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，展示了土地边界。该数据集公开发布于OpenData平台。OSNI大规模土地数据集由多边形组成，包含了土地边界信息。土地边界是一种古老的土地测量方法，仅存在于爱尔兰，对于族谱研究具有重要意义。这些小规模的土地面积可以从数英亩不等。数据源自OSNI大规模数据库，经过拓扑清理和属性赋值，构建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Web地图。
