UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Tract (CT) - 1971 - 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 数字边界文件系列可辅助完成 UNI-CEN 人口普查数据表的空间制图匹配。针对不同应用场景，该边界数据提供多种格式：Esri 形状文件（SHP）、geoJson 格式以及文件地理数据库（FGDB）。其中，SHP 与 FGDB 格式文件配备两种投影坐标系：用于印刷制图的 NAD83 CSRS 坐标系，以及适配网络应用的 WGS84 坐标系；geoJson 格式仅提供 WGS84 坐标系版本。UNI-CEN 标准化人口普查数据表可便捷地与该系列边界文件完成关联整合。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。
