Modeling Thickness Variations in Surfer 101
Isopach maps are often used in geology to illustrate thickness variations between two layers, such as the top and bottom of a coal seam or stratigraphic layer. If you have surfaces defining the elevation of the top and bottom of a geologic unit, you can use Surfer to create Isopach or isochore maps.

Join technical support specialist, Drew, for our next free webinar where he will show you how to use Surfer’s powerful new tools to delineate the true vertical thickness and true stratigraphic thickness of a structural unit to generate both types of maps.

Specifically, the presentation covers the following topics:
- The difference between Isopach and Isochore maps
- Using Surfer’s new Isopach tool to create both Isopach and Isochore maps
- Visualize the Isopach maps using contour layers and 3D surfaces
- Use Surfer’s Grid Volume tool to calculate area and volume between surfaces (with varying grid geometry!)
- Extract volume calculations between layers within a specific polygon boundary

Space is limited, so sign up for the session that works best for you today!
