We are conducting basic research
on efficient delivery of GIS services over a thinwire.
Just as in serving large images, we believe that the
active visualization servers
provide many advantages for this application.
The issues here is fundamentally different
from that of serving large digital images -- the underlying
data here is geometric and logical. The
issue of multiresolution models for GIS data is a critical one.
Our goal is to build a system that will allow a user to
smoothly pan and zoom around a large geography in real time.
