GMT is a freely available software package developed by Paul Wessel and Walter Smith. The GMT commands produce Postscript output which is converted to GIF in order to display on the Web. The database is implemented through David Hughes' mSQL database server. All CGI programming is coded in PERL, although Ghostscript is called to do the Postscript to GIF conversion.
Future Plans Provide more information on different map projections.
Expand the feature data sets. Allow user extraction of data in the specified region from available datasets. Use 'cookies' to preserve the user defined region and map parameters.
