DETERMINATION OF CAPABILITIES OF ELECTRONIC EQUIPMENT FOR USE IN PHOTOGRAMMETRY

TWO ELECTRONIC DEVICES WERE TESTED AND EVALUATED IN ACTUAL PRODUCTIVE WORK AS WELL AS IN SITUATIONS WHERE THEIR FULL CAPABILITIES COULD BE DETERMINED. THE ELECTROTAPE MODEL DM-20 /DISTANCE MEASURING INSTRUMENT/ AND THE AUTO- TROL SCALES, MODEL 3900 /PRODUCES CROSS SECTION INFORMATION FROM AERIAL PHOTOGRAPHY/ WERE EVALUATED. IN GENERAL, BOTH PERFORMED WELL AND IN CERTAIN APPLICATIONS CAN PRODUCE QUALITY WORK AT A REDUCED COST. THE ELECTROTAPE WAS FOUND TO BE FASTER AND MORE ACCURATE THAN NORMAL FIELD METHODS OF MEASURING DISTANCES LONGER THAN 1500 FEET. IT WAS FOUND THAT THE USE OF THE ELECTROTAPE WILL SAVE AS MUCH AS $1,000 OVER CONVENTIONAL METHODS ON A TYPICAL HIGHWAY DESIGN PROJECT. THE AUTO-TROL SCALER WAS FOUND TO PRODUCE VERY GOOD CROSS SECTIONS FOR USE IN DETERMINATION OF EARTHWORK QUANTITIES, IN HYDRAULIC STUDIES OF RIVERS AND STREAMS, IN DETERMINATION OF VOLUMES OF BORROW PITS, ETC. ALSO, IT WAS FOUND THAT THE USE OF THE AUTO-TROL DEVICE WILL SAVE BETWEEN $500 AND $600 PER LINEAR MILE OF CROSS SECTIONS OVER NORMAL FIELD METHODS. /BPR/
