----------------------------Original message---------------------------- MAPS-L Lisa Recupero did indeed do a Master's paper on comparisons of GEODEX etc. She spent some time here at UT and worked through GEODEX. I have a copy of her paper and I think it was is well done. She will hopefully present her findings and information about the various systems she evaluated at the NACIS meeting this Fall in Silver Spring, MD. (Right Lisa?). Lisa is on the NET.
