GeoScene3D is a 3D Geological modelling software for visualizing geoscience data, building geological models in order to distribute the results to stakeholders. The software is well suited for geoscientists in public and private organizations working with engineering geology, groundwater, soil contamination or other tasks involving compilation and interpretation or visualization of a variety of data types. GeoScene3D enables visualization of a broad range of geoscience data. For example wells, geophysical data, soil and water chemistry, terrain surfaces and geological layers.Furthermore, it is also possible to build geological models using the software in a well-defined modelling process. From the manual, or semi-automated production of layer interpretation points, through the generation of layer surfaces using advanced interpolation techniques, to the final export of layer surfaces for further processing in other software, like FeeFlow, Modflow or similar. GeoScene3D is the standard platform for geoscience data in Denmark and is continuously developed in collaboration with the Danish Geological Survey (GEUS), the Danish Nature Agency and major Danish engineering companies. The software handles a wide variety of use cases with users facing different tasks in their day to day work. The result is a practical, versatile and robost program with the functionality to handle everyday practical problems the geologists face in many situtations, both in the public and private sector.
