UNI-CEN Boundaries (CBF-Original Shorelines) - Census Tract (CT) - 2001 - 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实现 UNI-CEN 人口普查数据表的空间制图关联。针对不同应用场景，本系列提供多种格式的地理边界文件：Esri Shapefile（SHP）、geoJson 以及文件地理数据库（File Geodatabase，FGDB）。其中 SHP 与 FGDB 格式文件提供两种投影坐标系：北美大地基准1983加拿大参考系（NAD83 CSRS）适用于印刷制图，世界大地测量系统1984（WGS84）适用于Web应用；geoJson 格式仅提供 WGS84 坐标系下的数据。UNI-CEN 标准化人口普查数据表可便捷地与这些边界文件进行关联合并。如需了解文件来源、生成方法及使用方式，请查阅以下文档：https://borealisdata.ca/dataverse/unicen_docs。如需了解该项目更多详情，请访问：https://observatory.uwo.ca/unicen。
