UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Tract (CT) - 2021 - geojson 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数字化边界文件系列（UNI-CEN Digital Boundary File Series）可助力UNI-CEN人口普查数据表的地理制图工作。针对不同应用场景，该边界数据集提供多种格式：Esri形状文件（Esri Shapefile，SHP）、geoJson格式以及文件地理数据库（File Geodatabase，FGDB）。其中，SHP与FGDB格式文件包含两种投影坐标系：适用于印刷制图的NAD83加拿大空间参考系（NAD83 CSRS），以及适用于Web应用的WGS84坐标系；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上述边界文件进行关联整合。如需了解文件来源、制作方法及使用方式等更多细节，请查阅https://borealisdata.ca/dataverse/unicen_docs处的官方文档。如需了解该项目的更多相关信息，请访问https://observatory.uwo.ca/unicen。
