Nashville Landsat Land Use/Land Cover Classification from the 1995 Southern Oxidants Study (SOS) Nashville/Middle Tennessee Ozone Study Data Base

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.
