News: Contribute to passive control maintenance
Would you like to provide your 3D positions for existing monument control through our CSRS-PPP application?
This is part of a pilot project to study the feasibility of using CSRS-PPP submissions to maintain the existing passive control monuments.
This allows users of the Canadian Reference system to:
- Obtain information on the usage of passive control in your work area
- Provide improved and repeated 3D positions for passive monuments
What we need from you:
- Official control marker station name for easy storage
- Authorization to publish the solution on geodetic reference system website (or other federally supported dissemination of passive control online application)
See ‘More options’ on our CSRS-PPP online submission page.
Geodetic reference systems stem from the need to provide a consistent and integrated reference surface for data analysis. Applications include surveying, mapping, navigation, remote sensing and mineral exploration amongst others. At the national level, NRCan maintains the Canadian Spatial Reference System (CSRS), through the use of the North American Datum of 1983 (NAD83CSRS), which is the adopted standard in Canada.
This site provides end-users with the geodetic data and tools they need for a range of commercial and private uses. One of the most popular services is the online CSRS-PPP service, which provides centimetre-accuracy positioning in either NAD83(CSRS) or ITRF using GNSS technologies.
