<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><b>pscoast</b>
plots grayshaded, colored, or textured land-masses [or
water-masses] on maps and [optionally] draws coastlines,
rivers, and political boundaries. Alternatively, it can (1)
issue clip paths that will contain all land or all water
areas, or (2) dump the data to an ASCII table. The data
files come in 5 different resolutions: (<b>f</b>)ull,
(<b>h</b>)igh, (<b>i</b>)ntermediate, (<b>l</b>)ow, and
(<b>c</b>)rude. The full resolution files amount to more
than 55 Mb of data and provide great detail; for maps of
larger geographical extent it is more economical to use one
of the other resolutions. If the user selects to paint the
land-areas and does not specify fill of water-areas then the
latter will be transparent (i.e., earlier graphics drawn in
those areas will not be overwritten). Likewise, if the
water-areas are painted and no land fill is set then the
land-areas will be transparent. A map projection must be
supplied. The <i>PostScript</i> code is written to standard
output.</p>

the <b><A HREF="gmtdefaults.html#MEASURE_UNIT">MEASURE_UNIT</A></b> setting in .gmtdefaults4, but this
can be overridden on the command line by appending <b>c</b>,
<b>i</b>, or <b>m</b> to the scale/width value. When central
meridian is optional, default is center of longitude range
on <b>−R</b> option. Default standard parallel is the
equator. For map height, max dimension, or min dimension,

<a name="GSHHS INFORMATION"></a>
<h2>GSHHS INFORMATION</h2>
<p style="margin-left:11%; margin-top: 1em">The coastline
database is GSHHS which is compiled from two sources: World
Vector Shorelines (WVS) and CIA World Data Bank II (WDBII).
In particular, all level-1 polygons (ocean-land boundary)
are derived from the more accurate WVS while all higher
level polygons (level 2-4, representing land/lake,
lake/island-in-lake, and
island-in-lake/lake-in-island-in-lake boundaries) are taken
from WDBII. Much processing has taken place to convert WVS
and WDBII data into usable form for <b><A HREF="GMT.html">GMT</A></b>: assembling
closed polygons from line segments, checking for duplicates,
and correcting for crossings between polygons. The area of
each polygon has been determined so that the user may choose
not to draw features smaller than a minimum area (see
<b>−A</b>); one may also limit the highest
hierarchical level of polygons to be included (4 is the
maximum). The 4 lower-resolution databases were derived from
the full resolution database using the Douglas-Peucker
line-simplification algorithm. The classification of rivers
and borders follow that of the WDBII. See the <b><A HREF="GMT.html">GMT</A></b>
Cookbook and Technical Reference Appendix K for further
details.</p>
<a name="BUGS"></a>
<h2>BUGS</h2>
<p style="margin-left:11%; margin-top: 1em">The options to
fill (<b>−C −G −S</b>) may not always work
if the Azimuthal equidistant projection is chosen
(<b>−Je</b>|<b>E</b>). If the antipole of the
projection is in the oceans it will most likely work. If
not, try to avoid using projection center coordinates that
are even multiples of the coastline bin size (1, 2, 5, 10,
and 20 degrees for <b>f, h, i, l, c</b>, respectively). This
projection is not supported for clipping. <br>
The political borders are for the most part 1970ies-style
and do not reflect the recent border rearrangements in
Europe. We intend to update these as high-resolution data
become available to us. <br>
Some users of <b>pscoast</b> will not be satisfied with what
they find for the Antarctic shoreline. In Antarctica, the
boundary between ice and ocean varies seasonally and
inter-annually. There are some areas of permanent sea ice.
In addition to these time-varying ice-ocean boundaries,
there are also ice grounding lines where ice goes from
floating on the sea to sitting on land, and lines delimiting
areas of rock outcrop. For consistency’s sake, we have
used the World Vector Shoreline throughout the world in
pscoast, as described in the <b><A HREF="GMT.html">GMT</A></b> Cookbook Appendix K.
Users who need specific boundaries in Antarctica should get
the Antarctic Digital Database, prepared by the British
Antarctic Survey, Scott Polar Research Institute, World
Conservation Monitoring Centre, under the auspices of the
Scientific Committee on Antarctic Research. This data base
contains various kinds of limiting lines for Antarctica and
is available on CD-ROM. It is published by the Scientific
Committee on Antarctic Research, Scott Polar Research
Institute, Lensfield Road, Cambridge CB2 1ER, United
Kingdom.</p>
