Mike,
It’s nice – a brief
description of just what the calculations are would be helpful as well. I am
guessing that intersection ‘nodes’ are connected directly to all
other nodes on both axial lines. Is that correct? Also a way to get the numbers
out would be useful – or perhaps I am missing a trick.

Folks
When you open the software on a 19 inch screen set at 1280 x 768 you should get
something like the attached screen shots of regent street. You can start
drawing in the map window straight away - - I also attach a screen shot of
adding in a new map -
Maybe I should have done a manual for this - next release should have manula
and God willing scrolling

No you cant scroll the screen yet - that is what you need to make sure
that the pixel map fits your screen - basically you can load a pixel map which
is not muchbigger than than the one that you have within the package - for
ascreen of around 1280 x 768 but if you are on a smaller screen then there are
problems - for now keep the maps small
in the next release I will sort out scrolling, I hope

This looks great. However when I open the file and get
the initial map screen, I am unable to scroll across to the information on the
RHS (as though my screen was too small). Perhaps I am missing something -
can anyone help.

Here is a Windows-based
program which we have built in CASA to do space syntax. It not only computes
accessibility or integration scores on the traditional axial line map - the
primal problem - but also does the same for the intersections or junctions
between the axial lines – the dual problem.
The program is free and
therefore not supported. It will continue to be free as future versions are
developed. As yet there is no help and no manual but it is pretty easy to it
figure out. I have not tried it on serious large scale problems but it is
likely to work for most. As yet, there are many additional things that could
make it even more user friendly. You can load you own map although the one
provided is for
The size of the map used
is important. You must know your screen size to be able to use it properly, and
my advice would be that for small screens you should not handle maps which are
greater than about 400 x 400 pixels. The program indicates this. In terms of
the number of axial lines and junctions it will handle then this is up to 500.
If you have any difficulty
unpacking this zip file – the program is only about 360K – then you
can go to the web site.
http://www.casa.ucl.ac.uk/ajax/
and download it from
there where future versions will be released. I will email the Mail Base List
when we do new versions.
I cannot promise that it
doesn't have bugs so Caveat Emptor!
I will talk about the
program and the logics behind it at my invited speech at the forthcoming Space
Syntax Symposium in
( http://www.spacesyntax.tudelft.nl/)
and also in
