GEE Enterprises Classic Plane Table with Accessories Survey Set - Product Features
- Plane Table with Aluminum Tripod Stand Standard
- A plane table is a device used in surveying and related disciplines to provide a solid and level surface on which to make field drawings, charts and maps.
- In use, a plane table is set over a point and brought to precise horizontal level. A drawing sheet is attached to the surface and an alidade is used to sight objects of interest. The alidade, in modern examples of the instrument a rule with a sight, can then be used to construct a line on the drawing that is in the direction of the object of interest.
- By using the alidade as a surveying level, information on the topography of the site can be directly recorded on the drawing as elevations. Distances to the objects can be measured directly
