FOREST ROAD PLANNING

PLANNING FOREST ROAD NETWORKS REQUIRES EXAMINATION OF LARGE AREAS FOR FINDING AND EVALUATING ALL POSSIBLE ROUTES. INACCESSIBILITY AND THE LACK OF DETAILED TOPOGRAPHIC MAPS MAKE AIRPHOTO INTERPRETATION OFTEN THE ONLY PRACTICAL METHOD OF INVESTIGATION. A SYSTEMATIC APPROACH IS TAKEN TO THE INTERPRETATION OF PRINCIPAL FACTORS, NAMELY TOPOGRAPHY, SOIL TYPE AND DRAINAGE REGIME, WHICH IN THEIR COMBINED EFFECT DETERMINE THE LOCATION AND COST OF A ROAD. AIRPHOTO INTERPRETATION PERMITS ONE TO SCAN LARGE AREAS IN A SHORT TIME, AND TO IDENTIFY CRITICAL LOCALITIES EARLY IN THE INVESTIGATION, ALLOWING ONE TO CONCENTRATE FIELD CHECKS TO THESE AREAS. ONCE THE OPTIMAL ROAD NETWORK HAS BEEN DETERMINED AND MARKED ON AIRPHOTOS, DETAILED FIELD LOCATIONS CAN BE COMPLETED AS REQUIRED BY CONSTRUCTION NEEDS AND WITHOUT EXTENSIVE RECONNAISSANCE. ROAD NETWORK PLANNING ON THE BASIS OF AIRPHOTO INTERPRETATION ALLOWS THE OPTIMUM APPLICATION OF THIS PRINCIPLE. /AUTHOR/
