Property Property



Authority to use public land is granted through dispositions issued under the provisions of the Public Lands Act. A disposition is a land use contract that gives specific rights to a land or resource user (e.g. lease, license, or permit).

The DIDs mapping is a fully GIS dataset available in 1:250 NTS tiles or as a seamless provincial coverage. It contains several types of active dispositions and covers all public lands in Alberta. Examples include: LOC, MSL, EZE, PLA, GRP, etc. Integration of new dispositions and amendments occur within 2-3 business days of approval and updates are released to industry on a daily basis.


The access subscription price is $2400 per year, which includes unlimited downloads from our Virtual Order Desk. Municipalities or other 'defined' service areas are available for $240 per year.

Transactional access fees are $120 for the first 250K file plus $30 for each additional file (within the same transaction).

Additional FTP Service to automate daily DIDs updates: $600 per year.

Product Features:

The DIDs product features all major types of dispositions on Alberta's public lands. It is an integrated mapping representation of disposition plans as they are applied for and approved, which is tied to the Alberta Township System Version 4.1 (ATS V4.1) grid.

The DIDs product contains three shape files: Application (_APPL), LSAS Conflict (_LCON), and Historical (_HIST), and a discrepancy report database with four tables: ATS Township, Discrepancy Report, Discrepancy Codes, and Dispositions not mapped.

APPLICATION (main theme): Contains all dispositions as they were applied for and approved.

CONFLICT: Dispositions where LSAS information shows the activity in a different quarter section than the application.

HISTORICAL: All cancelled activities, and activities that are replaced by an amendment since August 1, 2005. (Available in SHP format only)

DISCREPANCY DATABASE: Identifies plans that conflict with adjacent plans or have insufficient detail for mapping purposes. As the GOA resolves any discrepancies, they are updated in DIDs.

Product Details:

Disposition mapping is available in both 250K NTS tiles and seamless provincial coverage in GIS format (ESRI SHP/Geographic) or 250K tiles in AutoCAD (DWG/10TM) format. NAD83 is the datum for all Disposition mapping.

DIDs in SHP format is updated daily, and DWG is updated monthly.
