Public Land Survey Corners and Remonumentations

This dataset comes from the Department of Licensing and Regulatory Affairs' Office of Land Survey and Remonumentation (OLSR). See Act 345 of 1990: State Survey and Remonumentation Act for more information. The system of record was queried for approved locations where grid coordinates were provided. Records with coordinates outside the state's geographical boundary were retained (34 locations). The columns "DMS LAT" and "DMS LONG" were added to the extraction table and populated with data from fields "Latitude N" and "Longitude W" and formatted to DMS2. The data was exported as feature class using geoprocessing tool "Convert Coordinate Notation," geographic coordinate system WGS 1984 Web Mercator (auxiliary sphere). This dataset was last updated June 6, 2022, with quarterly updates to begin in 2023. More Metadata本数据集源自执照与监管事务部土地测量与重测办公室（Office of Land Survey and Remonumentation, OLSR）。如需了解更多详情，请参阅1990年第345号法案《州测量与重测法案》。本次通过调取记录系统，获取已获批且附带网格坐标的点位数据，其中保留了坐标超出本州地理边界的记录共34条。于提取表中新增"DMS纬度（DMS LAT）"与"DMS经度（DMS LONG）"两列，从"北纬（Latitude N）"和"西经（Longitude W）"字段提取数据并填充至新增列，同时将坐标格式化为DMS2格式。本次数据通过地理处理工具"转换坐标表示法（Convert Coordinate Notation）"导出为要素类（feature class），采用的地理坐标系为WGS 1984 Web墨卡托（辅助球体）。本数据集最后更新时间为2022年6月6日，自2023年起将按季度开展更新工作。更多元数据（Metadata）
