Press Release

New Geoscience Data Repository released by Natural Resources Canada


On January 2, 2004, the Geological Survey of Canada, a component of Natural Resources Canada, released its web mapping application for public viewing and downloading of geophysical data as a contribution to the Earth Sciences Sector program, Consolidating Canada’s Geoscience Knowledge (CCGK).

Free viewing and downloading of national gridded geophysical data sets is now available online at http://gdr.nrcan.gc.ca//index_e.php. Data are delivered via a new web mapping application utilizing Geosoft’s Data Access Protocol (DAP) technology.

The web application combines a web map server interface with a data delivery system for gridded aeromagnetic, gravity and radiometric data. Clients can interactively select an area, specify an appropriate projection, and download the data in a large number of standard formats, all at no cost.

The application was developed and implemented using Geosoft Inc.’s DAP (Data Access Protocol) technology. It is the first stage in a CCGK project to deliver geophysical and geochemical data online. Later stages will deliver additional gridded data sets, georeferenced images, and profile data, as well as improvements in the functionality of the interface.

The following gridded data sets are currently available at http://gdr.nrcan.gc.ca//index_e.php.

Data type Area Field/variable Resolution Date

Aeromagnetic Canada Residual total field 1000 m October 2002
Aeromagnetic Canada Residual total field 200 m November 2003
Gravity Canada Bouguer on land,
Free air offshore
2000 m November 2003
Radioactivity Canada Air absorbed dose rate 2000 m November 2003
Radioactivity Canada Potassium 2000 m November 2003
Radioactivity Canada eThorium 2000 m November 2003
Radioactivity Canada eUranium 2000 m November 2003

Geosoft’s Oasis montaj and Target for ArcGIS users can download data directly into their working projects by adding the GSC DAP server (gdr.agg.nrcan.gc.ca) to their DAP data retrieval tool. For information on how to add a DAP server to the Geosoft DAP tool, please refer to: http://www.geodap.com/dap_howto.htm
