UNI-CEN Boundaries (CBF-Harmonized Shorelines) - Census Tract (CT) - 1986 - 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 数字边界文件系列（UNI-CEN Digital Boundary File Series）可助力实现UNI-CEN普查数据表与对应地理边界的匹配制图。本系列针对不同应用场景提供多种格式的边界数据：Esri 形状文件（SHP）、geoJson 以及文件地理数据库（FGDB）。其中SHP与FGDB格式文件提供两种坐标系投影版本：分别为用于印刷制图的NAD83 加拿大空间参考系统（NAD83 CSRS），以及用于Web应用的世界大地测量系统84（WGS84）。geoJson格式仅提供WGS84坐标系下的版本。UNI-CEN 标准化普查数据表可便捷地与上述边界文件进行关联合并。如需了解文件来源、制作方法及使用方式，请查阅以下文档：https://borealisdata.ca/dataverse/unicen_docs。如需了解该项目更多详情，请访问：https://observatory.uwo.ca/unicen。
