Hi Jiang Bin & Liu Xintao,
 
great job! But, there are some small groups of axial lines isolated from other lines in the London map. Not sure how much this will distort the colour spectrum. This also reminds us that manual checking and correcting is necessary when generating axial map.
 
By the way, it is great that Xintao is willing to help others to create axial maps. I will probably contact him later for his help.
 
cheers,

Hi, to follow up Xintao's post, these lines are automatically generated from street maps. we are writing a paper on it, and hope to present in the space syntax conference.

By the way, xintao is willing to help you to generate the lines if you just tell him which city. This is free service without pay :-)

Thanks and cheers.

Bin

The patterns look interesting

Hi, attached is the updated axial lines, which have a better visual effect. We redrawed the axial lines according to the color level, i.e. we put the red ones on the top, and the blue ones in the bottom. The previous pdf file did this in the opposite way, which generated a bad visual effect.
 
Sorry for inconvenience.

Best regards,
 
Xintao

Subject: Axial lines verification

Dear all,
 
I have generated axial lines of six cities, which are Copenhagen, London, Paris, Manhattan (New York), San Francisco and Toronto, respectively. I have also rendered the shapefiles by using Local Integration in ArcMap (please see attached .pdf file). Now the problem is, how to verify the axial lines? Are these patterns correct? Especially for Manhattan and San Francisco, they show a quite different pattern.
 
Any of your comments and response are highly appreciated. Many thanks in advance.
 
Best wishes,
Xintao
 
P.S. If anyone want to generate axial lines, then I can help. I am volunteered.
