UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Metropolitan Area (CMA) - 1971 - File Geodatabase 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数字边界文件系列可助力UNI-CEN人口普查数据表的空间映射与制图。该边界文件提供多种格式以适配不同应用场景：Esri形状文件（Esri Shapefile）、地理JSON（geoJson）以及文件地理数据库（File Geodatabase，FGDB）。其中SHP与FGDB格式文件提供两种投影参考系统：用于印刷制图的北美大地测量基准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）；地理JSON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这些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https://borealisdata.ca/dataverse/unicen_docs处的文档。如需了解该项目的更多详情，请访问https://observatory.uwo.ca/unicen。
