NAD83 and WGS84 are only horizontal datums. Here is some information about the most current vertical datum in the U.S. http://www.ngs.noaa.gov/faq.shtml#GeodeticVSTide On Mon, Feb 8, 2010 at 2:35 PM, Jeffrey Ollie wrote: > On Mon, Feb 8, 2010 at 3:25 PM, Anthony wrote: >> On Mon, Feb 8, 2010 at

Jeff, One more thing. You may want to be careful about eliminating duplicates. For example, if you have a microwave tower that communicates with two other sites, it will be in the FCC data twice at the same location. To me that is not a "duplicate" as each record will contain different informat
