Built Environment Inventory - City of Greater Geelong

The Built Environment Inventory data show the accessibility of lifestyle amenities and potential health pitfalls.\r\n\r\nThey are the result of a research project initiated by Healthy Together Geelong. The data was calculated using a sophisticated, proprietary method by Community Indicators Victoria, McCaughey Centre: VicHealth Centre for the Promotion of Mental Health and Community Wellbeing, Melbourne School of Population Health, University of Melbourne in May 2014.\r\n\r\nDistances to many dozens of features as disparate as greengrocers, bus stops, tobacco sellers, and rail trails were calculated from meshblocks of mostly residential populations. These measures were then aggregated and grouped at the neighbourhood level. The table Geelong_BuiltEnvLookup.csv describes the variables and their meanings; these variables make up the GIS file and are also in Geelong_BuiltEnv.csv. In all there are 95 measures recorded for each suburb.\r\n\r\n>*Although all due care has been taken to ensure that these data are correct, no warranty is expressed or implied by the City of Greater Geelong or by the University of Melbourne in their use.*\r\n\r\nThe land use dataset was categorised into six different land uses: retail, \r\ncommercial, health/community, recreation, residential, and other. These categorisations were made on the basis of data supplied by the City of Greater Geelong and VicMap Planning Zones 2013. Land use mix was calculated using an entropy formula. The resulting land use mix measure is a value between 0 and 1, where 0 indicates homogenous land use (i.e. the entire suburb is the same land use) and 1 indicates heterogeneous land use (i.e. there are equal areas of each of the different types of land use of interest). \r\n\r\nDistances to sites were calculated along street centrelines. Site information was supplied by the City of Greater Geelong.\r\n\r\nNote that densities are often not spatial densities (eg. number per hectare) but, rather, represent number of sites per population measure or per kilometre of roads.

本建成环境清单（Built Environment Inventory）数据集展示了生活便利设施的可达性与潜在健康风险。

本数据集源自"健康携手吉隆（Healthy Together Geelong）"发起的一项研究项目，于2014年5月由维多利亚社区指标项目（Community Indicators Victoria）、麦考伊中心（McCaughey Centre）：维多利亚心理健康与社区福祉促进中心（VicHealth Centre for the Promotion of Mental Health and Community Wellbeing）、墨尔本大学人口健康学院（Melbourne School of Population Health, University of Melbourne）采用成熟的专有方法计算生成。

研究以大多为居住人口的统计区块（meshblock）为基础，计算了数十种迥异设施的可达距离，涵盖果蔬店、公交站点、烟草销售点与休闲步道等。随后将这些指标在街区层面进行聚合与分组。"Geelong_BuiltEnvLookup.csv"对各变量及其含义进行了详细说明，这些变量构成了地理信息系统（GIS）文件的核心内容，同时也可在"Geelong_BuiltEnv.csv"中获取。每个郊区共计记录95项指标。

*尽管已尽万全之力确保本数据集的准确性，但大吉朗市政府（City of Greater Geelong）与墨尔本大学均不对本数据的使用作出任何明示或默示的担保。*

本土地利用数据集被划分为六大类：零售用地、商业用地、医疗/社区用地、休闲用地、居住用地及其他用地。该分类基于大吉朗市政府提供的数据与2013年VicMap规划分区（VicMap Planning Zones 2013）完成。土地利用混合度通过熵公式计算得出，其取值范围为0至1：取值为0代表土地利用均质化（即整个郊区均为同一种用地类型），取值为1则代表土地利用异质化（即各目标用地类型的面积均等）。

设施可达距离沿街道中心线进行计算，相关设施信息由大吉朗市政府提供。

请注意，本数据集所采用的密度指标通常并非空间密度（例如每公顷数量），而是指每单位人口或每公里道路对应的设施数量。
