提出了一种测量城市系统密度的新方法。通过将高度详细的高度测量与地形数据等相结合，我们能够量化城市体积。这种新方法在两个单独的案例研究中得到了证明，这两个案例分别与城市环境的时间和空间维度相关。第一项研究研究了阿姆斯特丹市在过去一个世纪的发展。城市容量指标用于可视化和量化城市扩展和集约化过程。为了批判性地分析阿姆斯特丹的时空发展，应用了自组织地图方法。特别注意突出近期多核发展的任何迹象。第二个案例研究比较了荷兰四个主要城市的建筑高度频率和高密度区域的空间分布。此外，还使用赫克曼选择模型同时解释了建成区的存在和实际的城市体积值。
A new methodology is presented that measures density in urban systems. By combining highly detailed height measurements with, amongst others, topographical data we are able to quantify urban volume. This new approach is demonstrated in two separate case studies that relate to the temporal and spatial dimension of the urban environment, respectively. In the first study the growth of the city of Amsterdam over the past century is studied. The urban-volume indicator is used to visualise and quantify the urban extension and intensification process. To critically analyse the spatiotemporal development of Amsterdam the self-organising-map approach is applied. Special attention is given to highlighting any signs of recent polynuclear development. The second case study compares the building-height frequency and spatial distribution of high-density zones in the four major Dutch cities. Additionally, the presence of built-up areas and the actual urban-volume values are explained simultaneously using a Heckman selection model.
