATION & SPATIAL COVERAGE: Bausch and Lomb zoom transfer scopes were used to transfer photo interpreted data to geo-referenced base maps. The transfer process removed much of the aerial photograph's inherent distortion and also tied the interpreted data to real-world coordinates so it could be digitally automated. A total of 51 USGS 3.75-minute DOQ's were used to plot hard copy (film acetate) orthophoto base maps at a scale of 1:12,000. About 92% of the project area was produced with DOQ-based maps, covering the Voyageurs National Park, all the environs area within USA, and portions of the environs area within Canada. For portions of Canada not covered by DOQ's, OBM topographic paper maps at a scale of 1:20,000 were used. The polygons were manually transferred to overlays that were registered to the base maps. Map unit attributes and appropriate physiognomic modifier codes were added to a second overlay that was positioned over the polygon overlay. The overlays were subsequently rechecked for accuracy. Each overlay of transferred data was scanned using a large format sheet fed scanner at a resolution of 400 dots per inch. The resulting Tagged Image File Format images were then converted to a grid using ArcInfo (Version 7.2.1 Patch 2). For data produced with the DOQ base maps, the converted grid was projected to Universal Transverse Mercator (UTM), Zone 15, with datum in North American Datum of 1983 (NAD83). For data produced with the OBM base maps, the converted grid was projected to UTM, Zone 15, with datum in North American Datum of 1927 (NAD27) and later converted to NAD83 once all OBM-based digital coverages were produced and joined. Each individual grid was transformed to a geo-referenced boundary coverage to digitally reference the data to real-world coordinates. In ArcTools, the ArcScan utility was used to trace the referenced polygon data producing an ArcInfo coverage. Each intermediate coverage was edited for errors, assigned attributes to polygons, checked against the hand-transferred overlays for line and attribute errors, and finally joined to produce a seamless spatial database coverage of the vegetation map. The look up table (LUT) was originally produced in spreadsheet format (dBASE IV), and then converted to an ArcInfo table using ArcInfo (Version 8.0.2). The table was merged with the spatial coverage using MAP_CODE as the common attribute item. The merged LUT contains numerous items which provides a set of information for each polygon. For the list of LUT items, refer to the Entity and Attribute Information's Entity and Attribute Overview section within this a metadata report. The finished coverage is single, seamless spatial database of the entire project area. Because 2 procedures were used in the automation process (DOQ-based maps in NAD83, and OBM-based maps in NAD27 later converted to NAD83), the vegetation database was also preserved as 2 separate coverages. 1996-2000 Kevin D.
