3D Grid in Map Window
This tutorial shows how to visualize the 3D grid in the map window.
Requirements
- A new project
- Terrain model grid file (.grd)
Step 1. Add 3D layer to the map
1. See Add (multiple) 3D grid
2. “Add new layer” 
in the map window and pick the “GeoScene3D object based” layer type –> “(3D grid)” –> next and finish.
Step 2. Visualize the 3D grid
1. Open “map properties and layer manager” 
in the map window –> right click the “AEM 3D grid” –> “layer properties” 
2. In the slice menu the “elevation slice” can be edited to the desired index elevation.
- See next picture for difference in index elevation.
Step 3. 3D grid depth regulation
- The visualization of the 3D grid can be limited to a specific depth below a surface e.g. terrain.
1. Layer properties –> slice –> elevation –> click “grid slice (e.g. terrain)”.
- To the right is the standard setting “offset in depth” 0 that correlates to data visualization at terrain or surface level.
- To the left is the standard setting “depth step interval” set to 1 that correlates to a 1 meter jump up/down in the griddata from 0 meter.
- Example: If you enhance the step interval e.g. to 2, you are now jumping up or down in the grid depending on your up/down choice in “offset in depth”. Furthernore if “Auto. Update” is clicked, you will see the immediate response to your up/down clicks.
- See next picture for difference in “offset in depth”.
Step 4. Results
- The offset depth of this picture is 16 meter compared to the previous picture with offset depth at 12 meter. This depth is attained by clicking two times on the “offset in depth” with the interval setting at 2 meters.
