The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The final NIOB vegetation map consists of 2,762 polygons totaling 29,081 acres (11,768 ha). Mean polygon size for vegetated types is 8.2 acres (3.32 ha). Of the total area, 20,878 acres (8,449 ha) or 72% represent natural or ruderal vegetation map classes. Agricultural vegetation, such as cultivated crops and pasture, account for approximately 3,267 acres (1,322 ha) or 11% of the total mapped area. Non-vegetated barren land is rare and only accounts for 520 acres (210 ha) or 1.8%. Open water is the most widespread land cover class with an area of approximately 4,415 acres (1,786 ha) or 15% of the total mapped area. Within the total area occupied by vegetation map classes, forest and woodland types were the most extensive (12,278 acres (4,969 ha) or 42%), followed by herbaceous types (7,021 acres (2,841 ha) or 24%), shrubland types (1,134 acres (532 ha) or 4.5%), and sparse types (265 acres (107 ha) or 0.9%).

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. A digital vegetation map was produced as a personal geodatabase using Environmental Systems Research Institute ArcGIS software. The base layer for vegetation mapping was a digital orthophoto mosaic of the park developed by North Carolina State University from color infra-red aerial photography flown for this project in April 2003. The geodatabase includes separate point feature classes for plots, transects, and observations, and polygon feature classes (clipped and unclipped by the park boundary) for vegetation and non-vegetated map classes. The vegetation map consists of 47 map classes, including 15 upland forest and woodland vegetation types, one lichen and sparse vegetation type, 15 riparian vegetation types, two headwater wetland vegetation types, three aquatic feature types, eight cultural and disturbed types, and three transportation feature types.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The final MNRR vegetation map consists of 3,590 polygons totaling 69,011 ac (27,928 ha). Mean polygon size is 12.1 ac (4.90 ha). Of the total area, 37,789 ac (15,293 ha) or 55% represent natural or ruderal vegetation map classes. Agricultural vegetation such as cultivated crops and pasture account for approximately 6,238 ac (2,524 ha) or 9% of the total mapped area. Non-vegetated barren land was rare, only accounting for 45 ac (18 ha) or 0.1%. Developed areas such as open mowed fields, parking lots, buildings, and others account for approximately 1,562 ac (632 ha) or 2%. Open water is the most widespread land cover class, with an area of approximately 23,422 ac (9,479 ha) or 34% of the total mapped area. Within the total area occupied by vegetation map classes, forest and woodland types were the most extensive (17,007 ac (6,882 ha) or 46%), followed by herbaceous types (11,457 ac (4,636 ha) or 31%), sparse types (6,287 ac (2,544 ha) or 16%), and shrubland types (3,038 ac (1,229 ha) or 7%).

This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here. New imagery was acquired for the NIOB mapping project in early October 2015. This imagery was delivered as 30 cm 4-band (RGB and CIR) high-resolution orthoimages. Additional imagery supplementing the interpretation phase included current and historic true-color Google Earth and Bing Maps imagery.

These data were converted from the originally delivered Microsoft Access PLOTs database from the Vegetation Mapping Inventory Project of Niobrara National Scenic River. These comma-delimited data tables contain(s) vegetation mapping plot classification and accuracy assessment data, as well as summary information about the data itself. If a table is empty, then it was empty in the original database.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. A digital vegetation map for GARI was developed as a personal geodatabase using Environmental Systems Research Institute (ESRI) ArcGIS software. The geodatabase includes a point feature class for locations of plots and two polygon-feature classes (clipped by the park boundary and unclipped) for vegetation, including non-vegetated land cover. The vegetation map includes 31 map classes. Upland communities comprise about 86% of the park area and are represented by 13 map classes. Two upland map classes each include patches of two associations, all others represent single associations.
