Hello everyone - This is not really a Therion question. It is more of a general survey question. Therion is sort of involved in the situation, though ... When you are drawing the sketch in the cave, is it normal to ALWAYS make north the same direction on each sheet of paper? What is considered "best practice" in this regard? Background: I have been helping with survey of a cave that has grown to slightly over 5000 feet as of a week ago. I have been both sketching and doing cartography. Therion is my weapon of choice! :-) At least 6 people have done some part of the sketching in this cave. All of us have oriented our sketches so as to best fit each section of cave onto the paper. We always indicate north, but it can be any edge of the paper. The man who is coordinating the project is also doing cartography using Windows tools (Walls, Xara, etc.) He sent me an email today asking if I will commit to making all future sketches with north being the top of the page. He asks because some of the computer work he does results in portions of the sketch being upside-down and therefore more difficult to read. Thanks - Bill Gee
