Coastal Normals Information for the Northeast and Mid Atlantic

E3 - Nashville Landsat Land Use/Land Cover Classification

 The Southern Oxidants Study (SOS) conducted a major field research
 campaign in Nashville/Middle Tennessee area in June and July 1994 and
 1995. The goal of this study was to improve scientific understanding
 of the processes that control the production and distribution of ozone
 in the troposphere.

 Landsat Thematic mapper (TM) data (acquired in May 1994) and aerial
 photographs were used to develop a classified image representing 13
 land use/land cover categories for most of the Nashville/Middle
 Tennessee study area. The 13 categories are: conifer,
 hardwood, mixed-hardwood, low-density vegetation, agriculture, bare
 soil, disturbed land, grass, clear cut, high-density developed,
 medium-density developed, low-density developed, and water. The
 classified image was gridded to a 1 square kilometer scale using
 ARC/Info GIS. Total hectares and fractions of each land use/land
 cover category were calculated for each grid cell and county-level
 information (land use/land cover hectares and fractions) was summarized.

 The Tennessee Valley Authority (TVA) was the coordinator for the 1995
 Southern Oxidants Study Nashville/Middle Tennessee Ozone Study. See:

July Total Precipitation

This web application was created for the Hickory, NC Fire Department. The purpose of this web application is to allow the department to easily determine the buildings that are at risk of a specified incident due to their close proximity to buildings that had that given incident. The map enables the user to run a geoprocessing tool that highlights the at-at risk buildings. The tool enables the user to select the incident type as well as the location to examine.

General Population

Summary:Submerged aquatic vegetation (SAV) mapping data were compiled to provide a maximum historical extent of past and present visible SAV habitat within the coastal zone of the Albemarle-Pamlico National Estuary Partnership (APNEP) and southern NC region. Mapping events from multiple years have been included, with varying extents, data collection protocols, and methodology, to encompass all regions of coastal NC. Purpose:These data were created by governmental agencies and researchers to assist in making resource management decisions using a Geographic Information System (GIS). They are intended for planning projects or research that will contribute to better protection and restoration for SAV habitat.

Methodology

Mapping years included and extent

Carraway and Priddy (1983)

Maps of SAV were created from aerial natural color photography accompanied by ground truth data for verification including location and density. Link to report

1981 (May): Bogue, Back and Core sounds

Ferguson and Wood (1994)

Albemarle-Pamlico National Estuary Partnership (APNEP) SAV Partners – SAV 2006-2008 Mapping

Data dictionary available at https://sites.google.com/a/ncsu.edu/dchc-mpo/home The NC State County Boundary GIS data set is to provide location information for the North Carolina State and County Boundary lines with best available information to facilityat planing siting, impact analysis in the 100 counties of NC. Sources for information are NC Division of Transportation, United States Geological Survey and actual field surveys conducted by North Carolina and South Carolina Licensed Surveyors that have been approved and recoded in their respective counties. This file shows some of the boundaries of counties which have a completed boundary survey but the majority of lines have not been surveyed. Also some boundaries cannot be surveyed in cases where boundaries are coincident with river centers. Most of the lines currently are from the DOT county maps which originally come from USGS but might have been updated by the county parcel maps.

Maps have been developed by Clinton Jenkins of the Instituto de Pesquisas Ecológicas (IPÊ). Advice and suggestions came from many colleagues, including Joe Sexton (GLCF), Rob Dunn (NCSU), Stuart Pimm (Duke University), Kyle Van Houtan (NOAA), Lucas Joppa (Microsoft Research), Félix Pharand-Deschenes (Globaïa), and Nick Haddad (NCSU). Producing the biodiversity maps would not have been possible without the enormous efforts contributed to the IUCN, NatureServe, BirdLife International, and the USGS in their ongoing efforts to map the individual distributions of the world’s species. for more info Visit BiodiversityMapping.orgThe brighter purple color on the map represent the areas of highest mammal biodiversity.
