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>

本数据集为一中型向量多边形数据集，展示了爱尔兰地区乡镇边界。该数据集现已公开发布于OpenData平台。OSNI大比例尺乡镇数据集由一系列乡镇边界构成的多边形数据集组成。乡镇是爱尔兰独有的古老土地测量方法，对于家谱研究具有重要意义。这些小型土地区域面积从数英亩至数英亩不等。数据源自OSNI大比例尺数据库，经过拓扑清理和属性标注，以形成无缝的数据集。<div><br /></div>请注意，对于Open Data NI用户：Esri Rest API功能正常，不会在浏览器中自动打开，但可复制并用于桌面和Web地图。
