Appalachian Trail Environmental Monitoring- Streams and Waterbodies of the AT Corridor (broadly defined)
Content Description
Abstract:
This dataset was created for the Appalachian Trail Environmental Monitoring Community project funded by the National Biological Information Infrastructure-Southern Appalachian Information Node (NBII-SAIN) at the University of Tennessee in Knoxville, TN. The goal of the project is through collaboration among willing partners, to establish a 2,167 mile continental transect dedicated to environmental inventory and monitoring (I&M) via the Appalachian Trail (AT) Corridor. This goal will be realized by the creation of an internet Community on the USGS NBII Portal concerning the environmental I&M on the AT Corridor. A database of publicly available key ecosystem data themes was defined, and the data harvested from various sources. The purpose of these compiled data sets is to place the state of the environment along the A.T. in a continental-scale context in one centralized location. With assistance from the USGS Eastern Region Geospatial Program Office, these datasets will be implemented via an online data viewer located on the USGS CUES website.
This dataset contains data on the polygon and line water features of the AT Corridor. The file was produced by joining the individual State hydrography layers from the 1:2,000,000- scale Digital Line Graph (DLG) data produced by the USGS. This data set was formerly distributed as Hydrography Features of the United States.
Purpose: To place the state of the environment in a continental-scale context. This project supplement will hopefully prove to be an impetus for collaboration and discussion among key AT scientists involved in environmental I&M.
