UNI-CEN Boundaries (CBF-Original Shorelines) - Census Subdivision (CSD) - 1931 - 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）可助力实现UNI-CEN人口普查数据表的空间制图匹配。本系列针对不同应用场景提供多种格式的边界数据：Esri形状文件（Esri Shapefile，简称SHP）、geoJson格式文件以及文件地理数据库（File Geodatabase，简称FGDB）。其中SHP与FGDB格式文件提供两种投影坐标系：用于印刷制图的NAD83加拿大空间参考系（NAD83 CSRS），以及面向Web应用的世界大地测量系统1984（WGS84），而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、数据生成方法及使用方式，请查阅https://borealisdata.ca/dataverse/unicen_docs处的官方文档。若需了解该项目更多详情，请访问https://observatory.uwo.ca/unicen。
