3 D Maps created using OziExplorer 3D (6/7)
This grid / DEM consists of some 100 x 100 values, representing a 5 m grid in nature.
The naked relief of al hill.
The 3 D map software OziExplorer3D uses a DEM (generated using MATLAB or received from another source) to place an ordinary 2 D map on top of the 3 D shape. Thus the 2 D map becomes the texture. To increase the 3 D effect optional lighting is available.
If we use some of the 2 D color maps created above we get results like these.
The absence of contour lines and color helps to place find information on this grey map.
Other colors make the hill appear to “glow”.
If this is applied to one of the 2 D findmaps the result looks like that
Of course, it only makes sense to do this with pictures that show geographical information. Technically speaking, though, the map software accepts all sorts of picture files as textures. This principle gives the user a lot of freedom.
With OziExplorer 3D maps can be turned and zoomed into the most favourable position. .
Best find overview.

Using aerial pictures as textures can make nice effects as well. Lets conclude this article with a 3D aerial photo combined with the positions of the best finds.
The combination of the 2D and 3D maps shown above can be helpful in many aspects of treasure hunting. I would be glad if some readers got inspired by these pictures.
