description: You can find an executable that does all this at http://crunch.tec.army.mil/software/corpscon/corpscon.html I don't know if you can get source code out of them however.

description: We have compiled a set of C routines as shared libraries which can be called from within IDL to do all those conversions. USGS has a package called PROJ.4 which is cartographic projection software which can be downloaded from their website at http://kai.er.usgs.gov/ftp/PROJ.4/proj.html. Send me an email if you'd like more information on our implementation.

Joe Means Howdy, I have some code to transform from Lat/Lon&nbsp; to UTM in meters for NAD27 and NAD83 (actually WGS84).&nbsp; It resides on a different machine so send it to you ASAP. &nbsp; --&nbsp; Ben Tupper Bigelow Laboratory for Ocean Science tupper@seadas.bigelow.org Pemaquid River Company pemaquidriver@tidewater.net &nbsp;
