UNI-CEN Boundaries (CBF-Original Shorelines) - Census Subdivision (CSD) - 1921 - 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（UNI-CEN Digital Boundary File Series）可助力UNI-CEN人口普查数据表的空间制图匹配。本系列边界文件针对不同应用场景提供多种格式：Esri形状文件（Esri Shapefile，缩写SHP）、地理JSON（geoJson）以及文件地理数据库（File Geodatabase，缩写FGDB）。其中SHP与FGDB格式文件提供两种投影方式：用于印刷制图的NAD83 CSRS投影，以及用于Web应用的WGS84投影；geoJson格式版本仅提供WGS84投影。UNI-CEN标准化人口普查数据表可便捷地与该系列边界文件进行整合关联。如需了解文件来源、制作方法及使用方式等更多详情，请查阅以下文档：https://borealisdata.ca/dataverse/unicen_docs。如需了解该项目更多信息，请访问：https://observatory.uwo.ca/unicen。
