The term G.S.V.D. means Geodetic Survey Vertical Datum of 1929. Before 1929, all maps were prepared with elevations based on “mean Sea Level Datum of 1929.” In the 1970’s, the name was changed to the National Geodetic Vertical Datum (NGVD) of 1929. One of the reasons for the name change was that it was found that the sea is actually not level.Jul 26, 2013.

I am Bill Crawford. I was born and raised in Ft. Lauderdale, Fla., bisected by the Intracoastal. I graduated from the University of Virginia with a bachelor’s degree in commerce, with distinction, concentrating in finance. I obtained my juris doctor degree from Stetson University College of Law. I have practiced law for more than 43 years. I am a professional historian and author of the award-winning book, “Florida’s Big Dig,” (2008) the story of the Atlantic Intracoastal Waterway.
I have practiced law in Florida since 1975. Along the way, I developed a keen interest in researching and writing history, publishing numerous scholarly journal articles and one award-winning book, “Florida’s Big Dig,” the story of Florida’s Atlantic Intracoastal Waterway, using my legal pbackground to understand legal transactions, deeds, wmortgages, bonds, preferred stock, and legal descriptions of land and water.
In recent years, I have maintained a limited practice consulting with other professionals on various historical land and water issues, including sovereign, riparian, and submerged land rights, focusing on the Atlantic Intracoastal Waterway and Florida inland waterways.
I maintain a broad regular website here at www.floridasbigdig.me and a website solely on how the book was researched as well as some of the major themes explored. The website on the book itself is at www.floridasbigdig.com.
The website on contacts for professional services is at www.floridasbigdiglawyer.com?. A fifteen-page outline of my book
