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.

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).

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 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).

This book was released on 1969 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mission of the Degradation Effects Program (DEP), formerly Joint Environmental Effects Program (JEEP), is to extrapolate estimates of lethality and munition effectiveness in DEP test environments to Southeast Asian environments. If these extrapolations are to be reliable it is imperative that the environmental conditions of the test areas be similar to those of Southeast Asia. Accordingly, objective comparisons must be made of DEP test environments and Southeast Asian environments. This report describes and compares some significant vegetation structural characteristics of two selected DEP sites in the Pina and Balboa forests in the Panama Canal Zone (CZ) and four selected sites in two forests and two rubber plantations in Thailand.
