The Use of Geographic Information System (GIS) for Geotechnical Data Processing and Presentation

Geotechnical information acquired from site and laboratory tests are vital for a safe and economical design of building and infrastructure works especially in land development projects. This paper describes the use of GIS in processing and presenting geotechnical data into formats that are useful to engineers, planners and land development professionals. A case study in Seri Iskandar, District of Perak Tengah, Perak, Malaysia is discussed in this paper. In this study, data stored in GIS systems are processed and presented into maps describing soil types and soil strengths (SPT values) at various depths. Thus, the data are always available and this can reduce a lot of time to retrieve them.
