OSNI Open Data - 50K Boundaries - Townlands

Mid scale vector polygon dataset showing townland boundaries. Published here for OpenData. The OSNI Largescale Townlands is a polygon dataset consisting of the Townland boundaries. Townlands are an ancient method of land measurement found only in Ireland and can be very important in genealogical research. These small areas of land can vary in size from a few acres upwards. The data has been derived from OSNI Largescale database and has been topologically cleansed and attributed to create a seamless dataset.<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>

本数据集为中等规模矢量多边形数据集，展示了城镇边界。数据集在此公开发布，旨在开放数据领域。OSNI 大比例尺城镇边界数据集由城镇边界构成的多边形数据集组成。城镇边界是一种古老的土地测量方法，仅在爱尔兰发现，对于家谱研究可能具有重要意义。这些小块土地的面积可以从几英亩不等，直至更大。数据源自 OSNI 大比例尺数据库，经过拓扑清理和属性赋值，形成了一个无缝的数据集。<div><br /></div>请注意，对于 Open Data NI 用户：Esri REST API 并未损坏，它不会在浏览器中自动打开，但可以复制并用于桌面和网络地图。
