From Directions Magazine:

“Machover Associates, a computer
graphics consultancy reports
that the worldwide market for scientific visualization in 2D and 3D
will grow from $10.7 billion in 2005 to $17.2 billion in 2010. The big
money is in 3-D imaging, the majority of which comes from private
industry. Still, a substantial amount of federal research funding is
available as well. Geospatial technologies have a role here: one
visualization film shown at Siggraph last week illustrated the 2002
Elbe River flooding and the use of geodata played in predicating the
need for evacuations.“
