Management of Survey Control Operations & Tasks (MASCOT)

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.

How to Use

Access to MASCOT is free of charge. Submit an application to get a MASCOT account:

Search for a geodetic control monument to get its final coordinates, using either text or spatial queries:

Daily updates occur when any attribute of a geodetic control marker is changed.

Transform Coordinates

Datums are reference systems that define a geodetic network. Two different datums are used in North America:

  • North American Datum of 1927 (NAD27)
  • North American Datum of 1983 (NAD83)

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.
