The soil survey conducted in the Pran Buri study area covered an area of approximately 570 sq km 220 sq mi. Reconnaissance was made along all accessible roads and tracks. Soils were studied at road cuts and at exposures along drainage channels. In areas of good accessibility, borings and profile pits were made in order to study the soil in greater detail. Between 15 and 20 observations per square kilometer were recorded. Detailed field data were mapped on air photos at a scale of 120,000, then transferred from the air photos to series L708 Army Map Service topographic maps at a scale of 150,000.
