usamap
Construct map axes for United States of America
Syntax
Description
usamap 'conus'
and
usamap('conus')
create an empty map axes for the
conterminous 48 states (that is, all states excluding Alaska and Hawaii).
usamap
with no arguments presents a menu from which you
can select a single state, the District of Columbia, the conterminous 48 states,
or all states.
returns
the handle of the map axes.h
= usamap(___)
constructs three
empty map axes, inset within a single figure, for the conterminous states,
Alaska, and Hawaii, with a spherical Earth model and other projection parameters
suggested by the U.S. Geological Survey. The maps in the three axes are shown at
approximately the same scale. The handles for the three map axes are returned in
h
= usamap('all')h
.
usamap('allequal')
is the same as
usamap('all')
, but usage of 'allequal'
will be removed in a future release.

Tips
All axes created with
usamap
are initialized with a spherical Earth model having a radius of 6,371,000 meters.In some cases,
usamap
usestightmap
to adjust the axis limits tight around the map. If you change the projection, or just want more white space around the map frame, usetightmap

resizes the axes containing Alaska and Hawaii to the same scale as the conterminous states.
