Mapcube, a high performance spatial
visualization system of traffic data, was developed by spatial
databases and data mining group at University of Minnesota. The
Mapcube can be illustrated by the
dimension lattice using a Minneapolis-St. Paul traffic data.
The concept of data cube is the engine behind the MapCube. Traffic
data for highways in Twin Cities area are available from Jan,
1997 to Jun, 1997 for demonstration purpose.
