UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Division (CD) - 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）可助力实现UNI-CEN普查数据表与空间边界的匹配制图。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以及文件地理数据库（File Geodatabase，缩写FGDB）。SHP与FGDB格式数据提供了两种投影坐标系：用于印刷制图的NAD83加拿大参考系统（NAD83 CSRS），以及用于Web应用的世界大地测量系统1984（WGS84）。geoJson格式数据仅提供WGS84坐标系版本。UNI-CEN标准化普查数据表可便捷地与本系列边界文件完成数据合并。若需了解文件来源、数据制作方法及使用方式，请查阅以下文档：https://borealisdata.ca/dataverse/unicen_docs。若需了解该项目更多详情，请访问：https://observatory.uwo.ca/unicen。
