Space Syntax measures
The axial map is used in space syntax analysis to represent and analyse all open public space as a continuous spatial network in order to measure how well connected each street space is to its surroundings. This is done by taking an accurate plan of a built up area and drawing the set of fewest and longest lines that cover all the open space ensuring that lines intersect where adjacent spaces are contiguous. Space syntax analysis computes all the lines in the network according to their relative depth from each other. Depth increases with the number of changes of direction between lines, see Hillier, B. (2007). Each segment map is coloured using a continuous colour scale from blue to red to represent low to high values of the measure.

Choice 
Segment analysis takes each axial line and breaks it into segments at the intersections between axial lines. Segment analysis is concerned with the angular properties of graphs by calculating the relative straightness (least angular deviation or 'angular depth') of each segment from all other segments in the system. Choice is calculated by counting the number of times each segment falls on the shortest path between all pairs of segments within a selected distanceradius where 'shortest path' refers to the path of least angular deviation or straightest route through the system.

Segments 
The maps are sections extracted from the segment map of the Greater London area bounded by the M25. 
Angular Integration radiusn 
Segment analysis is concerned with the angular properties of graphs. This involves calculating the relative straightness (least angular deviation or 'angular depth') of each segment from all other segments in the system. Using this angular metric, lines that are be relatively deep from each other are said to be 'segregated', lines that are be relatively shallow are said to be 'integrated'. See Hillier. and Iida, (2005)

This is a combined measure that created using Global Choice and Global Angular integration.
