Abstract: Geographic Information System (GIS) has been extensively used in geosciences for data management, and distribution of geologic data and maps. GIS can provide functionalities such as overlay of DEM and satellite image, linking 3D features to attribute tables, spatial analysis etc. to create more meaningful geological maps. However, GIS is seldom used to represent the Earth’s subsurface in three spatial dimensions as 3D subsurface geological modeling is a complex task to be applied with the current GIS technology. This paper focuses on the application of GIS technology in the 3D geological modeling. It introduces the GIS linear referencing and dynamic segmenting concept and process in organizing borehole data to aid the creation of 3D geological models. The paper also presents a case study where the linear referencing and dynamic segmenting tools from ArcGIS are used to create the 3D geological models based on the borehole data in Singapore.
