UNI-CEN Boundaries (CBF-Original Shorelines) - Census Subdivision (CSD) - 1921 - 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）可辅助开展UNI-CEN人口普查数据表的空间制图匹配工作。本系列针对不同应用场景提供了多种格式的边界数据：Esri形状文件（Esri Shapefile，缩写SHP）、geoJson格式文件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NAD83 CSRS坐标系，以及适用于Web应用的WGS84坐标系；geoJson格式文件仅提供WGS84坐标系版本。UNI-CEN标准化人口普查数据表可便捷地与本系列边界文件完成合并匹配。如需了解文件来源、数据生成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。
