- We are doing pretty much just what you are. Instead of airplane track, we are
- showing wind vectors and colored objects which represent monitored pollutants.
-
- We are running AVS on a Kubota Pacific Titan. Data is pre-processed on a
- Macintosh Quadra and standard AVS modules do all the visualization. We
- had to "cook" the terrain map, as it is not rectangular in the region of
- the earth we're dealing with.
-
- Should you decide to go this route, I can provide you with some hints and
- tricks.
