<span style="margin: 0px; font-family: Calibri, Helvetica, sans-serif; background-color: rgb(255, 255, 255)">Three-dimensional geological modeling is the technological realization of the cognitive knowledge carried by geologists. It facilitates the communication
of complex subsurface geological relationships and enhances the analysis and interpretation of geological data. In the digital era it is quickly becoming the preferred form of geoscience communication, while also providing enhanced accessibility to increasingly
large and intertwined data holdings of governments, regulators, geotechnical firms, utility and exploration companies. The session organizers welcome contributions from the full breadth of the 3D geological modeling community to enhance information communication
and support science-based decision-making, particularly where there are competing interests of resource allocation within the subsurface volume and pore-space. Furthermore the organizers encourage participation from groups contributing to modeling the subsurface
of the urban environment, and infrastructure engineering. Participation is also welcomed from practitioners interested in the development of data standards for exchange and integration of disparate information applied to 3D geology and the linking of 3D subsurface
information to the standards that are in use for above-ground data. Three-dimensional geological models are increasingly used by governments and other community stakeholders to inform land-use planning decisions and are used extensively by industry to guide
exploration and development decision making. Integrated 3D models also represent a key stimulus for sustained economic development in urban areas where planners and infrastructure builders require progressively more detail and timely product delivery and in
resource dependent regions trying to attract new investment. The target audience includes geoscientists from all themes represented at the conference, with a reliance on understanding of the natural geological environment. The session(s) is open to modeling
methodology, standards, and local, regional, and national case studies. </span><span style="margin: 0px; font-size: 14px; background-color: rgb(255, 255, 255)"><br>
