Import raster data as 2D overlays that are draped to the terrain. If you don't have geographic co-ordinates to define the location of a 2D overlay, you can position 2D overlays in-canvas using reference points.
Once you have imported, configured and displayed 2D overlay data in your model, you can fine-tune the placement, scale and rotation of your overlay using reference points.
Once you complete the first set of reference points, the overlay will move to the location you have defined and that set of reference points will be represented by an orange pin. The reference points will be numbered sequentially with different pins. A blue pin represents an incomplete or in-progress set of reference points.
