Field data for the Vegetation Mapping Inventory Project of Glen Canyon National Recreation Area, Rainbow Bridge National Monument - Open Format Data Package
공공데이터포털
These data were converted from the originally delivered Microsoft Access PLOTs database from the Vegetation Mapping Inventory Project of Glen Canyon National Recreation Area, Rainbow Bridge National Monument. 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.
Geospatial data for the Vegetation Mapping Inventory Project of Glen Canyon National Recreation Area and Rainbow Bridge National Monument
공공데이터포털
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. Aerial photointerpretation was conducted by the Project Manager with the help of an assistant mapper between the fall of 2012 and fall of 2014, using the 2009 1-meter spatial resolution National Agriculture Imagery Program (NAIP) imagery for the Utah portions of GLCA, and the 2010 1-meter spatial resolution NAIP for the Arizona portions of GLCA as the base image layers. The project used the program standard minimum mapping unit (MMU) of 0.5 ha with few exceptions. The majority of the mapping work was performed using ArcGIS editing tools and onscreen, heads-up digitizing, aided by ancillary datasets. Map classes were defined for the project by the primary photointerpreter (PI) with input from the GLCA Chief Scientist. A draft vegetation map and associated spatial database were completed for the Orange Cliffs section of GLCA in the summer of 2014 and for the remainder of GLCA/RABR in the late fall of 2014. Forty-eight map classes represented by 33,691 polygons were developed for GLCA/RABR. A total of 31,058 polygons represent 37 natural or semi-natural vegetation map classes covering 75% of the mapping project area. Eleven additional land use/land cover and geologic map classes describe 2,633 polygons (25% of the area). Average polygon size across all map classes is 23.1 ha (57.2 acres). Blackbrush Shrublands had the highest number of polygons (5,560) polygons covering 14.5% of the total vegetated mapping area.

Trails of Yellowstone National Park

The main Trail Survey took place during the years of 1997-2000. Differentially corrected GPS (Global Positioning System) data were collected primarily on foot for all existing maintained trails and spur trails to backcountry campsites, attractions and buildings within the boundaries of Yellowstone National Park (YNP).The trails that could not be obtained through the GPS or have been rerouted since the survey were acquired through the uses of 1 meter Digital Orthophoto Quarter Quads (DOQQs) and the help of backcountry rangers with knowledge of where the trails are located. There are also associated GPS data for trail bridges, backcountry campsites, patrol cabins and trail surface type. Trail usage data also documented by using visitor ski and bike trail maps. Trails data have been updated since the original survey using information from the Yellowstone Backcountry Office, trails maintenance personnel, best available imagery resources, and GPS data. This layer is a work in progress.
