Placita 7 1/2 " Quad, Pitkin County, Colorado3D Geology Map Using ESRI ArcGIS10

2D Geologic Map

The Placitas Quadrangle covers the southern portion of the Carbondale, Colorado coal mining area near Redstone, Pitkin County, Colorado. In 2010, I presented an example of data capture and conversion into ESRI geodatabase using new 2D and 3D capabilities of ArcGIS10. As an example of a complete 3D geologic map, the draped 2D data from the original maps has been extruded into a fully functional 3D geologic model. This poster will be both a paper printed product and a live digital demo of the data.Willy Lynch, ESRI Energy Team [email protected]
