Could you please help me.  I am trying to gather addresses of companies/
academic institutions who are involved with Wide Area Distribution of
Geographic Information.  This would involve the capture of aerial photographs,
digitizing the image, and transferring the resultant material from location to
location, based on requirements.  Thus, workstations would exist at key
sites around the Area, displaying the information to users who access it for
particular applications (line maps with data superimposed showing drainage/
telephone cables/elecdtrical ducts), maybe even the location of medical
facilities on a town/city map, which would be of interest to planners etc.
The obvious problem to the communications engineer, is how to best provide a
communications infrastructure to service such a facility at many locations.
The problem is compounded by the time scales and class of data being
transferred.  A user requesting a raster image of a node of a particular line
map will want to see the hotel/hospital/golf course that has been highlighted
by the mouse, so the amount of information required to satisfy the query is
suddenly increased many fold.  The time scale is such that one does not want
the user to have to wait minutes while this image is transferred from a server
located somewhere.

What I would like is any clues as to who is involved in this area, that
includes companies/universities/real=life commercial/research institutions etc.

I can assure you that any information will only be used for research purposes.

I would require the e.mail addresses or postal addresses of the places
concerned.  Please direct your replies to my e.mail address.
Thanks for your time
