Hello. I am looking for any source code which takes geographic coord- inates such as Latitude/Longitude, and transforms them to another map projection such as Universal Transverse Mercator (UTM) or to the various State Plane Coordinate Systems. Years ago I was given a small program written in BASIC which did that, but I found out it was laden with result errors. FORTRAN, C, Pascal, even Ada would be fine; even across operating systems (MS-DOS, SVR4, Ultrix, etc.) because I have access to them all and more. Not that I'm lazy, but I do have the book from USGS with regards to the various formulae in making such transformations; I just wish I had the time to actually write the code (spoken like a true rusty programmer). I thought it best to ask first, then leap into the briar patch. If anyone can help me find this I would be grateful to at least hear from you. Thanks in advance, and have a great 1993 if you don't read this until then. -- John N Schmidt KD4EAI, Lab Director + 615-898-5561 M-F 1300-2230Z <7-4:30> Middle Tennessee State University ++ 615-898-5538 or 896-2871 FAX 24H 1500 Greenland Drive, PO Box 135 +x+ GGJNS@KNUTH.MTSU.EDU <Internet Address> Murfreesboro, TN 37132-0135 USA +xx+ MTSU Center for Remote Sensing and GIS TCP/IP ADDRESS [44.34.50.soon] +xxx+ PACKET: KD4EAI@KC4RDJ.#MIDTN.TN.USA.NA

Have you asked archie about GMT?? It is a package available from the University of Hawaii (I think) which is supposed to do most of this kind of thing. Send me email if you want the flyer posted some time back.

There's a tool set called GMT (I have no idea what it stands for, but it's not Greenwich Mean Time) that lives at kiawe.soest.hawaii.edu (128.171.151.16) in /pub/gmt that does this and bunches more. spl -- Steve Lamont, SciViGuy -- (619) 534-7968 -- spl@szechuan.ucsd.edu UCSD Microscopy and Imaging Resource/UCSD Med School/La Jolla, CA 92093-0608 "Living alone is living in perpetual irony and thinking, more and more frequently, Why not." - Joyce Carol Oates, "The Boyfriend"

In addition to GTM, you may want to look at the General Coordinate Transformation Package (GCTP) which Gerald Evenden maintains on charon.er.usgs.gov. It is UNIX C code which seems to be quite portable.
