Crime Incidents in the Last 30 Days
收藏资源简介:
The dataset contains a subset of locations and attributes of incidents reported in the ASAP (Analytical Services Application) crime report database by the District of Columbia Metropolitan Police Department (MPD). Visit https://crimecards.dc.gov for more information. This data is shared via an automated process where addresses are geocoded to the District's Master Address Repository and assigned to the appropriate street block. Block locations for some crime points could not be automatically assigned resulting in 0,0 for x,y coordinates. These can be interactively assigned using the MAR Geocoder. On February 1 2020, the methodology of geography assignments of crime data was modified to increase accuracy. From January 1 2020 going forward, all crime data will have Ward, ANC, SMD, BID, Neighborhood Cluster, Voting Precinct, Block Group and Census Tract values calculated prior to, rather than after, anonymization to the block level. This change impacts approximately one percent of Ward assignments.
本数据集包含哥伦比亚特区大都会警察局(Metropolitan Police Department,简称MPD)在分析服务应用程序(Analytical Services Application,简称ASAP)犯罪报告数据库中上报的部分事件点位与属性数据。欲获取更多信息,请访问https://crimecards.dc.gov。本数据集通过自动化流程共享:所有地址均被地理编码至哥伦比亚特区主地址库(Master Address Repository,简称MAR),并分配至对应的街道街区。部分犯罪点位的街区位置无法自动分配,导致其x、y坐标为0,0。此类点位可借助MAR地理编码器(MAR Geocoder)完成交互式分配。2020年2月1日,本数据集对犯罪数据的地理分配方法进行了优化调整,以提升数据准确性。自2020年1月1日起,所有犯罪数据将在街区级匿名化处理前完成所属选区(Ward)、社区咨询委员会(Advisory Neighborhood Commission,简称ANC)、单人选区(Single Member District,简称SMD)、商业改善区(Business Improvement District,简称BID)、社区集群、投票区、街区组及人口普查区的相关数值计算,而非在匿名化处理后再进行此类计算。此次调整约影响1%的选区分配判定结果。
