  DMTI road segments are generally accurate up to 60cm in most urban areas, and as low as 15m-30m in rural areas. As all CanMap segments have been referenced against digital sources, as well as satellite imagery, their accuracy may vary from the above statement for a number of different reasons, albeit at a very small scale: -Lower-quality satellite imagery -New roads created that do not exist in the most recent satellite imagery -Improper referencing of existing satellite or aerial photography (due to lack of control points).
