        Special Issue on Networking Support for Remote Conferencing


Real-time  interactions  with  colleagues  through  network   communications
are rapidly  becoming  an  important  means  of  communications  as  network
technologies become  better  able to  support  such applications.     Recent
experiments with remote conferencing such as the multicast of  presentations
from the  March,  1992  meeting  of  the  IETF  across  the Internet,   have
demonstrated the viability of the technology and have pointed out new  areas
of investigation.   Remote conferencing puts  special demands on  networking
hardware and protocols:   data must  be generated,  delivered and  presented
at the  destination in  a timely  fashion.   Remote  conferencing  protocols
may prefer  to discard  out of  order or  late data  rather than  delay  the
presentation at the destination.   Multi-way  conferences may use  multicast
algorithms to minimize  the volume of  transmitted data.   Data  compression
techniques may be used to  reduce the volume of data.   The purpose of  this
special issue is  to focus  on issues and  experiences with  internetworking
support for remote conferencing, such as:



  o Multicast protocols for remote conferencing

  o Multi-media data transmission protocols

  o Data compression algorithms for video and audio data

  o Service requirements for remote conferencing data delivery

  o Experiences with remote conferencing systems


Papers submitted for this  special issue of  Internetworking:  Research  and
Experience should meet  the journal's normal  requirements for  publication.
Original papers,  not published  elsewhere or  not simultaneously  submitted
for publication elsewhere,  will be considered.   The  manuscript should  be
double-spaced, with a separate title  page including the author(s)  name(s),
affiliation(s) and  address(es).    The body  of  the manuscript  should  be
preceded by a  summary of no  more than  200 words.   Up to  five key  words
should be provided for indexing.   Four copies  of the manuscript should  be
delivered by January 15, 1993 to:

The SDH meetings were designed to be small meetings at which a high
level of interpersonal communication could be maintained. Lots of time
to be available for carefully selected papers AND discussion. This is
not the mode found in any of the other meetings mentioned by Mike Gould.
All are large (thousands) and dedicated to making money for the
organizations involved. GIS/LIS serves a real role in the applications
area (and new comers do like to see the exhibits) but it is a completly
different type of meeting. AutoCarto started out alone and even tried
to go international for a while. Now (despite the best efforts of
individuals such as David Mark and Nick Chrisman) it has decayed (IMHO)
to a series of sessions drowned in the mass of surveyors, etc.

An annual series of international technical meetings, with the focus
perhaps shifting on alternate years, would be interesting. In my mind
the model for these should be the SDH meetings and not large,
commercial operations.

Actually, Peter, what they are talking about is SunView, the windowing system
that Sun used to support (that ran at kernel priority, took less resources,
generally performed much better, etc etc... sigh).

In SunView, you had two independent windows, just like X.  However, the
graphics screen was "slaved" somehow to the text panel, and characters typed
while the mouse pointer was in the graphics screen were redirected (I don't
know by whom) to the text panel.  If you wanted to type in another window,
such as your mail tool, no problem - just move your mouse pointer over there
and type.

3D look & feel and jazzy scroll bars notwithstanding, new toys are not always
an improvement....

The idea sounds grand but I am a bit leery about the choice of
format for the archive.  My leeriness :-) comes from having never

Line Thinning

A couple of weeks ago, there was some discussion about line
thinning and the use of Fractals for the "improvement" of lines.
Frank Hoffmann accused us that we haven't read Perkal's work,
among other things. I made a comment somewhat out of context.
I would like to expand on this discussion to set things a little
straighter as far as my contribution is concerned.

Perkal:
Perkal's work was discovered and TRANSLATED into English
in 1966 (Michigan Geographical Papers).  It was used in
many areas of geography. It is the basic idea for
line matching and interpolation in Odyssey and might
even be carried over to ARC/INFO.

Line "augmentation":
In 1972/73, David Douglas developed a subroutine which
he called "Wiggle". Wiggle added random curves to lines to make
them look more natural. Some people found that highly unscientific
and critisized the approach with sometimes rather harsh words.
Five hears later, quite a few geographers became all goo-goo-
ga-ga over Fractals and some of the same people whod criticized
David suggested to "augment" lines with Fractals.

I never warmed to either approach because, in my opinion, the eye
finds and remembers specific "landmarks" along lines which, if
distorted, distort the whole line. Babs Buttenfield in her PhD thesis
worked on this idea and suggested that the "character" of a line
is the most important feature and fractal augmentation does not
take that into account.

Fractalizing lines does not make much sense in cartography
in my opinion. For anything else, a simpler algorithm like
Wiggle (maybe a recursive Wiggle) would equally do.

Good stuff.  But I would like to expand the view slightly.  Variables may
be spatial, thematic or temporal.  They may be measured at Nominal,
Ordinal, Interval or Ratio level. They may have varying resolution (cells
for spatial data, categories for thematic data, clock precision or
sampling interval for temporal data, to name just a few).  Rather than
speaking of acceptable or unacceptable forms of analysis, I think it's
important to remember that, depending upon the level of measurement and
type of data, any particular operation may produce reasonable or
unreasonable results.

For instance, suitability levels are, at best, ordinal measures.  If one
adds, subtracts, multiplies or divides the suitability levels of polygons
of different layers that are coincident in space, then one is producing
results that are not very defensible, mathematically.  But this is done
all the time in GIS in the business of siting facilities.  I don't think
that we should build systems that would dissallow such operations.  I do
think that we as a professional community should understand and condemn
the RESULTS of such analyses as derived from unreasonable and faulty
applications of method.

X-To:         GIS-L@ubvm.cc.buffalo.edu

All these things have a life.  The early Auto Carto conferences made a real
contribution, but the GIS community is now drowning in the same old
"workshops,papers & posters" type of conferences and money's gotten tight.
David Douglas' comments about declining attendance at the last Canadian GIS
Conference in Ottawa match reports of reduced attendance at URISA in
Washington as well.

I agree with the suggestion that -- IF the decision is made to resurrect
Auto Carto -- we require a different approach.  Academics, researchers and
technical staff generally go to conferences for different reasons than
program managers and end-users.  They value different types of
presentations and proceedings and -- in the case of academics --  have a
much more pressing reason to submit and present papers.

Sometimes it's easier to make big changes quickly than small changes
gradually.  For example, do we need to keep the same format EVERY YEAR?
Could the organisation, content and presentation of any such research-based
meetings be changed or refined and *still* appeal to people?

I liked Otago's use of GIS-L to widen participation at the SIRC Conference
in New Zealand earlier this year (e.g., circulation of keynote papers via
GIS-L and immediate follow-up on presentations).  U. of Wisconsin has
broadcast at least one of their GIS workshops via satellite link to remote
locations.

How can we drag our own concepts of symposia into the 21st century?

        Those operations are commonly made in many disciplines,
in order to create indexes to be used for many different purposes.
Can GISers  criticize the validity of those indexes?  They could, as
long as they understood the concepts, principles and objectives behind
the creation of such indexes... but I don't think they could criticize
(not to mention condemn ;-)  ) those indexes simply based on concepts
derived from GIS.

>   analyses as derived from unreasonable and faulty applications
> of method.

        It seems to me that when a researcher develops a methodlogy
for obtaining a  particular index (viability, vulnerability,
capacity, suitability, etc, etc) for a given area, he/she may use
the operation of polygon overaly as a tool.  The use of the tool
may be part of the methodology, but never the method itself.
Obviously, there may be different ways, styles and techniques for using
a given tool, therefore:
    First:  I don't believe that we could easily point to
unreasonable and faulty ways of using a tool (I am excluding here, for
example, the obvious innapropiateness of using a hammer for tighting
a bolt --use of the wrong tool--  or hitting a nail with the hammer's
stick --unefficient way of using a tool--).
    Second: In order to point to "unreasonable and faulty applications
of emthod" we should understand the methodology as a whole, something
that would go beyond the aim of most GIS developers.

        It seems to me that a clarification of the differences
between method and tools is urgently needed.

        Cheers.

There are some which do an okay job, but they don't know about some of
the additional types of BiBTeX (e.g. @inproceedings vs.
@incollection).  I've used a Gnuemacs macro package and there is
another that runs at the shell level.

I have been helping with the Computational Geometry Bibliography
