DCM_CityMapAlterations

The Digital City Map (DCM) data represents street lines and other features shown on the City Map, which is the official street map of the City of New York. The City Map consists of 5 different sets of maps, one for each borough, totaling over 8000 individual paper maps. The DCM datasets were created in an ongoing effort to digitize official street records and bring them together with other street information to make them easily accessible to the public. The Digital City Map (DCM) is comprised of seven datasets; Digital City Map, Street Center Line, City Map Alterations, Arterial Highways and Major Streets, Street Name Changes (areas), Street Name Changes (lines), and Street Name Changes (points).

All of the Digital City Map (DCM) datasets are featured on the <a href="https://streets.planning.nyc.gov/about">Streets App</a>

All previously released versions of this data are available at BYTES of the <a href="https://www1.nyc.gov/site/planning/data-maps/open-data/bytes-archive.page?sorts[year]=0">BIG APPLE- Archive </a>

Updates for this dataset, along with other multilayered maps on NYC Open Data, are temporarily paused while they are moved to a new mapping format. Please visit https://www.nyc.gov/site/planning/data-maps/open-data/dwn-digital-city-map.page to utilize this data in the meantime.

《数字城市地图》（DCM）数据集代表了城市地图上展示的街道线路及其他特征，该城市地图是纽约市官方的街道地图。城市地图包括五个不同的地图系列，每个区一个，总计超过8000张单独的纸质地图。《数字城市地图》（DCM）数据集是在持续数字化官方街道记录并将其与其他街道信息整合，以便公众易于访问的努力中创建的。数字城市地图（DCM）由七个数据集组成；数字城市地图、街道中心线、城市地图变更、主要干道及大街、街道名称变更（区域）、街道名称变更（线路）和街道名称变更（点）。所有《数字城市地图》（DCM）数据集均可在《街道应用》（[Streets App](https://streets.planning.nyc.gov/about)）上找到。此数据集所有先前发布的版本均可在《大苹果》（[BYTES of the BIG APPLE](https://www1.nyc.gov/site/planning/data-maps/open-data/bytes-archive.page?sorts[year]=0)）存档中找到。由于这些数据正在迁移至新的地图格式，因此对这一数据集及其它多层级地图在纽约市开放数据上的更新已暂时暂停。在此期间，请访问[数字城市地图页面](https://www.nyc.gov/site/planning/data-maps/open-data/dwn-digital-city-map.page)以利用这些数据。
