All the source code, support data, PostScript and HTML versions of all documentation, and UNIX (including HTML) manual pages can be obtained by anonymous ftp from several mirror sites. We also maintain a GMT page on the World Wide Web (http://gmt.soest.hawaii.edu); See this page for installation directions which allow for a simplified, automatic install procedure (for a CD-R solution, see http://www.geoware-online.com.)
The GMT tar archives are available both in gzip
and bzip2 format. If neither of these utilities
are installed on your system, you should know that the former
program is available from GNUD.1 while the
latter can be obtained from RedatD.2.
bzip2 compresses much better than gzip:
for example, the full resolution coastline database is only
29 Mb in bzip2 format compared to a hefty
44 Mb in gzip. These files have the
.bz2 suffix.
The GMT archives are as follows:
All of the above archives are also available as Windows ZIP archives, e.g., GMT_progs.zip. For Windows users who do not want to compile themselves, there are two zip files with Win32 executables:
The netCDF library that makes up the backbone of the grdfile I/O operations can be obtained from Unidata. A compressed tar file can be accessed (in binary mode) from the file netcdf.tar.Z in the anonymous FTP directory of unidata.ucar.edu. The software distribution includes a PostScript file of the netCDF User's Guide, and there is also online documentation from their web site. [netcdfgroup@unidata.ucar.edu is available for discussion of the netCDF interface and announcements about netCDF bugs, fixes, and enhancements. To subscribe, send a request to netcdfgroup-adm@unidata.ucar.edu]. Precompiled libraries for WIN32 are also availableD.3.
