Hello,

I am forwarding this to the list on behalf of Overton Mapping
concerning interactive GIS systems that pre-dates August 1995.
He was aware of development of the Tiger Map Server (Plewe,Stuber)
in 1995 and Xerox Parc Map Server (Putz) 1993, which we are responding
to.  Specifically they are interested to learn about early systems that
conform to a client-server model.  If anyone has information about other 
early systems that meet this criteria, please forward relevant information 
to Overview Mapping <info at overmap.co.uk>
