Canadian Spatial Reference System Online Database (CSRS Online Database)
The CSRS Online Database allows users direct access to the Canadian Active Control System products (CACS); the primary horizontal and vertical control networks archived on the Canadian Geodetic Information System (CGIS) and selected GSD software/data (GPSPace, NTv2 and GPS-H) and access to the CSRS - Precise Point Positioning (PPP) online GPS processing.
CSRS - Precise Point Positioning Service (PPP)
An online global service for GPS data post-processing that allows GPS users to submit single (code) or dual frequency (code/phase), static or kinematic observation data over the Internet and recover, using precise GPS Orbit and Clock information, enhanced positioning precisions in the Canadian Spatial Reference System NAD83CSRS and the International Terrestrial Reference Frame (ITRF).
Active Networks - Canadian Spatial Reference System
Passive Networks - Canadian Spatial Reference System
The Geodetic Survey Division maintains and provides access to the Canadian Spatial Reference System (CSRS) which is based on primary vertical and horizontal networks of groundbased survey control and other georeferencing networks.
Software
GPSPACE - GPS Positioning from ACS Clocks and Ephemerides Version 3.3 (Windows).
GPS-H - GPS Height Transformation Package. Convert NAD83CSRS ellipsoidal heights to CGVD28 orthometric heights.
NTv2 - National Transformation Software Package: NAD27 - NAD83. Enter the geographic coordinates of the point for which you want to apply the transformation. Select the direction of the transformation.
GSRUG - Geodetic Survey Routine, UTM/TM to/from Geographic coordinate conversion. You can compute either Universal Transverse Mercator (UTM) coordinates from the geographic latitude and longitude of a point or the reverse conversion.
INDIR - Geodetic Direct and Inverse Computation. You can perform either geodetic direct or inverse computations.
TRNOBS - may be used to transform geodetic coordinates between NAD83CSRS and all official realizations of the International Terrestrial Reference Frame (ITRF).
