By setting transit at H , pointing in direction of calculated bearing , and laying off distance HD , point D can be accurately set on AB . Since this traverse method involves measurement of angles , it will not lend itself so readily to ...
The position of rod is then located by distance and azimuth ( Art 23 ) . A hand level ( Art 5 ) is often used to determine elevation of additional points , taking elevations of points on transit line as B M's , as follows : First ...
horiz , and if difference in elev between instrument station and rod station is desired the vert distance also must be computed from the inclined sight . By trigonometry , making one slight assumption , it may be shown that in Fig 25a ...
