UNI-CEN Boundaries (CBF-Original Shorelines) - Census Tract (CT) - 1976 - 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 数字化边界文件系列（UNI-CEN Digital Boundary File Series）可支撑 UNI-CEN 普查数据表的空间制图匹配工作。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，SHP）、geoJson 以及文件地理数据库（File Geodatabase，FGDB）。其中，SHP 与 FGDB 格式数据配备了两种投影坐标系：适用于印刷制图的 NAD83 CSRS，以及适用于Web应用的 WGS84；geoJson 格式数据仅提供 WGS84 坐标系版本。UNI-CEN 标准化普查数据表（UNI-CEN Standardized Census Data Tables）可与本边界文件集轻松实现合并关联。如需了解文件来源、数据生成方法及使用方式等更多信息，请查阅 https://borealisdata.ca/dataverse/unicen_docs 处的文档。如需了解该项目的更多详情，请访问 https://observatory.uwo.ca/unicen。
