  • Simplify raster.
  • Classify raster.
  • Fill null cells.
  • Create polygons from classified raster cells.
  • Create ridges and valleys from elevation raster.
  • Classify slopes from elevation raster.
  • Classify aspect from elevation raster.
  • Create elevation raster from LIDAR data.
  • Create elevation variability raster.
  • Create raster from polygon coverage.
• Implement basic IO support for common vector and raster formats.

  • Paint grid as PNG image file.
  • Paint grid as SVG.

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.
