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>

本数据集为一款中规模矢量多边形数据集，展示爱尔兰城镇边界。该数据集公开发布于OpenData平台。OSNI 大比例尺城镇数据集为由城镇边界构成的多边形数据集。城镇是爱尔兰独有的古老土地测量方法，对于族谱研究具有重要意义。这些小块土地的面积可从数英亩不等。数据源于OSNI 大比例尺数据库，经过拓扑清理和属性赋予，以构建无缝的数据集。<div><br /></div>请注意，对于Open Data NI用户：Esri Rest API并非损坏，它无法在网页浏览器中自动打开，但可复制并用于桌面和Web地图。
