My database stores records in one of three formats. NAD27, NAD83 and WGS84. According to the following post (http://groups.google.com/ group/Google-Maps-API/browse_thread/thread/41d45dc53f208f39/ c87810319e7d590b?q=nad27&rnum=2), NAD83 and WGS84 are essentially interchangeable, however NAD27 is not.
NADCON http://www.ngs.noaa.gov/TOOLS/Nadcon/Nadcon.html has an executable and an http page that will perform conversions, however it doesn't seem to have a web service, nor does it inform the reader of the algorithm for the conversion. Roughly .02% of my data is in NAD27 format, but it's pretty important to my client to map these data if at all possible. So, my question is: 1) does google maps api offer a converter somewhere within the geocode function (or heck, anywhere else really) 2) is anybody aware of a web service, javascript, java, .net or coldfusion object that i can use to do this conversion? 3)does anybody know the actual alogorithm used by NADCON to convert NAD27 to NAD83? (the questions are mutually exclusive) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
