Authoring instructions

Modules

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

TODO:

Existing symbols

New

  • extra/bridge:
  • extra/n_arrow1:
  • extra/n_arrow2:
  • extra/fiducial: (use 45 degree symbol rotation if you wish to align ticks with grid lines)
  • extra/half-box:
  • geology/strike_line,box,triangle,circle:
(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:

Other contributions

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
  • 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

  • A collection of EPS North Arrows from SUNY ESF

Hydrology symbols

-

Geology symbols

National Park Service symbols

Tree symbols

Weather symbols

some ideas here:


  • Write new d.module to draw wind barbs?
