Geo-spatial referencing
Last updated on June 27, 2024Geospatial referencing provides the geographic coordinate system for all surveying and mapping applications. Learn how it's used in forestry, GIS databases, managing vehicle dispatching and more.
A new system is being implemented which will result in changes to benchmark elevations across B.C.
B.C. Active Control System
The B.C. Active Control System (BCACS) sets up GNSS infrastructure to pinpoint locations in British Columbia. It helps people find their positions in real-time, which is useful for many different purposes. The BCACS group in the government maintains the standards for this system.
Geodetic database
British Columbia’s geospatial reference database consists of two components. The Management of Survey Control Operations & Tasks (MASCOT) manages physical location data with monuments. The Master Active Control System handles satellite-based information. The government manages this database to keep the data safe and make sure it's accurate.
Geoid model data
The geoid model helps measure heights above sea level in British Columbia. The government processes survey data to figure out exact coordinates and elevations for storing and using this information.
Vertical reference system
Vertical or height reference systems measure how high or low something is compared to sea level. A new system is being implemented which will result in changes to benchmark elevations across B.C.
