The Hydrographic Survey Meta Database

In 2005, the design and future considerations of this hydrographic survey metadata data base (HSMDB) were presented at the Marine Technology Society Proceedings. This paper will provide an update. The HSMDB now offers a user interface to previously unavailable hydrographic survey data, data products and metadata conveniently and freely over the Internet. The product descriptive report images alone have had over 90,000 hits over the last year. Moreover, over 1,500 archived HSMDB records have become the source of Coastal Services Center (CSC) Geospatial one-stop entries. The most exciting new product is the addition of new bottom sample information. This paper will illustrate how to access and use the new HSMDB user interface. Several examples of queried HSMDB displays called survey rap sheets will be shown. Survey products will also be outlined. Lastly, future considerations of HSMDB use in hydrographic survey accuracy and geospatial overlays will be discussed.
