Want to highlight the contact between two geological units in your drillhole data? Using the geological 3D-GIS query you can create points at specific geological contacts. These are especially useful for the construction of your geological contact surface.
You can also create points at the top, middle, or bottom of an interesting geological unit and restrict your search to a specific interval. For example, create a point at the middle of the first occurrence of your mineralized horizon that is greater than 10m in length.
