Authoring instructions

Modules

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

  • ps.map point command
  • ps.map vpoints command
  • d.graph (Icon support was added for GRASS 6.1)
  • d.vect rot_column option in GRASS 6.4.1 and newer

Existing symbols

New

  • extra/n_arrow1: and extra/n_arrow1b:
  • extra/n_arrow2:
  • extra/n_arrow3:
  • extra/n_arrow4: (shown with a "N" text element placed above it)
  • extra/n_arrow5:
  • extra/n_arrow6:
  • extra/n_arrow7a: and extra/n_arrow7b:
  • extra/n_arrow8a: and extra/n_arrow8b:
  • extra/n_arrow9:
  • extra/fiducial: (use 45 degree symbol rotation if you wish to align ticks with grid lines)
  • extra/simple_zia:
  • extra/ping:
  • extra/half-box:
  • extra/bridge:
  • extra/fish:
  • geology/strike_line,box,triangle,circle:
  • geology/strike_half-bowtie:
  • geology/strike_cleavage, strike_parallel and circle_cross:
second symbol above is strike_cleavage rotated four times
(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, or four times with 0,90,180,270 degree rotation)
  • geology/half-arrow_left,right: (two left-side half-arrows shown, one of which has been rotated 180 degrees)
  • extra/ring: Ο
  • extra/dim_arrow:


Combinations

You can overlay and rotate symbols to create combinations or color codes. For example:

Symbol families

Add-on symbol packages for download


  • Convert SVG to EPS format (for use with ps.map) with the following command:
(requires Inkscape)
inkscape -z -T -E outputfile.eps inputfile.svg
  • If Inkscape chokes on a large SVG file: try opening it in Firefox, then go into Print Setup and turn off page number and URL decorations, and Print → To File. This will save a PostScript file, which can be converted to .eps with the ps2eps program (at least on Linux and Macs). As of Feb 2011, this method works much better than using recent versions of Scribus, Karbon, or Adobe Illustrator (all of which did a terrible job).
  • 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. This would go nicely as a Google Summer of Code project.


North Arrows

Hydrology symbols

-

Geology symbols

National Park Service symbols

Tree symbols

Weather symbols

See also the Meteorology wiki page.

some ideas here:

  • In progress: The 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. d.rast.arrow or Euler's method vector plot).
