the segment analysis is in many ways a refinement of the axial
line analysis (which is the one in space is the machine), and
more importantly, these are both models, not measures.
Integration on the other hand is a measure, and you can run both
local and global integration on both segment maps and axial maps
- it is important to not confuse model and measure. Which
_measure_ in segment analysis is proposed in the guide?
Which is better also depends on what it is you are analysing
(i.e. what is your question?). For movement and many other
phenomena it is today often found that in an urban settlement
segment analysis of the measure angular choice with radii that
need to be tested has the strongest correlation (although there
are some standards you can follow), for other things it might be
integration (local or global), control, or other measures.
However, axial line analysis of integration does give you a
correlation to movement that is quite high in many cases; it is
just that segment analysis tend to have higher. When it comes to
local or global integration on axial line analysis, the radius
that works best shift with morphology and question, but in a
system with a predominantly local movement pattern (such as
traditional european cities) local integration has usually been
the best for correlation to movement flows.
I am not as versed in segment analysis in practice so I'll not
get into details there but rather leave it to someone who is to fill.
Note: If I remember correctly R3 in space is the machine equals
radius 2 in Depthmap, as depthmap does not include the original
line (spatial entity) in the depth whereas that was done in
I am doing a practice about the integration analysis in a small
urban context (for learning), the software also is "Depthmap". I
found 2 type of analysis. 1: according to professor Hillier's
suggestion in "Using DepthMap for urban analysis: a simple guide
on what to do once you have an analysable map in the system",
that is segment analysis, 2:according to the "space is the
machine".that is local(R=3) and global integration analysis.
Now the question is : what is difference between the two? and For
integration analysis, which of them is better?
thank you in advance for your help,
