OSNI Open Data - Coverage Grid - 50K

This shows the location of each of our 50K tiles. The 50K Grid is published here for Open Data and can be used as a reference system for the download of the 50m DTM. The OSNI Largescale grid is referenced to the Irish Grid, with all of Northern Ireland being covered by a grid of 17,335 tiles. Urban areas are covered by 1:1250 tiles and rural areas at 1:2500. Each 1:1250 tile covers an area of 0.6 km x 0.4 km and each 1:2500 tile covers an area of 1.2 km x 0.8 km.<div><br /></div><div>Please Note for Open Data NI Users: Esri Rest API is not Broken, it will not open on its own in a Web Browser but can be copied and used in Desktop and Webmaps<br /></div>本数据集展示了我方5万幅瓦片的空间分布位置。本次公开的50K格网（50K Grid）面向开放数据场景发布，可作为下载50米分辨率数字地形模型（DTM, Digital Terrain Model）的参考坐标系。 OSNI大比例尺格网以爱尔兰格网（Irish Grid）为基准，北爱尔兰全境由17335幅瓦片组成的格网覆盖。其中城市区域采用1:1250比例尺瓦片，农村区域采用1:2500比例尺瓦片。单幅1:1250比例尺瓦片的覆盖范围为0.6千米×0.4千米，单幅1:2500比例尺瓦片的覆盖范围为1.2千米×0.8千米。 致开放数据北爱尔兰（Open Data NI）用户请注意：Esri Rest API 并未出现故障，其无法直接在网页浏览器中单独启动，但可复制后在桌面端及网页地图中正常使用。
