Existing hydrographic data analysis and visualization tools are very powerful, but lack easy access to web data management tools. Virtual globe software provides a gateway to a host of important data products in formats usable by specialized tools such as CARIS, Fledermaus, and Arc/Info. With virtual globe interfaces, users see complimentary and consistent geographic representations of available data in an easy-tonavigate format. We present a preview of visualizations that build upon virtual globe software. These examples are viewed in Google Earth, but could also be implemented in a number of alternative programs (e.g. NASA World Wind, Dapple, OSSIM Planet). We …

Proposed Ais Binary Message Format Using Xml For Providing Hydrographic-Related Information, Schwehr Kurt, Lee Alexander
Center for Coastal and Ocean Mapping
UNH is working with the USCG and NOAA to use XML (Extensible Markup Language) to define binary messages for maritime-based AIS (Automatic Identification System). A draft specification format is under development that will enable hydrographic and maritime safety agencies to encode AIS message contents by providing a bit-level description in XML (informally known the "AIS Binary Message Decoder Ring"). An AIS binary message definition in XML specifies the order, length, and type of fields following a subset of that used by the ITU-R.M.1371-1. The specification is independent of programming language (e.g., can be implemented in C, C++, C#, Java, Python, …
