Inkscape Cartography and Drafting Tools

Inkscape is a great program for creating cartographic maps. It would be even better for this task with some simple CAD and cartography tools. Inkscape can be extended through Python extensions. (http://wiki.inkscape.org/wiki/index.php/Extensions)

Task Suggestions

  • Enter circle by Coordinate.
  • Edit node coordinates in dialog box.
  • Enter straight line by coordinates.
  • Enter arc by coordinates and angle.
  • Make line parallel to another line.
  • Make text parallel to another line.
  • Make line perpendicular to another line.
  • Add nodes at distance along path.
  • Match label parts to path segments.
