Video: urban network analysis

This video is an impressive ad for the Urban Network Analysis toolkit, which I have never worked with by the way. Network analysis in urban environments is quite popular since it is relatively straightforward to identify the obvious nodes and links. A simple transport network can consist of streets as links connecting nodes at the crossing of these links. Urban Network Analysis seems to add buildings and a large variety of attributes (like jobs, residents, …). It uses this to create network maps of cities that can integrated with ArcGIS10 and analysed using network analysis measures. The measures illustrated in the video are quite simple and common, and by no means exclusive to urban network analysis. But they do become quite powerful when looking at large networks, like entire cities for example. The approach taken here has much in common with Space Syntax, although without the theoretical/interpretative baggage. The video is a pretty good introduction to how to see networks in an urban environment, so do have a look.
