The Management of Survey Control Operations & Tasks (MASCOT) system consists of a network of over 50,000 survey control monuments situated in the valleys and mountains throughout British Columbia. This network of monuments was established from mapping and control surveys conducted over the last century.
During the 1960s, through a partnership between the B.C. Provincial Government and local governments, the physical control system was extended to developing areas. MASCOT is a database of the provincial control survey's physical system and provides published coordinates and elevations and related data for public access and use.
Access the Management of Survey Control Operations & Tasks. A MASCOT account is required.
A daily update occurs when any attribute of a Geodetic Control Marker (GCM) is changed. This attribute may be horizontal coordinates, elevation, marker location description, marker condition, etc. Any change to a GCM is reflected in all "Textual" and "Graphics" based access of data, available to the user on the day following any change. The daily update ensures that data is always up-to-date. Last Update: Wednesday December 6, 2017.

Sketch Cards or Marker Location Diagrams are available as downloadable GIF files via the above MASCOT queries. For more information on sketch card access and printing click here.
Datums are reference systems that define a geodetic network. Two different datums are used in North America:
The National Transformation Version 2 (NTv2) software and data package provides a national standard for transforming coordinates between NAD27 and NAD83.
NTv2 software is provided by Natural Resources Canada. There is no cost to use NTv2.
