I improved the coloring of the 3D elevation map to reduce the brightness variation and bring out more details:
Here is the 2D elevation map of the same area:
With the improved color-to-elevation mapping, the steps in the 2D elevation map have been eliminated and its resolution is better when the colors are centered around an elevation of interest. You can now see the mower marks in the NNW field:
And I found a way to generate the 2D elevation map with the texture of the underlying objects showing through without being too heavy handed (as in current DD implementation, IMO):
If you click on the map above to make it full screen, then it has a pseudo-3D quality in some areas due to the color choices, particularly around the tall trees in red.
Next, here is the zoomed in map from above with textures showing through:
Finally, here is my first stab at a conformal, 3D elevation map where the elevation is relative to local ground. It shows the tallest trees are down in the SE corner. Once I import LiDAR data, its accuracy will improve.
All of the maps above would look better if done inside DD, since there is higher resolution data available. My maps are reconstructed from the exported 3D model which carries only a fraction of the detail in the DD 2D maps.
