UNI-CEN Boundaries (DBF-Original Shorelines) - Census Metropolitan Area (CMA) - 1991 - Esri Shapefile 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）可为UNI-CEN人口普查数据表的空间匹配制图提供支撑。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，SHP）、geoJson以及文件地理数据库（File Geodatabase，FGDB）。其中SHP与FGDB格式文件提供两种坐标投影：用于印刷制图的NAD83加拿大空间参考系统（NAD83 CSRS），以及用于Web应用的WGS84坐标系统；geoJson格式仅提供WGS84坐标投影版本。UNI-CEN标准化人口普查数据表可便捷地与上述边界文件进行关联合并。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。若需了解该项目的更多详情，请访问：https://observatory.uwo.ca/unicen。
