Mapping

Getting started with the M_map MATLAB Toolbox
To get the same map without using the defaults, you
would use
m_proj('oblique mercator','longitudes',[-132 -
125],'latitudes',[56 40],'direction','vertical','aspect',.5);
m_coast;
m_grid;
Notice that longitudes and latitudes are specified using
a signed notation East longitudes are positive. West
longitudes are negative. North latitudes are
positive. South latitudes are negative.
Note that a decimal degree notation is used, so that a
longitude of 120 30'W is specified as -120.5.
The second line draws a coastline, using the 1/4 degree
database. Coastlines with greater resolution can be
drawn, using your own database.
