UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Tract (CT) - 1971 - 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实现UNI-CEN人口普查数据表与空间边界的制图匹配。针对不同应用场景，该系列提供多种格式的边界数据：Esri形状文件（Esri Shapefile，简称SHP）、geoJson以及文件地理数据库（File Geodatabase，简称FGDB）。SHP与FGDB格式文件配备两种坐标投影：用于印刷制图的NAD83加拿大空间参考系统（NAD83 CSRS），以及适用于Web应用的世界大地测量系统1984（WGS84）。geoJson格式版本仅提供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该系列边界文件进行合并整合。若需了解文件来源、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。若需了解该项目的更多详情，请访问：https://observatory.uwo.ca/unicen。
