Until the advent of this new map viewer, a valuable resource was largely unavailable to coastal planners. Now, US Coastal Survey maps are free for broad use.

This project builds on earlier efforts to provide comprehensive analysis of the 40 T-sheets that cover the southern California Bight (SCB) from Point Conception to the US-Mexico border. High quality scans of the original T-sheets produced between 1851 and 1889 were obtained along with the surveyor notes.
