surveying - 2024 Chicago Open

Question

Instruments for this task undergo a two-peg test to check for collimation error. The Leica Nova TS60 instrument for this task automatically tracks moving prisms. A change point in this task is a location at which both foresight and backsight readings are taken. So-called “dumpy” instruments for this task can be modified with a tilting screw to allow for an additional direction of movement. People performing this task read off of “E-pattern” staffs with red and black markings. (-5[1])The total stations used for this task combine an EDM and a (15[1])(*) theodolite. (10[3])This task (10[2])measures the (-5[1])reduced (10[1])level of various points, where the reduced level is a vertical offset relative (10[1])to (10[1])a reference datum, such as the mean sea level. For 10 points, name this task that makes angular and distance (10[1])measurements (10[1])to precisely (10[1])determine the position of points on the Earth’s surface. ■END■ (0[4])
