Maps & Charts

About this page

The map cabinets on the third floor of the library contain a collection of paper charts and maps for all areas of the world, and beyond. Many of these can be checked out at the ciruclation desk.

One of the most important local collections in this library is on microfilm on the thrid floor- near the map cabinets.  The microfilm reader and printer is with the microfilm cabinets

Coastal Charts

The entire United States coastline, including islands, large lakes and major rivers are in this set. A chart indicates water features such as depth, navigation channels and the location of shoals and other sunken objects that are hazards to navigation. Shorelines and landmarks visible from the water are also included in these charts.

This library receives the complete set from the U.S. government, kept in the map cabinets (third floor near elevators) labeled "Coastal Charts." The charts are organized in numerical order from the Gulf of Mexico, going counterclockwise around the coastline to southern California. "Our" coastal area is the 13200 range. The highest numbers in the set are for Hawaii and the Virgin Islands.

Bathymetry? Hydrography?

The term “bathymetry” originally referred to the ocean’s depth relative to sea level, although it has come to mean “submarine topography,” or the depths and shapes of underwater terrain. Bathymetry is the study of the "beds" or "floors" of water bodies, including the ocean, rivers, streams, and lakeshttp

Hydrography, measures the physical features of a water body.  Hydrography includes not only bathymetry, but also the shape and features of the shoreline; the characteristics of tides, currents, and waves; and the physical and chemical properties of the water itself.
