I just happened to stumble upon an update of a tool to Create Geologic Cross Sections, eXacto Section v. 2.0, that I mentioned in July. Jennifer Carrell at the Illinois Geological Survey wrote this tool. The latest update is from December 8, 2010 and can be downloaded at ESRI’s ArcGIS Resource Center. Our office has used previous versions and finds in very useful in creating cross-sections. I have not tried this latest update.
The Create Geologic Cross Sections–eXacto Section v. 2.0, ArcMap 9.3 written by Jennifer Carrell of the Illinois State Geological Survey is a handy tool for creating cross sections. It requires ArcGIS and a 3D Analyst Extension license. You can create profiles against multiple DEMs at once, define the vertical exaggeration, and have it include contact points. It is well documented and comes with sample data to use with the tutorial.
