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 via Google earth to all over Bangkok area thus enables 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. Moreover, it can be applied to everywhere around the world.
