NOAA's Coast Survey offers several products and services for Geographic Information Systems (GIS) users. Below is a brief description of each and links to our offerings.

The NOAA ENC® Direct to GIS web portal provides comprehensive access to display, query, and download all available NOAA ENC® data in a variety of GIS/CAD formats for non-navigational purposes using Internet mapping service technology. Nautical chart features contained within a NOAA ENC® provide a detailed representation of the U.S. coastal and marine environment. These data include coastal topography, bathymetry, landmarks, geographic placenames and marine boundaries.

Coastal Maps are geo-referenced nautical chart backdrops in TIF/TFW format for GIS. These maps are not for navigation. The Extracted Vector Shoreline product contains topologically clean files of the charted Mean High Water and Mean Lower Low Water shorelines.

A joint demonstration project for Florida's Tampa Bay region. NOAA and USGS merged their bathymetric and topographic data into a digital elevation model (DEM).

A tool used to transform elevation data from one vertical datum into another to combine or compare data

A cooperative Web mapping portal providing spatially-referenced links to real-time meteorological, oceanographic, reiver and water quality information from multiple federal and state agencies and institutions.
