AERIAL PHOTO INTERPRETATION OF ENGINEERING AND SOIL SURVEYS

THE PAPER SUMMARISES THE USE OF AERIAL PHOTOGRAPHY IN AN ENGINEERING SOIL SURVEY IN NORTH LINCOLNSHIRE. BLACK AND WHITE PHOTOGRAPHY AT DIFFERENT SCALES AND SEASONS WAS STUDIED AND COMPARISONS BETWEEN THE DIFFERENT TYPES WERE MADE. SOIL TYPES WERE IDENTIFIED AND SOIL BOUNDARIES DRAWN ON THE PHOTOGRAPHS. AFTER FIELD CHECKS, ADJUSTMENTS WERE MADE TO THESE BOUNDARIES. SOILS WERE CLASSIFIED ACCORDING TO THE BSCS SYSTEM AND THE DATA ON EACH SOIL STORED ON COMPUTER FILES FOR FUTURE USE. SOIL MAPS WERE PRODUCED FROM SINGLE PHOTOGRAPHS USING AN AUTOMATIC CO-ORDINATE READER AND AN ELECTRONIC COMPUTER TO TRANSFORM THE PHOTO CO-ORDINATES OF THE SOIL BOUNDARIES INTO NATIONAL GRID CO-ORDINATES AND PLOT THEM TO A PRESET SCALE. MAPS PRODUCED IN THIS WAY WERE NOT AS ACCURATE AS THOSE PRODUCED USING PHOTOGRAMMETRIC METHODS BUT THE ACCURACY WAS WELL WITHIN THAT OF THE ORIGINAL INTERPRETATION.(A)
