Geodetic Survey Division - Online Data
by Neoteric at 1:12 pm EDT, Aug 30, 2004

] 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),
] selected Geodetic Survey Division software/data,
] (GPSPace, NTv2 and GPS·H) and access to the CSRS -
] Precise Point Positioning (PPP) online GPS processing.

Okay so here's the deal. Setup your gps. Stand very still. Collect data from GPS to computer for about an hour. Submit data to these canadians. They do ionosphere corrections on the data. Email you back exact co-ordinates. Typical corrections are sub-meter with a lower practical bound of 1cm.

Geocache this biatch.
