A DISCUSSION IS GIVEN OF TWO SURVEY PROJECTS, ONE USING THE MRA-1 TELLUROMETER, THE OTHER USING THE TELLUROMETER AND MODEL 4B GEODIMETER TO DETERMINE THE ACCURACY IN POSITION OF CONTROL POINTS SET ALONG THE STAKED CENTERLINE OF THE PROPOSED HIGHWAY. THE FIELD COSTS FOR SURVEYING AND STAKING THE DESIGNED ALIGNMENT ON THE GROUND WERE DETERMINED FOR THE TWO METHODS. THE FIRST METHOD WAS APPROXIMATELY ONE-THIRD THE COST PER MILE FOR THE SECOND METHOD. NO ATTEMPT WAS MADE TO COMPARE THE COST OF OFFICE COMPUTATIONS FOR THE TWO METHODS. EVALUATIONS OF BOTH METHODS YIELD THE FOLLOWING CONCLUSIONS' 1/ A FIELD-SURVEYED AND STAKED CENTERLINE CAN BE CORRELATED WITH THE DESIGNED AND PLANE COORDINATE COMPUTED POSITION OF THE CENTERLINE ON THE MAPS BY USING PRECISE FIELD SURVEYING METHODS FOR MEASURING THE PLANE COORDINATE POSITION OF ACTUAL CENTERLINE POINTS WHEN THE STAKING IS DONE ON THE GROUND, 2/ A TOPOGRAPHIC MAP COMPILED BEFORE THE DESIGNED CENTERLINE WAS ESTABLISHED ON THE GROUND CAN BE USED FOR MEASURING CROSS-SECTIONS, 3/ A DATUM SHIFT CAN BE ACCURATELY DETERMINED USING MODERN ELECTRONIC DISTANCE-MEASURING EQUIPMENT, AND 4/ ADVANCE TARGETING ON THE GROUND OF STATIONING POINTS ON THE CENTERLINE STAKED FOR THE PROPOSED HIGHWAY /BASE LINE/ YIELDS MORE RELIABLE RESULTS AT LOWER COST THAN IS GENERALLY REALIZED WHERE REMOTE CONTROL IS ESTABLISHED AFTER PHOTOGRAPHY IS ACQUIRED.
