WSDOT - Survey Monuments

The Geodetic Survey Section within WSDOT has installed and maintains a majority of the primary (Geodetic) survey control used by the Department of Transportation in its ongoing construction and road maintenance programs. As part of this process the Survey Section maintains a Survey-Monuments database. The gis file is updated nightly and sourced from a sql database. Updates to the sql database are irregular but the gis data will be as recent as the most current version of the sql database. This data is provided for mapping purposes only. This data does not contain the complete range of attributes and information that are available for each station within the database. If you need the physical geodetic coordinates for a monument, please obtain it from the database.华盛顿州运输部（Washington State Department of Transportation, WSDOT）下属的大地测量科，负责安装并维护该部在持续建设与道路养护项目中使用的绝大多数核心大地测量（Geodetic）控制网点。作为此项工作的组成部分，该测量科维护着一套测量地标（Survey-Monuments）数据库。其配套的地理信息系统（GIS）文件每日夜间更新，数据源为结构化查询语言（SQL）数据库。SQL数据库的更新并无固定周期，但GIS数据的时效性将与SQL数据库的最新版本保持同步。本数据集仅用于制图用途，未涵盖该数据库中各测量站点的全部属性与相关信息。若需获取某测量地标实体的大地测量坐标，请直接从该数据库中提取。
