The Upper White River study area landscape metric maps provided in this section are based on the status of conditions in the early portion of the 1970s, 1980s, 1990s, and 2000s (see maps and metadata for additional information). Land-cover maps are provided for the dates indicated, and have been produced to specifically address the analysis questions of the stakeholders in the region (i.e., with regard to the potential interactions between surface water-quality and the spatial and temporal distribution of urban and agricultural areas). For this reason, the number of land-cover classes was intentionally kept to a minimum in order to address the specific questions of stakeholders, and to provide maximum land-cover classification accuracy. Initial land-cover validation sampling indicates an overall accuracy of the 2003 land-cover map in excess of 95% (N=73). Water-quality indicator maps in this browser are based upon geospatial statistical analyses of the land-cover data and the water-quality sampling data among the 244 subwatersheds in the study area.
- Overview of Land-Cover Types
- Examples of urban land-cover are urban centers and small rural towns.
- Examples of the agricultural/grassland land-cover are pasture, a row crop field, a golf course, or any other area of herbaceous vegetation.
- Examples of forest land-cover are nature reserves and woodlots.
- Examples of water are streams, rivers, lakes, and ponds.
- Examples of barren land-cover are a gravel pit and a sandy beach.
