LIDAR maps of Central Puget Sound
LIDAR (LIght Distance And Ranging, also known as Airborne Laser Swath Mapping or ALSM) is a relatively new technology that employs an airborne scanning laser rangefinder to produce accurate topographic surveys of unparalleled detail. LIDAR "sees" through vegetation, providing fascinating insights into geological features.

NOAA Nautical Chart On-Line Viewer
The nautical chart is a fundamental tool of marine navigation. It shows water depths, obstructions, aids to navigation, channels, shoreline, and more – hopefully all the information mariners need to navigate safely. NOAA’s 1,000-plus U.S. coastal and Great Lakes nautical charts are viewable here on-line. Each chart is up-to-date with the most recent Notices to Mariners. Use these on-line charts as a ready reference or planning tool.

Shoreline photos by the Washington Department of Ecology
Between 1992 and 1997, the Washington State Department of Ecology acquired oblique aerial photography of the state's entire 2,500 miles of marine shoreline. The collection of over 10,000 photographs provides a valuable educational monitoring tool for coastal managers and the public. The true-color photos comprise a continuous series, panning left to right along the shoreline. The photos were taken to optimize sun angle, shoreline orientation, and low tides. Oblique photos are useful for interpreting bluff geology and land-sliding, riparian vegetation, and shoreline modifications such as bulkheads and seawalls.
