This Google Earth example of a topo map is an interesting combination. The representation of a third dimension by the isolines together with the raised relief of GE create a layering effect that allows one to fly over and around the mountain while calculating elevations.
This example of a planimetric map appears very basic. It represents the varying patterns of caves in a location in Brazil, samples of planimetric cave patterns. Arrows indicate the direction of water flow (figure 7). What appear to be just simple lines and curves are really the angles and curves of underground canyons.
The LIDAR map of the flooding of New Orleans after Katrina is dramatic representation of the devastating effects of the hurricane and its aftermath. This laser (light detection and ranging) can measure the distance as well depth of the water in the flooded areas of NO. 
A mental map is how one might envision something, in this case their own neighborhood. It is how the individual perceives the geographical area and their cartographic representation of it.
