THE USE OF LANDSCAPE CLASSIFCATION IN PLANNING ENGINEERING WORKS

IN PLANNING DEVELOPMENT ON LAND, THERE IS A NEED, AT THE RECONNAISSANCE OR PRE-INVESTMENT STAGE, FOR GENERALIZED INFORMATION ABOUT TERRAIN CONDITIONS TOGETHER WITH SOCIAL FACTORS WHICH MIGHT INFLUENCE THE PROJECT. BEFORE PLANNING CAN BE COMPLETED AND DEVELOPMENT CAN COMMENCE, THERE IS A FURTHER NEED FOR DETAILED INFORMATION, BOTH QUALITATIVE AND QUANTITATIVE, ABOUT POINTS, LINES OR AREAS. EXISTING PROCEDURES FOR THE ACQUISITION OF SUCH INFORMATION AT BOTH LEVELS- EVEN WITH THE USE OF AIRPHOTO INTERPRETATION TECHNIQUES-DO NOT PROVIDE AN ECONOMIC AND RAPID MEANS OF DOING SO, PARTICULARLY IN THE LESS DEVELOPED AREAS OF THE WORLD WHERE BACKGROUND INFORMATION OF A SCIENTIFIC AND TECHNICAL CHARACTER IS EITHER LIMITED IN EXTENT OR NON-EXISTENT AND NEARLY ALWAYS DIFFICULT TO OBTAIN. THE DEVELOPMENT IS DESCRIBED OF A SYSTEM OF COLLECTING, COLLATING AND STORING INFORMATION ABOUT TERRAIN CONDITIONS IN TERMS OF THE TERRAIN TO WHICH IT REFERS. NATURAL SUBDIVISIONS OF LANDSCAPE ARE PROPOSED AS MAPPING UNITS IN THE TYPES OF TERRAIN SO FAR STUDIED; THE BASIC UNITS ARE CONSISTENTLY RECOGNISABLE ON AIR PHOTOGRAPHS AT A SCALE OF 1:30,000, AND, IN SOME INSTANCES OF 1:80,000. IN SOME TYPES OF COMPLEX TERRAIN NOT YET STUDIED AN AIRPHOTO SCALE LARGER THAN 1:30,000 MAY BE REQUIRED TO RECONISE BASIC UNITS. LANDSCAPES ARE CHARACTERISED BY THE RECURRENCE OF PATTERNS, EACH COMPRISED BY A SMALL NUMBER OF SUCH UNITS. THESE RECURRENT PATTERNS PROVIDE AN ECONOMIC METHOD OF SAMPLING AND THE MEANS OF RAPID MAPPING OVER LARGE AREAS BY EXTRAPOLATION. THE SYSTEM, TOGETHER WITH A DATA STORE, IS PARTICULARLY SUITABLE FOR MULTI-PURPOSE OF INTEGRATED SURVEYS BECAUSE THE DATA STORE REVEALS INFORMATION AVAILABLE, AND THUS PROVIDES THE MEANS OF AVOIDING REDUNDANT WORK. /AUTHOR/
