COMPARISON OF EARTHWORK MEASUREMENTS BY CONVENTIONAL FIELD AND PHOTOGRAMMETRIC METHODS

THE DIFFERENCE IN EARTHWORK QUANTITIES WHEN COMPARING THE CONVENTIONAL FIELD AND THE PHOTOGRAMMETRIC SURVEY OVER THE ENTIRE LENGTH OF A NINE-MILE SECTION OF INTERSTATE HIGHWAY, WAS 1.26% DIFFERENCE. A COMPARISON OF CONVENTIONAL FIELD TO PRECISE SURVEY, USED AS AN ACCURACY STANDARD, YIELDED A PERCENT ERROR OF -0.95. THE COMPARISON OF PRECISE AND PHOTOGRAMMETRIC YIELDS A PERCENT ERROR OF +0.71. THE PHOTOGRAMMETRIC METHOD CAN PRODUCE RELIABLE EARTHWORK MEASUREMENT FOR ANY TYPE OF TERRAIN, WHEN PROPER EQUIPMENT AND PROCEDURES ARE USED. THE COST AND MANPOWER REQUIREMENT IS CONTROLLED BY THE SAME VARIABLES AS THE TIME, CONSEQUENTLY, WHEN THE TIME IS CONTROLLED BY PROPER PROCEDURES AND PROPER LENGTH OF FLIGHTS IS OBTAINED, THE COST AND MANPOWER WILL BE COMPETITIVE. /AUTHOR/
