众所周知，城市地区内的植被分布对于提供一系列生态系统服务至关重要。虽然城市规划者和人类地理学家熟悉描述和探索建筑空间体积性质的方法，但很少有研究开发出富有想象力的方法来可视化从树梢到地面的城市植被的复杂空间和体积结构。使用波形激光雷达数据来测量城市绿地的三维性质，我们探索了不同的方式，虚拟地，有形地与描述城市植被的三维分布的体积模型。使用波形激光雷达数据处理成体素（体积像素），并尝试各种创造性的方法来可视化数据的体积性质，我们描述了新方法的开发，用于映射城市绿色体积，使用地理信息系统（GIS），Minecraft，3D打印和计算机数控（CNC）铣削过程的组合。我们展示了如何使用这些方法来揭示和探索城市绿色体积的复杂性。我们还描述了使用这些模型来吸引不同受众的体积数据的结果。我们解释了这些产品如何容易被一系列城市研究人员和利益相关者使用：从城镇和市议会，到建筑师和生态学家。
The distribution of vegetation within urban zones is well understood to be important for delivery of a range of ecosystem services. While urban planners and human geographers are conversant with methodologies for describing and exploring the volumetric nature of built spaces there is less research that has developed imaginative ways of visualising the complex spatial and volumetric structure of urban vegetation from the treetops to the ground. Using waveform LiDAR data to measure the three-dimensional nature of the urban greenspace, we explore different ways of virtually, and tangibly engaging with volumetric models describing the 3D distribution of urban vegetation. Using waveform LiDAR data processed into voxels (volumetric pixels) and experimenting with a variety of creative approaches to visualise the volumetric nature of the data, we describe the development of new methods for mapping the urban green volume, using a combination of Geographic Information Systems (GIS), Minecraft, 3D printing and Computer Numerical Control (CNC) milling processes. We demonstrate how such methodologies can be used to reveal and explore the complex nature of the urban green volume. We also describe the outcome of using these models to engage diverse audiences with the volumetric data. We explain how the products could be used readily by a range of urban researchers and stakeholders: from town and city councils, to architects and ecologists.
