This book was released on 1968 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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, Pran 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. (Author).

This book was released on 1968 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of exact terrain conditions and vehicle characteristics is a prerequisite for predicting vehicle performance across terrain. The development at the U.S. Army Engineer Waterways Experiment Station of an analytical model for predicting the cross-country speed of ground-contact military vehicles resulted in the isolation of those terrain factors that significantly affect the locomotion of ground-contact vehicles. Those factors are encompassed in four factor families--surface composition, surface geometry, vegetation, and hydrologic geometry. Since a condition of this study was to establish the effects of terrain on vehicle locomotion in Southeast Asia, six areas in Thailand were selected for detailed study. Data summaries are included as appendixes to the appropriate volumes. Air-photo interpretation techniques used to identify air-photo patterns of terrain features are presented in Volume VI. The method used to synthesize the factor-family maps into factor-complex maps for mobility purposes is presented in Volume VII. Map sets for each of the four factor families for the six study areas are presented in Volume VIII. (Author).

This book was released on 1967 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the methods used to collect, tabulate, and analyze basic data on the surface geometry of selected areas in Thailand. The descriptions of surface geometry features are so designed that the descriptive values can be used directly as input to an analytical model for predicting the cross-country speed of selected military vehicles. A method for classifying, interpreting, and mapping surface geometry factors from aerial photographs (air photos) was developed. Utilizing the field data collected and the air-photo interpretation methods developed, 25 surface geometry factor-family maps were prepared, together covering six selected study areas (Nakhon Sawan, Lop Buri, Chiang Mai, Pran Buri, Khon Kaen, and Chanthaburi). These maps are presented in Volume VIII of this report. Air-photo interpretation methods for predicting and mapping surface geometry factors were largely successful. However, the degree of accuracy achieved for each of these factors varied considerably, being a function of the scale, quality, and vintage of the existing photography. It is recommended that studies be continued to develop air-photo interpretation techniques to improve the reliability of estimation of surface geometry factor values. (Author).

Book excerpt: The mission of Project MERS was to determine the effects of physical environments, with emphasis on those of Southeast Asia, on the performance of cross-country ground contact vehicles. A long-range objective was to provide data which could be used to improve both the design and employment of such machines.

This book was released on 1968 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vegetation characteristics were measured according to established sampling procedures at 295 sites within six areas of Thailand. From these samples, stem diameter and spacing data were extracted for analysis, since these are the factors that significantly affect performance of ground-contact vehicles. A dual classification system was devised for mapping these factors in which spacing values of 0-1.5 m,>1.5-3.0 m,>3.0-9.0 m, and>9.0 m were determined for stem diameters of 5 cm or less, 13 cm or less, 23 cm or less, and 130 cm or less, and stem diameters of 3 cm or more, 8 cm or more, 15 cm or more, and 25 cm or more. Map units were identified and delimited on aerial photographs by established photo-interpretation keys and techniques. Twenty-five 1:50,000-scale map sheets were prepared for the six study areas, on which 72 distinct mapping classes were identified. The vegetation field data for the six study areas are summarized.
