The National Hydrography Dataset (NHD) high-resolution map layer is complete for Indiana. “This is a great development, but is only the first phase. We now hope to find ways to improve, maintain, and expand use of the data,” says David Nail, USGS Geospatial Liaison for Indiana. The National Hydrography Dataset is now available in a new database design that allows better web-based access and query, as well as truly seamless data that can be downloaded in various extents. The new database design provides a distribution format called NHDinGEO. Data requests in NHDinGEO can be extracted by subbasin, county, congressional district or by topographic map quad.
