Description: This feature class describes properties listed on the National Register of Historic Places, classified as historic buildings, and depicted as points. The National Register of Historic Places requires the submission of a single UTM coordinate pair for properties under 10 acres. A building, such as a house, barn, church, hotel, or similar construction, is created principally to shelter any form of human activity. A building may also be used to refer to a historically and functionally related unit, such as a courthouse and jail or a house and barn. Buildings include: houses, barns, stables, sheds, garages, courthouses, city halls, social halls, commercial buildings, libraries, factories, mills, train depots, stationary mobile homees, hotels, theaters, schools, stores and churches. Attribute data in this dataset are intentionally limited to those necessary for spatial data maintenance and feature level metadata necessary to document the lineage of the geography itself. Data from external database systems, such as the National Register Information System, are intended to link with these data to provide basic feature attributes. The means to maintain unique identifiers for each historic site (CR_ID), Survey_ID, as well as unique geometries associated with that feature (Geometry_ID) are through the use of Globally Unique Identifiers (GUIDs) assigned by the database. Information about the genesis of individual points is documented by feature level metadata fields in the spatial attribute table.
Description: This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.
Description: For watersheds in the OKI region, the Watersheds Layer serves as a spatial-reference framework for water quality data and other datasets in the Stream Database. Watershed boundaries and Hydrologic Unit Codes (HUCs) were acquired from the Watershed Boundary Dataset (WBD), which delineates surface water drainage areas based on land area and topography. The HUC system provides a tiered approach to classifying and identifying these drainage areas.For its four Ohio counties (Butler, Clermont, Hamilton and Warren) OKI obtained most of the watershed data and water quality assessments from the 2010 Ohio Integrated Water Quality Monitoring and Assessment Report (Ohio Environmental Protection Agency, Division of Surface Water, 2009-10). This includes evaluations of aquatic life uses, recreational uses, public water sources, and human health risks related to fish consumption. For each impaired watershed, the Watersheds Layer notes the status of a Total Maximum Daily Load (TMDL) study, which determines the total maximum daily loads of selected pollutants that can enter an impaired stream without ruining efforts to improve stream health. The layer also notes significant stewardship groups that have been organized to improve water quality in each watershed. OKI’s Stream Database Glossary defines the widely accepted concepts, specialized terms and acronyms associated with watersheds and water quality.
