Volusia county calibration readings on artificial reefs
These readings on a variety of Florida east coast artificial reefs that can be used for calibration readings in that area. This material generously supplied by: John Lane, Volusia County Reef Research Dive Team, www.volusiareefs.org.

LORAN TDs and WAAS or DGPS GPS L/L readings were taken on separate LORAN and GPS units when anchored over a ship, barge or large pile of material on each site.

DIGAWO DATA BASE

This is an old government data base of wrecks and obstructions in the North East US. It contains stuff that may no longer be there and also has some readings that are too rounded off to be of any use. All the data is in Lat/Lon. The original name was something like: DIGital Archive of Wrecks and Obstructions

Florida Artificial Reefs

A listing of hundreds of artificial reef sites arranged by coastal county (34 files). DISCLAIMER: The GPS and LORAN entries in the chain field indicates which format the original coordinates were obtained (if known). The other set of coordinates was calculated and is probably not as accurate as the original set as only the government ASF tables were used. Where both was indicated, I do not recommend that they be used as calibration readings as I have seen problems with them. These were derived from: http://www.floridaconservation.org/marine/ar/ARind.htm

Florida wrecks

A listing of wrecks for diving from a site called Deeper Stuff. They say: "The numbers below represent what I currently have from various sources and are highly accurate. They were taken at the actual site by reliable equipment, not calculated from LORAN or obtained from unreliable sources. Some were given to me, and others I have collected myself, like the PeeWee Vreeland; published Broward County numbers for this shipwreck have proven inaccurate. I am NOT promoting them as dive sites, nor should they be dove by anyone without the proper training, equipment, and experience to do so" - Mark Zurl"

The loran numbers were calculated by the LoranGPS program using government ASF tables.

Team Live Wire GPS Coordinates

http://www.teamlivewire.com/

They say: "The GPS numbers listed on this site have been collected using several sources through the years.  Though many of the numbers have been verified, all have not.  USE THESE NUMBERS AT YOUR OWN RISK,  If numbers used from this site are found to be incorrect, please contact us so changes can be made.  These numbers are updated regularly to ensure best possible accuracy and to add new numbers."

The sites readings were manipulated into the LoranGPS format and loran numbers calculated from them without calibration using the governmant ASF tables. Some of the readings may have originally been converted from Loran with unknown accuracy.
