For a few locations, especially national parks and the adjacent areas on the same map, a new edition has been created where the map elevations have been converted to metric. These are often Edition 4. Unfortunately when redrawing the contour lines, they have been computer interpolated, rather than replotted from the original (or new) aerial photographs. As a result there is less detail when examining the shape of the land. These maps have also been converted to WGS 84 (a good thing). In total, having the pre-metric earlier edition, if you can find it, would probably be better. | For a few locations, especially national parks and the adjacent areas on the same map, a new edition has been created where the map elevations have been converted to metric.

* Registration issues. We've found some maps where one of the coloured inks is shifted to a different position relative to the other inks. As a result features of that colour are shown in the wrong position. Check the edges (neatlines) of the map where colours of features that would extend off the map, such as forests, rivers, and roads, should all reach to but not cross the map borders. | * Registration issues.
