Description: This dataset is Elevation-Derived Hydrography (EDH) for Hamilton County located in Indiana. The EDH contains line features representing streams and rivers and polygons representing waterbodies. The EDH was derived from a 2-foot lidar-derived Digital Elevation Model (DEM), acquired in 2024. This dataset meets the requirements of the USGS Elevation-Derived Hydrography Data Acquisition Specifications (2023 rev. A2) and READ Rules. The line features contain Elevation Class (EClass) codes useful for hydro-enforcement, including culvert identification. Feature Class (FClass) and Feature Codes (FCodes) are hydrography codes compatible with the National Hydrography Dataset (NHD), now retired.
