Axwoman3.0: An Analytical Tool for Urban Morphological AnalysisAxwoman is an analytical tool based on space syntax for urban morphological analysis. It is implemented as an ArcView extension. Three functions are implemented using Avenue scripts with different interface modules: drawing with view, computation with view and table, and analysis with table and chart. All these Avenue scripts are packed as an extension named Axwoman3.0 (Axwoman30.avx). A set of icons is created and linked to respective Avenue scripts.Three kinds of methods are implemented with the new version of extension, namely polygon-, line- and point-based approaches. The following figure illustrates the three approaches. The approaches start with spatial partition, i.e. identification of each individual geometric shape to represent small-scale space that can be perceived from a single vantage point of view. According to how the geometric shapes are interconnected or visible each other, a connectivity graph can be derived for computation of various morphological measures. Illustration on area-based (a), line-based (b) and point-based (c) space syntaxA series of analyses can be done with the extension module. Users can use ArcView drawing tools to perform space partition as illustrated in the above figure. Doit tool calculates various measures from the Axial, Point or Housing map including connectivity, control value, integration, local integration, depth etc. Computed results are stored in a table corresponding to the respective map theme. Users can explore data from different perspectives, or import observed data, e.g., pedestrian or other traffic flow rates for a cross analysis.Furthermore, local areas can be selected for analysis. For this purpose, a range of selection tools is implemented with different polygon shapes. Worth noting is the softwares exploration capability. In order to conduct the analysis discussed here, a range of analytical components are provided such as axial, housing and point maps, tables, charts, and so forth. All these components are dynamically linked to each other, so any action applied to one of the components will be propagated to any other.A Quick Start Tutorial名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 1 页,共 7 页 - - - - - - - - - Before starting this tutorial, it is assumed that you have already been through the ArcView Quick Start and understand basic ArcView terminology and interface concepts. It is also expected that you are familiar with the analysis capabilities of the standard ArcView product and are wondering what Axwoman can do for you.In this quick tutorial you will work through three step-by-step exercises, beginning with loading Axwoman3, drawing up axial maps and ending with calculating measures with space syntax. Along the way, side notes give you more information about the concepts and techniques that youre using in the exercises. Youll learn more about these topics in the Axwoman on-line help. This tutorial will guide you through your first few Axwoman3 sessions. You probably have some basic tasks in mind with space syntax, such as drawing up an axial map, point map and housing map and calculating measures, analysing data etc. This tutorial will show you how to perform these tasks and put Axwoman3 to work right away.In this tutorial youll perform these exercises with Axwoman3.0:Exercise 1: draw an axial map, calculate measures with space syntax, and analyse and view correlationExercise 2: draw a housing map, calculate measures with space syntax, and analyse and view correlationExercise 3: draw a point map, calculate measures with space syntax, and analyse and view correlationExercise 1: You can use this tutorial with or without your computer. If you want to perform the exercise on your computer, you should already have installed Axwoman3 and the tutorial data. Its time to begin your first Axwoman3 session!In this exercise youll draw up an axial map.In this exercise youll learn:How to start ArcView,How to load Axwoman3 extension products,How to draw axial maps.名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 2 页,共 7 页 - - - - - - - - - Start ArcViewIn the desktop panel, look for the icon titled ArcView and double-click it.When the ArcView opening banner disappears, youll see the ArcView application window.Load the Axwoman3 Extension1.From the File menu choose Extensions.2.Click in the check box labelled Axwoman3, and then press the OK button on the Extensions dialogue to load the extension.Open a New View1.
