the limitation Lucas mentions existed in older versions of Place Syntax. Newer versions do not have this limitation. It has been gone for a while now.That is: there is no unit limitation in current versions of PST.
This is great news.
If I am not mistaken, the old version had a limit of just 32.000 elements, is this correct? Can I assume that Stockholm has about 32000 plots, or is it larger?
What is the size of the biggest map you ran with the new version until now?
