Mapping

1. get and uncompress the tbase.Z file from http://dss.ucar.edu/datasets/ds759.2/into the m_map
directory.
2. Run m_tba2b('PATHNAME') to store the resulting 18Mb binary file as PATHNAME/tbase.int.
3. Delete the original ASCII file tbase.
4. Edit the PATHNAME setting in m_tbase to point to the location of this file.
That's it! Test things out with this map of the western mediterranean:
m_proj('lambert','lon',[-10 20],'lat',[33 48]);
m_tbase('contourf');
m_grid('linestyle','none','tickdir','out','linewidth',3);
2. As of Apr 2006, there is a corrected higher-resolution (2 minute) database ETOPO2. Download
http://dss.ucar.edu/datasets/ds759.3/data/etopo2_2006apr/etopo2_2006apr.raw.gz (a gzipped binary),
gunzip it into a 116Mb file, edit the PATHNAME setting in m_etopo2 to point to the location of this file,
and
