This dataset contains files created, digitized, or georeferenced by Chris DeRolph for mapping the pre-urban renewal community within the boundaries of the Riverfront-Willow St. and Mountain View urban renewal projects in Knoxville TN. Detailed occupant information for properties within boundaries of these two urban renewal projects was extracted from the 1953 Knoxville City Directory. The year 1953 was chosen as a representative snapshot of the Black community before urban renewal projects were implemented. The first urban renewal project to be approved was the Riverfront-Willow Street project, which was approved in 1954 according to the University of Richmond Renewing Inequality project titled ‘Family Displacements through Urban Renewal, 1950-1966’ (link below in the 'Other shapefiles' section). For ArcGIS Online users, the shapefile and tiff layers are available in AGOL and can be found by clicking the ellipsis next to the layer name and selecting 'Show item details' for the layers in this webmap https://knoxatlas.maps.arcgis.com/apps/webappviewer/index.html?id=43a66c3cfcde4f5f8e7ab13af9bbcebecityDirectory1953 is a folder that contains:JPG images of 1953 City Directory for street segments within the urban renewal project boundaries;

Data created 2005 and updated on a daily basis using GPS and aerial photography. Data part of the State of Tennessee TIPS program for supporting emergency response.

TDEC is continuously striving to create better business practices through GIS and one way that we have found to provide information and answer some question is utilizing an interactive map. An interactive map is a display of geospatial data that allows you to manipulate and query the contents to get the information needed using a set of provided tools. Interactive maps are created using GIS software, and then distributed to users, usually over a computer network. The TDEC Land and Water interactive map will allow you to do simple tasks such as pan, zoom, measure and find a lat/long, while also giving you the capability of running simple queries to locate land and waters by name, entity, and number. With the ability to turn off and on back ground images such as aerial imagery (both black and white as well as color), we hope that you can find much utility in the tools provided.

This data set includes riparian buffer classifications for streams in the Upper Little Tennessee River Watershed that were developed from the corrected streams data set. Riparian buffer classifications were not developed for streams occurring in Nantahala National Forest. The corrected streams data set includes streams mapped by the NC Stream Mapping Program (NCSMP) that have been corrected based on their presence or absence as observed in 2006 aerial imagery. Streams mapped by the NCSMP were downloaded from http://www.ncstreams.org/DataAccess/tabid/257/Default.aspx and corrected using aerial photography for Swain and Macon Counties dated 2006 that were obtained by EEP.

      Four classes of riparian buffer widths were created based on the presence or absence of woody vegetation in the riparian area as viewed in the 2006 aerial photos. Right and left banks were analyzed separately and include the following classes:

      1 = < 30 feet

      2 = 30-100 feet

      3= > 100 feet, and

      4 = underground

      This data set is intended to characterize riparian buffer conditions for streams in the Upper Little Tennessee River Watershed. The riparian buffer classification data set is believed to provide a reasonable basis for generalizing about sub-watershed and watershed conditions. Riparian buffer classification is also one of the key data sets used to determine aquatic function and stream rehabilitation project potential.

      This data set provides an initial estimate of likely riparian buffer conditions, but a field examination of the area in question is recommended if accurate information on the current buffer status of specific reaches or properties is desired.

The imagery posted on this site was acquired following Nashville Tornado in March 2020. The aerial photography missions were conducted by the NOAA Remote Sensing Division. The images were acquired from an altitude of 2500 to 5000 feet, using a Trimble Digital Sensor System (DSS).

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:

This dataset consists of a map depicting the landcover of the Natchez Trace Parkway. The mapping output was created using mosaiced color infrared aerial photography of the Parkway. The map shows the distribution of 18 landcover classes based on the National Vegetation Classification Standard. Ground-based vegetation classification was provided by the National Park Service (NPS). The mapping output delineates grasses, road-developed areas, scrub-shrub, shrubland, plantation, water bodies, areas of white oak, oak, pine-oak, pine-cedar, pine-sweetgum, sweetgum (including sweetgum-oak), scattered trees, swamp forest, irregular classes, aquatic vegetation, invasive species, canopy gaps, and clouds.

Total mapped area includes a 100 m buffer outside the park boundary. 235 digital orthophoto quarter quadrangles (DOQQs) were required to cover the entire 715 km long Parkway. For ease of use, the DOQQs were grouped into 11 mosaics, each covering a section of the Parkway. At the request of the NPS, each mosaic was divided into ten tiles to allow for efficient loading on less robust computers.
