UNI-CEN Boundaries (DBF-Original Shorelines) - Census Subdivision (CSD) - 1991 - File Geodatabase 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）可实现UNI-CEN人口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多种格式的空间边界数据：Esri形状文件（Esri Shapefile，简称SHP）、地理JSON（geoJson）以及文件地理数据库（File Geodatabase，简称FGDB）。其中SHP与FGDB格式数据提供两种投影坐标系：适用于印刷制图的NAD83 CSRS坐标系，以及面向Web应用的WGS84坐标系。geoJson格式数据仅提供WGS84坐标系版本。UNI-CEN标准化人口普查数据表可便捷地与本系列边界文件进行合并关联。如需了解数据文件来源、制作流程及使用方法，请查阅https://borealisdata.ca/dataverse/unicen_docs处的官方文档。如需了解该项目更多详情，请访问https://observatory.uwo.ca/unicen。
