National Oceanic and Atmospheric Administration
National Geodetic Survey
The National Geodetic Survey site maintains numerous sets of data related to surveying and navigation.

The NOAAServer gives access to distributed NOAA data and information.

NOS Mapfinder
The NOS MapFinder service provides "one stop shopping" for images and data from a number of National Ocean Service (NOS) offices. The cornerstone of NOS MapFinder is a robust set of products available directly from the Web. These products are offered by theme (e.g., coastal aerial photography, low resolution nautical charts, coastal survey maps, etc.) Products are accessed through a spatial inventory that locates and describes all data that NOS possesses for each theme.

Great Lakes Environmental Research Laboratory
GLERL Data Library
The Great Lakes Environmental Research Laboratory's (GLERL) data library with topics including bathymetry, biologic, historic, and real-time data.
