摆脱地理信息科学中的图钉范式：（重新）呈现国家犯罪数据

2011年，内政部释放了警察。该网站提供了英格兰、威尔士和北爱尔兰全国范围内近期犯罪数据的高分辨率地图。通过这项免费服务，犯罪被绘制在谷歌地图上，以点表示，分辨率低到街道级别。然而，为了保持机密性和遵守数据披露法规，个人层面的犯罪被汇总到代表一系列街道上的事件集群的点上。然而，通过汇总，将犯罪作为点表示就会出现问题，从而导致犯罪发生地点的虚假精确。鉴于公众对此类信息的明显敏感性，犯罪数据的适当表示具有社会必要性，因此，在本文中，我们提出了一种将“点”犯罪事件转换为与街道网络地理相关的新表示形式的方法；在另一个国家犯罪地图门户网站http://www.policestreets.co.uk上展示这些结果。
In 2011 the Home Office released the police.uk website, which provided a high‐resolution map of recent crime data for the national extents of England, Wales and Northern Ireland. Through this free service, crimes were represented as points plotted on top of a Google map, visible down to a street level of resolution. However, in order to maintain confidentiality and to comply with data disclosure legislation, individual‐level crimes were aggregated into points that represented clusters of events that were located over a series of streets. However, with aggregation the representation of crimes as points becomes problematic, engendering spurious precision over where crimes occurred. Given obvious public sensitivity to such information, there are social imperatives for appropriate representation of crime data, and as such, in this paper we present a method of translating the ‘point’ crime events into a new representational form that is tied to street network geography; presenting these results in an alternate national crime mapping portal http://www.policestreets.co.uk.
