Spatial Data Structures

[Rich Shepard]

  For those who are interested, I found this site:
	http://www.icg.tu-graz.ac.at/upload/thesis/main.html It's a doctoral
disseration on R-trees for Visualizing and Organizing Large 3D GIS
Databases. Rather fascinating reading, especially for programmers like me
who are self-taught and do it as a sideline to the money-making activities.
