The Stormwater Manager's Resource Center is designed specifically for stormwater practitioners, local government officials and others that need technical assistance on stormwater management issues. Created and maintained by the Center for Watershed Protection, the SMRC has everything you need to know about stormwater in a single site.
Hydrographic Survey Database System contains area survey data from the National Ocean Service (NOS), the National Imagery & Mapping Agency (NIMA), and international sources. The NOS hydrographic data base (NOSHDB) comprises the majority of NGDC's area survey holdings and provides extensive survey coverage of the coastal waters and Exclusive Economic Zone (EEZ) of the United State and its territories. The NOSHDB contains data digitized from smooth sheets of hydrographic surveys completed between 1930 and 1965.
