Topic: Transformation from wgs84 to Nad27
started by: Quinn
Posted by Quinn on July 06 2001,2:07 pmMr. Bowter or any of you other Guru nut cases out there, I am trying to figure out how to formulate a transformation from wgs84 to nad27...does anyone know a simple way to calculate this? I want it for topozone mapping and I don't have enough fingers and toe's. So lets say I was to use N43* 32.468 W077* 45.876 what would this be converted to nad27 and how did you make this transformation? ahhhhhhhh!!

Posted by Quinn on July 12 2001,1:43 pmHi Jag,
Welcome to the forums by the way. yeah I saw the Jeep transformer before, but what I am looking for is the math behind the scenes, I want to know how they came up with the transformed numbers so I can do it myself.
Posted by Quinn on Aug. 17 2001,6:42 pmAs you can see, I got it all figured out with some help from the "Bro". He's not much on looks and I had to teach him everything he knows about computers, but he does come in handy time to time...
ok-ok...the computer bit was a lie!
Posted by dwr50 on Aug. 20 2001,11:16 pmI tried to use the jeeep.com converter and it gave me the wrong results. When I looked at the MapBlast map provided on the jeeep page the X was way off. The way you enter the cache info on Navicache gives the right results on the Topozone map you get at brillig.com. I would list my caches on Geocaching.com if I could input the information the same way as I do here,but since they us a different standard that requires a conversion, I won't.
