UNI-CEN Boundaries (CBF-Original Shorelines) - Census Subdivision (CSD) - 2021 - 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（UNI-CEN Digital Boundary File Series）可支持UNI-CEN人口普查数据表的空间匹配制图。针对不同应用需求，该边界数据集提供多种格式：Esri形状文件（Esri Shapefile，SHP）、地理JSON（geoJson）以及文件地理数据库（File Geodatabase，FGDB）。SHP与FGDB格式文件配备两种投影坐标系：用于印刷制图的NAD83 CSRS，以及适用于Web应用的WGS84。geoJson格式版本仅提供WGS84坐标系下的数据。UNI-CEN标准化人口普查数据表可与上述边界文件实现便捷关联匹配。如需了解文件来源、制作方法及使用方式等详细信息，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。
