M map

M_map is an extension for Matlab that allows to create georeferenced map figures with coastlines with several resolutions from the gshhs database.

Basic Installation

Gshhs Coastlines Installation

Coastlines from the gshhs database are ready to be downloaded and installed and used by m_map. But a few tweaks are required in order for them to work properly with m_map. Here's what was done:

1. Go to http://www.ngdc.noaa.gov/mgg/shorelines/data/gshhs/.
2. Get and uncompress any or all of the files gshhs_c.b.gz, gshhs_l.b.gz, gshhs_i.b.gz and/or gshhs_h.b.gz (search for version 1.2 in the oldversions folder) in the main installation folder of m_map (usually found in the Matlab/toolbox directory).
3. Then you MUST edit the FILNAME settings in m_gshhs_c.m, m_gshhs_l.m, m_gshhs_i.m, m_gshhs_h.m and/or m_gshhs_f.m and remove the private/ directory; just keep the filename. The files will be found because during the m_map installation, the m_map directory was already added to the Matlab PATH environment.

Now all the gshhs multiple resolution coastlines can be used.
