UNI-CEN Boundaries (CBF-Original Shorelines) - Census Subdivision (CSD) - 1881 - File Geodatabase format (WGS84 / EPSG:4326)

The UNI-CEN Digital Boundary File Series facilitates the mapping of UNI-CEN census data tables. Boundaries are provided in multiple formats for different use cases: Esri Shapefile (SHP), geoJson, and File Geodatabase (FGDB). SHP and FGDB files are provided in two projections: NAD83 CSRS for print cartography and WGS84 for web applications. The geoJson version is provided in WGS84 only. The UNI-CEN Standardized Census Data Tables are readily merged to these boundary files. For more information about file sources, the methods used to create them, and how to use them, consult the documentation at https://borealisdata.ca/dataverse/unicen_docs.

UNI-CEN 数字边界文件系列可助力 UNI-CEN 普查数据表的空间制图工作。针对不同应用场景，该边界数据提供了多种格式：Esri形状文件（Esri Shapefile，缩写SHP）、geoJson格式以及文件地理数据库（File Geodatabase，缩写FGDB）。其中SHP与FGDB格式文件提供了两种投影坐标系：用于印刷制图的北美大地测量83 加拿大空间参考系统（NAD83 CSRS），以及用于Web应用的世界大地测量系统84（WGS84）；geoJson格式仅提供WGS84坐标系版本。UNI-CEN 标准化普查数据表可便捷地与上述边界文件实现关联整合。如需了解文件来源、制作方法及使用方式等更多信息，请查阅以下文档：https://borealisdata.ca/dataverse/unicen_docs。如需了解该项目的更多详情，请访问：https://observatory.uwo.ca/unicen。
