A propos du livre

Présentation de l'éditeur

Excerpt from Plane Table

1. The Plane Table is a drawing board in connection with suitable devices for setting, and keeping it level. The alidade is a straight edge, called the rule and a line of sight. The line of sight is sometimes the edge of the rule, sometimes the line of a pair of compass sights set in the line of the edge of the rule, or it may be the line of sight of a telescope so mounted upon the rule that this line of sight revolves in a plane at right angles to the lower face of the rule. When-a telescope is used, the plane of revolution of its line of sight is set parallel to the edge of the rule, or to contain the edge of the rule.

2. In the ordinary use of the Plane Table, a piece of paper is fastened on the board and the lines surveyed, and points that are determined, are platted at once upon the paper. A good quality of drawing paper is commonly used. This paper may be fastened on the board in a variety of ways. If it is to remain there long, and the board is well shrunk, it may be best to shrink it on and stick the edges fast with mucilage. It may also be tacked down with very small curtain tacks. Thumb tacks are used. Clamps are used, and rollers beneath the board are used to some extent. If the paper is larger than the board fasten the edges beneath the board.
