Sorry about that previous incomplete message. Andy Cave wrote: > It sounds like people currently don't write 1m x 1m pixels Well, yes, we do. We write stuff that is even smaller than that. For aerial photography, you can get into the centimeter range if you fly low enough. What we do now is limit the file size to under 2Gig (for compatibility), and produce hundreds or thousands of files. State and local governments, especially Department's of Transportations like to have the entire count or even the entire state photographed every few years. This is an enormous tracking problem, and if the files could be larger, there would be fewer of them, reducing the tracking problem. -- ed grissom ed.grissom@intergraph.com
