UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Metropolitan Area (CMA) - 1971 - 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 数字边界文件系列（UNI-CEN Digital Boundary File Series）可支撑 UNI-CEN 普查数据表的空间制图作业。该边界文件针对不同应用场景提供了多种格式：Esri 形状文件（Esri Shapefile，SHP）、geoJson 以及文件地理数据库（File Geodatabase，FGDB）。其中，SHP 与 FGDB 格式文件配备两种投影坐标系：适用于印刷制图的 NAD83 CSRS，以及适用于网络应用的 WGS84；geoJson 格式版本仅提供 WGS84 坐标系下的文件。UNI-CEN 标准化普查数据表可便捷地与该系列边界文件完成关联匹配。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。
