----------------------------Original message---------------------------- A faculty member here at our Energy, Environment, and Resources Center (EERC) is looking for a measurement in miles for the average distance between mean lowtide for the U.S. East Coast and the edge of the Continental Shelf. I advised them that that was a lot to generalize, but they seem to be intent on getting a number somehow. If anyone has information of that sort, or knows of a good source for it, please respond to me directly and I will pass the information on to the EERC. Thanks in advance, Eric -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Eric Schmidt | University of Tennessee | "GIS Ain't Cartography" Cartographic Information Center | [log in to unmask] | -To Be On My Tombstone- *Note New Address* | =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
