ABSTRACT
This dataset is Elevation-derived hydrography (EDH) for the 300294 PA_LakeErie_B24_H project covering work unit PA_LakeErie_1_B24. The hydrography layer contains line features representing stream rivers and polygons representing waterbodies. The EDH was derived from 1 meter lidar Digital Elevation Models. This dataset was created to meet the requirements of the USGS Elevation-derived hydrography specification, https://www.usgs.gov/core-science-systems/ngp/ss/elevation-derived-hydrography-specifications. 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).
