>Is there a method to represent an area of water that is temporary?
For water flow points and lines there are subtypes like permanent (default), conjectural, intermittent, paleo; (these don't all apply to each entity - see the therion book) There are summer, winter subtypes for air draught points. I don't think this was quite what you are asking, however. I would tend to draw the passage dry and label it "floods regularly" or draw it wet and label it "often dry" Bruce -------------- next part -------------- An HTML attachment was scrubbed...
