Up to now geotechnical information has been offered by various organizations but often with differing data content and presentation methods, lack of detail in the data and other inconveniences for users. Amid dramatic improvements in the capabilities of information related equipment a unification of the contents and items that geotechnical information should contain is required. At the same time, in design and similar applications an improvement in reliability is required and there is a desire for statistical processing of geotechnical information that includes formation and sedimentation eras. In order for such requirements to be met many aspects concerning the data necessary for geotechnical information need to be urgently considered, as the unification of such data is ongoing. Additionally it is desirable to utilize geotechnical information, rather than only for geological surveys and design, and to combine it organically with geographic information. This paper catalogs the problems posed by these requirements.
