Sub-Log Wreck Maps
Shipwreck Database:
This system was started with data from the NOAA Automated Wreck and Obstruction Information System database which has about 12,000 entries in US coastal waters. I've purchased data on another 1200 submarine wrecks and am also adding a few more historic, significant wrecks. I welcome coordinates of wrecks that you think should be listed and may add a system for easy entry of wreck information but for now if you wish you can email them.

Technical Notes:
This application uses the Google Maps API which provides a great amount of map data and a good programming API.
The Sub-Log Shipwreck Map stores all wreck positions and information in a mySql database and serves this information out as XML through a PHP script. The Google Map API uses AJAX technology which is an acronym for Asychronous Javascript and XML. What this basically means is that the map page never refreshes when you do a search or zoom or pan the map. Data and map images are sent in the background to the page and updated without the usual "refresh".
