Within Windows you can use WinZip to create a suitable file, but you need to rename the file
to have the .kmzextension.
Revisiting the Realtor’s Toolkit
In Chapter 12 examples of both archaeological- and realty-related tools in Google Maps were
examined. Both followed similar principles, the overlay of information that is known about a
location, either in the past or the potential in the future.
Within Google Earth the same principles can be used to display information, either in an
identical manner or in a far more interesting alternative.
Using an Overlay
A simple overlay was used in Chapter 12 to suggest a potential office plan and layout. The dis-
play was simplistic, partially because of limitations in Google Maps, but also because with just
a flat image to play with, there is very little that could be done to alter the view and representa-
tion of the office plan. With Google Earth you can follow the same principles to add an image
overlay to the map.
Figure 17-10 shows the overlay in an almost identical situation to the one used in Chapter 12.
