This is s.sample, version 0.6B <02 Jan 1995> Copyright (C) 1994, 1995. James Darrell McCauley The man page should have installed automagically. Please check. Don't forget to run your MAKELINKS script. A tutorial is available in s.sample-tutorial.ps.gz, a compressed PostScript file. A LaTeX version is in s.sample-tutorial.tex. No other formats are available. The subdirectory validation/ contains some sample data and output. This is Beta software - so please be sure to keep in touch with me if you have problems. I've only been able to do limited testing. Regarding lat-long data, I'm not sure if this will work correctly. The way it was written, we're doing interpolation over data in a plane (see figure 1 in the tutorial). If this changes from a plane to a curved surface, I'm not sure what happens. --Darrell James Darrell McCauley (darrell@mccauley-usa.com) http://mccauley-usa.com/
