UNI-CEN Boundaries (CBF-Original Shorelines) - Census Subdivision (CSD) - 1861 - File Geodatabase format (NAD83 CSRS / EPSG:3348)

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匹配。该系列边界数据提供多种格式以适配不同应用场景：Esri Shapefile（SHP）、geoJson以及文件地理数据库（File Geodatabase，FGDB）。其中，SHP与FGDB格式的数据提供两种投影方案：用于印刷制图的北美大地基准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1984（WGS84）；而geoJson格式的数据仅采用WGS84投影。UNI-CEN标准化普查数据表可便捷地与这些边界文件进行关联整合。如需了解文件来源、数据制作方法及使用方式，请查阅https://borealisdata.ca/dataverse/unicen_docs 中的文档。若需了解该项目的详细信息，请访问https://observatory.uwo.ca/unicen。
