The concept of a geotechnical information system (gtis) that integrates the geotechnical data base of a particular area into a geographical information system is discussed in this paper. The geotechnical data base is obtained from earlier soil investigations and is continuously updated by adding the results of new investigations. The gtis can be used to estimate soil properties at a specified locationwithin a geographical area that may have not yet been explored. A "synthetic" soil boring log and profile can be generated for a particular site within the geographical area using the existing information in the data base of neighboring boring logs in addition to other subjective information about the area such as its deposition history.The feasibility of this concept is demonstrated by a prototype gtisdeveloped along these lines for part of jefferson parish county in new orleans.
