Contours

The Contour data class consists of linear segments that connect contiguous points of the same elevation that are compiled and used to describe terrain relief. Includes: contour land, contour land approximate, contour land auxiliary/interpolated, contour land depression. In southern Ontario the contour interval is 5 meters. In the near north the contour interval is 10 meters. In the Far North the contour interval depends on the information source. Data is collected on an irregular basis therefore the time period 'end date' may be more recent than indicated above. As individual errors are identified, they will be corrected. Larger updates to the contour layer will not occur until a better elevation source is available.
