UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Metropolitan Area (CMA) - 2021 - geojson 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数字化边界文件系列可辅助完成UNI-CEN普查数据表的空间制图匹配。针对不同使用场景，该系列提供多种格式的边界文件：Esri形状文件（Esri Shapefile，SHP）、geoJson格式以及文件地理数据库（File Geodatabase，FGDB）。其中SHP与FGDB格式文件提供两种投影坐标系：北美大地基准83 加拿大空间参考系统（NAD83 CSRS）适用于印刷制图，世界大地测量系统84（WGS84）适用于网页应用。geoJson格式仅提供WGS84坐标系下的数据。UNI-CEN标准化普查数据表可便捷地与该系列边界文件完成整合匹配。若需了解文件来源、制作方法及使用方式，请查阅https://borealisdata.ca/dataverse/unicen_docs处的文档。若需了解该项目更多详情，请访问https://observatory.uwo.ca/unicen。
