UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Tract (CT) - 1971 - Esri Shapefile 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为 UNI-CEN 人口普查数据表的空间制图提供支持。本系列针对不同应用场景提供了多种边界数据格式：Esri Shapefile（SHP）、geoJson 以及 文件地理数据库（File Geodatabase，FGDB）。其中 SHP 与 FGDB 格式文件提供了两种投影坐标系：适用于印刷制图的 NAD83 CSRS 坐标系，以及面向网络应用的 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进行关联融合。如需了解文件来源、制作方法及使用方式等更多详情，请查阅以下文档：https://borealisdata.ca/dataverse/unicen_docs。如需了解该项目的更多信息，请访问：https://observatory.uwo.ca/unicen。
