LARGE DATASETS AND HYDRO GEOLOGICAL MODELING USING GEOSCENE3D

With the large and complex data sets of today, sophisticated tools are required to gain the insights of these datasets. In Denmark, large scale mapping with geophysical tools has been carried out for a number of years. In order to do geological interpretations and modeling of these massive amounts of data, a tool has been developed for visualizing these data and for building hydro geologic models based on the data.

A tool named GeoScene3D has been designed and developed for this purpose. The tool is widely used by the Danish governmental agencies. With this tool, it is possible to visualize surfaces, points, boreholes, 1D and 2D geophysical frequency and time domain measurements, as well as incorporating seismic sections, and other data types to establish a geological model. Powerful visualization and geologic modeling is combined in the same application.

GeoScene3D uses 3D views that can be maneuvered freely around and through data , 3D fences and cross sections, 2D cross section viewers, and 2D map viewers (GIS). An unlimited number of viewers of each type can be active simultaneously. Geological modeling can be carried out in all viewer types and is immediately reflected in all other viewers.

GeoScene3D can link to unlimited amount of data as long as data is in an orthogonal XYZ coordinate system. However, because of limitations in computer performance and memory only data within a user specified extent is visualized at a time. This extent and location of this extent is easily changed by the user and GeoScene3D automatically extracts data from data sources within the new extent. In most cases GeoScene3D links directly to data in their native formats.

The poster will present layered models as well as voxel models of complex geology from mapping areas in Denmark and will present the audience to some of the concepts used to establish these models.
