UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Subdivision (CSD) - 1881 - Esri Shapefile 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人口普查数据表与空间边界的匹配映射。该系列提供多种格式的空间边界文件以适配不同应用场景：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格式文件提供两种坐标系投影：用于印刷制图的北美大地测量系统1983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格式版本仅提供世界大地测量系统1984（WGS84）坐标系投影。UNI-CEN标准化人口普查数据表可便捷地与上述边界文件完成数据融合。如需了解文件来源、制作方法及使用方式等更多信息，请查阅以下链接中的文档：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。
