Abstract: This volume presents the methods used to collect, tabulate, and analyze basic data on surface composition. of six selected Thailand study areas--Nakhon Sawan, Lop Buri, Chiang Mai, Fran Buri, Khon Kaen, and Chanthaburi. Fifteen mapping classes that expressed the different soil mass strength and soil surface strength conditions were established. The criteria used in isolating these classes were (a) that each class be identifiable using air-photo interpretation techniques and (b) that each class exhibit similar variations in strength with moisture content. Areas with equivalent trafficability characteristics in terms of the 15 map classes were delineated on 25 surface composition maps together covering the six study areas. This delineation was accomplished through interpretation of maps and air photos with control data in the form of field and laboratory information. The maps are presented in Volume VIII of this report. A compromise between the desired degree of mapping class refinement and that dictated by the photo-interpretation criteria was necessary because of the nature of the field data. During the mapping program when sample site data were extrapolated to unsampled areas, the degree of mapping refinement was of necessity only fair to low. It is recommended that additional studies be conducted on the use of air-photo identification techniques in classifying soil strength conditions. This approach is believed to be basically sound; however, more field verification of predicted values will help to determine the reliability of this approach.
