Geographical Information System of soil data for construction purpose: Retrieving the physical soil characteristics from bore log and Google earth

Field soil investigation prior to the foundation design of any structure is a must for the design engineer. Since the cost of such operation is rather high, then it is sometimes impractical. The design and the preliminary cost estimation of the construction are then impossible to be prepared. This paper applies Geographical Information System - GIS all over Bangkok area thus enable engineer to retrieve the physical characteristics of soil layers from the existing soil data. In addition, utilizing the feature of Google earth can be illustrated more visibility in the required position of boring log and position of retrieved soil boring log data.
