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，展现了城镇界限。该数据集已在此处公开发布，旨在支持开放数据。OSNI 大比例尺城镇数据集由城镇界限的多边形数据构成。城镇界限是一种古老的土地测量方法，仅存在于爱尔兰，对于家谱研究具有重要意义。这些小块土地的面积从数英亩不等，可向上扩展。数据源自 OSNI 大比例尺数据库，经过拓扑清洗和属性归一化处理，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，它不会在网页浏览器中自动打开，但可以复制并用于桌面和网络地图中。
