Sketching

The sketcher (or book person) is tasked with recording the survey data, drawing a scaled line-plot with that data, and drawing a scaled, symbolic, and accurate representation of the cave passage that’s being explored. The traditional, and still often used technique, is to record this information on water-resistant paper using a pencil and protractor. Phones or tablets equipped with an active digitizer on the screen can be used to record the same information digitally.
