Document Summary

This document provides only guidelines for midterm exam review, and does not necessarily represent exact midterm exam questions. 1 define terms surveying, observation, measurement, plumb line, elevation and leveling; 2 restate the two fundamental purposes for surveying; 4 describe horizontal and vertical directions, measuring distances and angles; 5 contrast plane surveying and geodetic surveying; and. 1 know units used for angles, distances, areas and volumes; 3 know significant numbers and rules for round-off numbers; 5 define blunders (gross errors or mistakes), systematic errors, accidental (random) errors, accuracy, precision, most probable value, percentage errors (50%, 90%, 95%), residuals, standard deviation, error of closure, relative accuracy (precision); 10 apply error propagation law to estimate the error of computed quantities; and. 1 define datum, mean sea level, level line/surface, vertical direction, elevation difference, leveling, backsight, foresight, height of instrument, benchmark, turning point, intermediate sight, and rod shot; 2 explain principles of differential leveling and trigonometric leveling;
