⚠️Martinpovolny: added link to git repository with some more simple symbols

== Authoring instructions ==

* [[GRASS_Programming_Howto#Display_Symbols]]

== Modules ==

''Note that starting with GRASS 6.3 many modules can rotate a symbol by a given angle.''

* {{cmd|ps.map}} ''point'' command
* {{cmd|ps.map}} ''vpoints'' command
* {{cmd|d.graph}} (Icon support was added for GRASS 6.1)
* {{cmd|d.vect|version=65}} ''rot_column'' option in GRASS 6.5 and newer

== Existing symbols ==
* Browse built in symbol files in the [http://trac.osgeo.org/grass/browser/grass/trunk/lib/symbol/symbol/ SVN Web interface]

[[image:Symbols.png]]

=== ''New'' ===

* <tt>extra/n_arrow1</tt>: [[image:Symb-n_arrow1.png]]
* <tt>extra/n_arrow2</tt>: [[image:Symb-n_arrow2.png|30px]]
* <tt>extra/fiducial</tt>: [[image:Fiducial_125.png]] (use 45 degree symbol rotation if you wish to align ticks with grid lines)
* <tt>extra/ping</tt>: [[image:Symb-ping.png|23px]]
* <tt>extra/half-box</tt>: [[image:Half-box.png|23px]]
* <tt>extra/bridge</tt>: [[image:Symb-bridge.png]]
* <tt>[[Symb-fish|extra/fish]]</tt>: [[Image:Symb-fish.png|42px]]
* <tt>geology/strike_line,box,triangle,circle</tt>: [[Image:Symb-geo.png|300px]]
* <tt>extra/ring</tt>: <span style="color:#000090"><font size="+2">Ο</font></span>

: (ps.map can take rotation angle from an attribute column for each site with the '''''vpoints''' rotatecolumn'' instruction; to make open symbols set the fill color to 'none'; to make a double sided dip symbol draw the same symbol twice with 180 rotation between the two commands)



== Combinations ==

You can overlay and rotate symbols to create combinations or color codes. For example:
: [[Image:Circross-overlay.png|40px]][[Image:Half-overlay.png|120px]]

=== More simple symbols ===

Available for any use by anyone.

=== Symbol families ===

Add-on symbol packages for download

* Convert SVG to EPS format (for use with ps.map) with the following command:
: (requires [http://www.inkscape.org Inkscape])
inkscape -z -T -E outputfile.eps inputfile.svg

* We still need someone to write a little script to convert EPS images into GRASS's display symbol format. It would be nice if the same converter could create d.graph drawing commands as well.

==== North Arrows ====

* http://www.gfoss.it/download/ (Free Italian Symbol set in SVG from [http://www.gfoss.it/drupal/simboli GFOSS.it])

* A collection of EPS [http://www.esf.edu/la/resources/GOL/north/2D_vector/default.htm North Arrows] from [http://www.esf.edu/la/resources/GOL/GOL_main.htm SUNY ESF]

==== Hydrology symbols ====
-

==== Geology symbols ====

* http://www.gfoss.it/download/ (Free Italian Symbol set in SVG from [http://www.gfoss.it/drupal/simboli GFOSS.it])

==== National Park Service symbols ====

* Set of National Park Service symbols in EPS format from [http://www.trailgraphics.com/2009/03/trail-graphics-symbols-parksymbol-as-epspng/ trailgraphics.com]

==== Tree symbols ====

==== Weather symbols ====
''See also the [[Meteorology]] wiki page.''

* http://www.gfoss.it/download/ (Free Italian Symbol set in SVG from [http://www.gfoss.it/drupal/simboli GFOSS.it])

some ideas here:
* http://www.meteor.wisc.edu/~hopkins/aos100/sfc-anl.htm
* http://www.weather.org.uk/resource/wwsymbol.htm
* <nowiki>http://weatheroffice.ec.gc.ca/data/analysis/jac00_100.gif</nowiki>
* http://ows.public.sembach.af.mil/index.cfm?section=SFCAnal

* ''In progress'': Write a new d.barb module to draw wind barbs.
: Choice of arrows, ping symbol, stick, or classic wind barb
: Choice of starting points from sparse vector map points (like d.vect) or regularly sampled from a raster grid (e.g. {{cmd|d.rast.arrow}} or Euler's method vector plot).

==== Miscellaneous symbols ====

* SVG from [https://trac.osgeo.org/qgis/browser/trunk/qgis/images/svg QGIS's Subversion code repository] (see above for instructions on how to convert to .eps)
* TODO: convert to/from [http://gmt.soest.hawaii.edu/gmt/doc/gmt/html/GMT_Docs/node139.html GMT symbol format] (look in /usr/share/gmt/custom/*.def)
