Passive Control Networks

The Passive Control Networks include the Canadian Base Network (NAD83CSRS), the High Precision 3D Network (NAD83CSRS) as well as the Vertical (CGVD28) and Horizontal (NAD83) Control Networks.

Information about selected stations can be downloaded in the CSV, KML, or PDF formats from the "Station information" panel. To select stations, use the checkboxes in the Map or the Stations list. Search results will be shown on the map and added to the stations list.

You can search for a station by name in the Find a station tab. It is also possible to search a station from the Network search tab. For networks searches, you can define an area in four ways:

1. Changing the visible map area
2. NTS Map Sheet
3. Radial search
4. Geographic Bounds
