+The result is 2 scripts.

+One is the nmea.php
+
+Designed to use a COM port from Windows (swappable to /dev/ttyS?_) and manage a buffer and NMEA message parsing, nema.php digests verbose NMEA messages down to timestamped, comma delimited data files.
+
+log-analysis.php
+
+this script globs the current directory for all the files that were created by nmea.php.  It replays the files sample by sample, converting Lat/long to relative pixel positions on a GD canvas.  Depth is indicated by color, configurable, but currently sweeping from light green over shallow to dark blue over deep.  It coughs out a number of PNG files, depth, water temperature and sample frequency.
