The GSDNR program's National Transportation Network (NTN) project recently released the first ever updates to the National Road Network (NRN) for the Northwest Territories, Prince Edward Island, and the Yukon. These updates can be found on the GeoBase web site, and are available for download free of charge.

These first updates mark a major milestone for the NTN project as well as for the GeoBase initiative. In addition to highlighting the continued cooperation with the provinces and territories that the NTN project has undertaken, these updates underline one of the key benefits of the NRN project, which is the accessibility of the most recent, accurate, and standardized road network data.

More updates to the NRN are forthcoming, with the next set expected to be for the province of Nova Scotia, which should be available in late fall. Subsequent provincial and territorial updates will follow regularly.

In addition, the NTN project is now developing and validating a process that will produce files that contain NRN changes (deltas) for each updated NRN dataset. Users will now have a choice of starting with the latest NRN version or integrating changes (deltas) from their previous NRN version to create the latest version of the NRN dataset.
