National Geographic Database (NGD)

Definition

The National Geographic Database (NGD) is a spatial database that contains attributed roads (names and addresses) and administrative boundaries used to delineate geographic entities such as provinces, municipalities, or even Health Regions. It also contains attributed reference layers such as hydrography (lakes, rivers), railways, transmission and pipelines that provide spatial reference for the delineation of administrative boundaries. The NGD is a shared database between Statistics Canada and Elections Canada as both organizations have shared requirements for attributed road network to conduct their respective business and collective maintenance reduces costs.
