Spatially enabled would be nice but I suspect that might be asking too much. The concept is a shared environment where scientists can project a reasonably large (say 2m x 1m) raster or vector images onto a (digitise-ready) screen and trace over key elements which are then captured (the tracings ie) as some sort of coordinates/graphic elements. I'm aware of smaller personal systems that do this. Thanks in anticipation. Jon Stirzaker Geoscience Australia Web: www.ga.gov.au -
