Google Sketchup Cave Maps
Google SketchUp may be the best free way to display information about caves that is available. From showing the cave location on Google Earth to displaying a complete 3D model with photos, profiles, sketches, notes and anything else you wish to display. With the turning off and on of layers you can select items you wish to display or study. The model can be rotated in any direction in real time and the landscape can be placed right over the cave.
Drawing
Editing and free hand drawings can be created. Google SketchUp has many of the common drawing features of other drawing programs that are expensive.
