Plane Table

For drawing accurate maps in the field.  Note:  do not overtighten on tripod -- will become impossible to remove.

Use with an alidade for sighting to features and drawing rays.  Alidades range from the simple style shown in the photo, or a telescopic alidade, or even an improvised alidade such as a three-sided engineer's scale.  Oriented with a compass -- Brunton recommended for accuracy and inclusion of a bubble level.
