3D Atlas of Ann Arbor: The Google Earth Approach, Part I

Abstract

The virtual reality files in the first edition of the 3D Atlas of Ann Arbor were all made using a strategy involving Geographic Information System (GIS) software coupled with 3D graphic design software. The process was effective but often time-consuming and the files created were quite large. Indeed, in the latter vein, alternative strategies, such as linking one file to another in a hierarchical pattern were employed so that the reader never had too large a file on screen at a single time. Another issue involving the creation of these files was cost of the software. The process involved many thousands of dollars worth of software (and of time of experts using the software). Small cities had faint hope of being able to maintain a state-of-the-art 3D system without substantial donations of time, software, or both.

Google Earth® offers a different approach. The interactive Earth viewer is, by now, probably familiar to most readers of Solstice. The spectacular shiny Earth-ball causes most to exclaim at its beauty on first sight. Further probing of the interactive capability brings additional admiration for its capabilities.
