GIS Data
The ALR boundaries for the province have been digitized into GIS (Geographic Information Systems)
format, rectifying the existing ALR boundaries to provincial standard geo-referenced digital data:
- TRIM for planimetric base features such as water bodies, roads, etc; and
- cadastral data from the Integrated Cadastral Information Society (ICIS). Where this is not available, Crown Land Registry Services parcel-based data, Cadastral Data Management System (CDMS) is used.
Each ALR boundary segment carries attributes to describe what the boundary aligns with. This includes
the type of feature the boundary follows (e.g. property boundary, river) and the data source that feature was captured from.
The digital ALR layer may not be aligned to the most current property boundary data in some areas. If there is any doubt as to a property's location relative to the ALR, consult
the official ALR map. The ALC does not have historical ALR boundaries in GIS format.
If you have GIS capability you can download a shapefile of the ALR boundary here. Please read the README file before
using the data.
