Dear Girmay,

 the currently best explanation for segment angular integration I believe is found in
Hillier, Yang & Turner. 2012. Normalising least angle choice in Depthmap - and how it opens up new perspectives on the global and local analysis of city space. Journal of Space Syntax 3:2.
In a short summary,
Integration measures network properties in a way similar to (but not the same as) mathematical closeness centrality; i.e. it is based on the inverse of the average distance to all other nodes (within a radius), but there are differences in the precise mathematics. (The differences being larger afaik on the original integration measure than the one developed for segment angular analysis).
Angular means that it is the angular deviation from one segment to the next that is the basic distance measure.
[segment length wgt] means that it also weighs the length of segments into the 'closeness' (effectively the distance).
Like most measures in space syntax, integration measures network properties that are then tested against other phenomena (often but far from always movement flows), so it measures for 'spatial closeness centrality within a network [of streets]', where 'streets' would be replaced if you investigate other ranges of spaces.
I hope this helps and was not all too baisc, I am unsure whether you are asking for more precise mathematics or the overall idea of the measures.

Best wishes

亲爱的吉梅：

       我认为目前对线段角度整合度最好的解释是希利尔、杨和特纳于2012年在深度地图中对最小角度选择进行归一化——以及它如何为城市空间的全球和局部分析开辟新的视角。空间语法杂志3:2。

       简而言之,，

       整合度测量网络属性的方式类似于（但不同于）数学贴近度中心度。即它基于到所有其他节点（半径内）的平均距离的倒数，但在精确数学上存在差异。（原始整合度测量值的差异大于为线段角度分析开发的测量值）。

       角度值是指从一段到下一段的角度偏差，这是基本距离度量。

       [segment length wgt]意味着它还将线段长度加权为“紧密度”（实际上是距离）。

       与空间句法中的大多数度量值一样，整合度网络属性，然后根据其他现象（通常但不总是运动流）进行测试，因此它度量“网络（街道）中的空间紧密度中心性”，如果您调查其他范围的空间，“街道”将被替换。

       我希望这会有所帮助，而且也不是太基础。我不确定你是在要求更精确的数学还是测量的总体思路。

Dear all

In depth map angular analysis, we find different results including 

Choice, Choice [segment length wgt], Integration, Integration[segment length wgt], Total depth and so on.

Can any one explain to me what Integration [Segment length wgt] mean? what is it measuring for? How is it computed? Or can any one give me a reference discussed about this?

Thank you

Girmay K. Berhie

各位

      在Depthmap的角度分析中，我们发现了不同的结果，包括

      Choice, Choice [segment length wgt], Integration, Integration[segment length wgt], Total depth这些值。

      有人能给我解释一下Integration [Segment length wgt] ]是什么意思吗？它测量的是什么？它是如何计算的？或者有人能给我一个关于这个的参考吗？

非常感谢。
