2README file for GMT supplemental mgd77 programs.

6AUTHORS:	Paul Wessel and Michael Chandler
7DATE:		01-MAY-2011
8VERSION:	2 (GMT 5 revision)
9INSTALL INFO:	The mgd77 directory should install under GMT/src
10
11	These programs are intended for use with the marine geophysical
12data files known as MGD77 files.  These data files are NOT supplied with
13GMT; they are the MGD-77 standard exchange format files provided by the
14National Geophysical Data Center*.  The programs greatly extends the
15functionality of the mgg supplement but uses the actual MGD77 data files.
16We also introduce a new format for such data using the netCDF library.
17Unlike the original MGD77 files, the netCDF-based versions (called
18mgd77+ files) can hold additional columns supplied by the user.
19The following is a list of the programs and a short description of what
20they do:
21
22	mgd77convert	A utility to create .mgd77+ files from MGD77 files
23	mgd77list	A data extractor for .mgd77[+] files
24	mgd77info	An information extractor for .mgd77[+] files
25	mgd77path	Gets the full pathnames for .mgd77[+] files
26	mgd77magref	A utility to evaluate geomagnetic reference fields
27	mgd77manage	A utility to manage extra columns in .mgd77+ files
28	mgd77sniffer	A utility for quality control of MGD77 files
29	mgd77track	A track plotter for .mgd77[+] files
30
31man-files for all the above programs can be found in the manl subdirectory.
32An overview of the package can be found in:
33
34Wessel, P., and M. T. Chandler (2007), The mgd77 supplement to the Generic
35   Mapping Tools, Computers & Geosciences, 33(1), 62-75.
36
37Note that the functionality provided by the mgg supplement's gmt2bin,
38binlegs and getlegs have now been generalized to any track data by the
39tools in the x2sys package.
40
41The support file mgd77_paths.txt is put in the
42GMT/share/mgd77 subdirectory directory.

44To install these programs, simply type
45
46	make install
