“Spatio-temporal representation: the challenge of representing (visually 
or computationally) complex geographic phenomena and processes in GI 
science”

Mark Harrower 
University of Wisconsin

*Please note the need to download material IN ADVANCE of the seminar - 
instructions below*

MEETING PLACE

Please note this location carefully.

If you haven’t got the Marratech™ client on your machine, use Java 
webstart to enter WUN Server 2:

http://us.emeetingportal.com/launch.jsp?
sid=363&mep_login&mep_username=WUN&mep_password=WUN

Open the JNLP file. This can take a minute or so.

If you have the client on your machine, enter the same room, WUN Server 2 
from:

http://us.emeetingportal.com/connect.jsp?
sid=363&mep_login&mep_username=WUN&mep_password=WUN

Open the .sdx file.

ESSENTIAL PREPARATION

Given that nature of Professor Harrower’s materials, we simply can’t serve 
all his images from our server on any reasonable timescale. Instead he 
will use the Marratech ™ system’s capabilities for video and audio to give 
this talk in the usual way, but ALL THE ILLUSTRATIVE MATERIALS, including 
an html file with the usual Powerpoint-style text, will be in a separate 
location that you are asked to access as he talks. You simply won’t be 
able to follow unless you do the following well in advance of the talk:

1)	Download from  
http://www.wun.ac.uk/ggisa/seminars/documents/WUN_HarrowerA.zip

and unzip. This is an 80Mb file even when ‘zipped’, so it will take a 
while and may give problems if you have some file size restriction in 
force. If lots of people try to do this on the day close to the time of 
the seminar I doubt that the server the other end will be up to it, so do 
it NOW. There is an alternative version, with not as good quality, in a 
18Mb file at  http://papaya.ilrt.bris.ac.uk/~cmyjs/WUN_Harrower.zip

2)	Ensure that this runs in the browser you will be using on the day. 
(Open index.html)

You’ll need to check on two things. First, depending on the version you 
use you’ll need the ability to run one or others of Flash, AVI, Mpeg and 
Quicktime content (with up to date codecs). Second, some systems will try 
to block at least some of the files. Check that you can unblock and view 
the content. I’d strongly recommend working through the entire 
presentation well in advance of the talk itself. University firewalls may 
well give some problems here!

3)	Folk who use a ‘Datashow’ type projector in a shared facility will 
need someone to access the files at appropriate times in the talk 
and ‘unblock’ the content as necessary.

4)	At the time for the event, when you have joined the session in 
Maratech, please launch a separate browser, open the index.html from your 
unzipped location locally and then re-size your browser to the size of the 
Marratech whiteboard (leaving the video, participant and chat windows 
showing on the right hand side.

I’ve already had a long look at Professor Harrower’s materials and can 
assure you that, as my grandchildren would say, there is some ‘cool’ stuff 
here that you’ll enjoy but that will also give us a lot of food for 
thought.
