	Nautical Charting Search for Data \| View Topic \| Related Data Sites Nautical charts contain information about the nature and form of the coast, the depths of the water and general character and configuration of the sea bottom, locations of dangers to navigation, the rise and fall of the tides, locations of navigation aids, and characteristics of the earth's magnetism. Sample data in this topic include: Electronic Navigational Charts (ENCs) Raster Navigational Charts (RNCs) Wrecks and Obstructions Coast Pilot Maritime Boundaries (top)

	Bathymetry/Topography Search for Data \| View Topic \| Related Data Sites NOS conducts hydrographic surveys to measure the depth and bottom configuration of water bodies, to produce the nation’s nautical charts and ensure safe navigation. Sample data in this topic include: Hydrographic Surveys & Descriptive Reports NOAA's Estuarine Bathymetry (top)

	Shoreline Search for Data \| View Topic \| Related Data Sites The United States has approximately 95,000 miles of coastline. One of the NOS missions is to survey these coastal regions and to provide the Nation with accurate, consistent, up-to-date national shoreline. Sample data in this topic include: High Resolution Shoreline Shoreline Surveys & Manuscripts LIDAR (top)

	Geodetic/Global Positioning Search for Data \| View Topic \| Related Data Sites NOS maintains the National Spatial Reference System (NSRS). This is a consistent national coordinate system that defines position (latitude and longitude), elevation, distance and direction between points, strength of gravitational pull, and how these values change over time. Sample data in this topic include: Continuously Operating Reference Stations (CORS) Geodetic Control Points Aeronautical Data (top)

	Tides/Currents Search for Data \| View Topic \| Related Data Sites NOS has been monitoring water-level variations for over 100 years. Water-level data is used for a variety of practical purposes, including hydrography, nautical charting, maritime navigation, and coastal engineering. Sample data in this topic include: Water Levels Currents (top)

	Remotely Sensed Imagery/Photos Search for Data \| View Topic \| Related Data Sites NOS acquires remotely sensed imagery and precision aerial photography for different habitat mapping and shoreline delineation projects and to support emergency response efforts. Sample data in this topic include: Coastal Photography IKONOS Imagery LIDAR Post-Storm Hurricane Photography (top)

	Marine Boundaries Search for Data \| View Topic \| Related Data Sites A marine boundary delineates an area within which sovereignty, political jurisdiction, or legal authority may be exercised. Sample data in this topic include: Maritime Limits National Marine Sanctuary Boundaries Marine Managed Area Boundaries (top)

	Hurricanes Search for Data \| View Topic \| Related Data Sites NOS provides helpful hazard-related information and tools to state and local coastal programs to assist assessment, response, and mitigation. Sample data in this topic include: Post-storm Hurricane Photography Historical Hurricane Tracks (top)

	Environmental Monitoring Search for Data \| View Topic \| Related Data Sites Monitoring and observation programs range in scope from collecting water level and current measurements to measuring contaminant levels in fish, mollusks and estuarine bottom sediment. Sample data in this topic include: National Status & Trends Mussel Watch Benthic Surveillance Bioeffects Assessment Water Levels Currents Environmental Sensitivity Index Maps National Estuarine Research Reserve System-wide Monitoring Program (SWMP) (top)
