As commercial companies such as Dynamic Graphics, Inc. (developer of the 3D geologic sturcture and propertymodeling system, EarthVisionTM), universities, the various geological surveys, and other research organizations have extended traditional mapping techniques toward creation of true 3D geologic structure and property models, access to the information in those models for external uses has not been as good as it ultimately needs to be. One of the primary benefits of a 3D geologic structure modeling system is the enforced consistency of the component zones, fault blocks, and surfaces that comprise the model. Such a model is easily viewed on a computer, picked apart, sliced, rotated and so on . . ., but creating maps, sections, and other electronic outputs from such a model is very important if that model is to be more than a nice curiosity to anyone other than those who can view it on a computer. In this talk, I will review the process of creating such maps, sections and outputs, and discuss why such maps represent an improvement over maps developed independent of an underlying model.

For further discussion on 3D models and their relationship to mapping outputs, please refer to http://www.dgi.com/ and/or contact Skip Pack (email: skip@dgi.com).
