Ontario NRN dataset with Street Names, Place Names and Address Ranges
August 31, 2009
On behalf of the Canadian Council on Geomatics (CCOG), Natural Resources Canada (NRCan) is pleased to announce the release of the third province wide update to the Ontario portion of the National Road Network (NRN).
The release files were produced by Land Information Ontario (LIO) based on a maintenance agreement between NRCan, Statistics Canada and Ontario Ministry of Natural Resources - Land Information Ontario with funding support from GeoConnections. This GeoBase NRN release is the third province wide update for this dataset and now includes Street Names, Place Names and Address Ranges as well as coverage of the provincial Resource / Recreation access roads.
LIO maintains a provincial road dataset called the Ontario Road Network (ORN) which is comprised of more than 234,000 kms of roads with a positional accuracy of 10 metres or less and from which the NRN information is extracted. The ORN is road dataset containing attribute information including street names, street addresses, road classification, road surface type, direction of flow and speed limits. The ORN is considered the authoritative source of roads data for the Ontario Public Service under the Government Information Technology Standard, GO-ITS 29.
LIO has invested heavily in building business and technical models to efficiently maintain the Ontario Road Network data. This business model brings together data from the three government bodies with a legislative responsibility for roads in the province. These road authorities are: Municipalities across Ontario, the Ministry of Transportation, the Ministry of Natural Resources and other road authorities. Users can access the ORN dataset by contacting LIO at lio@ontario.ca.
Data Change Management (DCM) files between 2008-09 and 2009-08 releases are also provided for this dataset.
