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
- Crown Land Registry
Services parcel-based data, Cadastral Data Management System (CDMS) or large scale cadastral from the Integrated Cadastral
Information Society (ICIS).
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 is not 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.
Some of the GIS data is considered provisional, and is not considered the official representation
of the ALR boundary. See Status of ALR Mapping for a list of areas which still have their official ALR maps produced
manually, and which have them produced by GIS.
If you have GIS capability you can download a shapefile of the ALR boundary from the
following ftp site, in the folder Public/Outgoing/Shapefiles. Please read the README file before
using the data.
