UNI-CEN Boundaries (DBF-Original Shorelines) - Census Subdivision (CSD) - 1991 - Esri Shapefile 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可辅助完成 UNI-CEN 普查数据表的空间制图匹配。本系列边界文件提供多种格式以适配不同应用场景：Esri 形状文件（Esri Shapefile，SHP）、地理JSON（geoJson）以及文件地理数据库（File Geodatabase，FGDB）。SHP与FGDB文件提供两种投影坐标系：用于印刷制图的NAD83 CSRS，以及用于网页应用的WGS84；geoJson版本仅提供WGS84坐标系下的数据。UNI-CEN 标准化普查数据表可便捷地与该系列边界文件完成关联匹配。如需了解文件来源、制作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。
