It is available at: ftp://survey1.tec.army.mil/pub/software/ It handles State Plane Coordinates (for the U.S.), UTM, and lat/lon; all of these with both NAD 27 and NAD 83. You can convert one point at a time or process an ASCII batch file. Version 4 also handles vertical data, a feature I have not used. -- -------------------------------------------------------------------- Andrew McIntire phone (508)457-2352 USGS, Woods Hole, MA 02543 fax (508)457-2310 [log in to unmask] http://coast-enviro.er.usgs.gov/agmc/ --------------------------------------------------------------------
