UNI-CEN Boundaries (CBF-Original Shorelines) - Census Division (CD) - 1941 - 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）可用于辅助完成UNI-CEN普查数据表的空间制图匹配。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，缩写SHP）、geoJson以及文件地理数据库（File Geodatabase，缩写FGDB）。SHP与FGDB格式文件提供了两种投影坐标系：适用于印刷制图的NAD83 CSRS，以及面向Web应用的WGS84。geoJson格式版本仅提供WGS84坐标系下的数据。UNI-CEN标准化普查数据表（UNI-CEN Standardized Census Data Tables）可便捷地与本系列边界文件进行合并适配。如需了解文件来源、数据制作方法及使用方式等更多信息，请查阅以下文档：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。
