资源简介：
The GIS data (polygons) were derived from annexation information found on a printed map originally compiled by the Edmonton Regional Planning Commission in [1974]. The map was georeferenced and the annexation boundaries digitized within the ArcGIS 10.1 software environment. Annexations post-1974 were derived from available GIS data outlining the current city boundary of Edmonton, coinciding with the 1982 annexation. The layers can also be explored using CartoDB - Annexations
