The 1:50,0000 maps cover a quarter degree of latitude north/south, about 28 km. East/west they cover half a degree of longitude, which in our area is about 36 km.

The maps have been updated in a sequence of numbered "editions", marked in the lower right or upper right corner. The latest edition is usually Edition 2 or Edition 3. It's unusual to find an outdated edition being sold.

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.

* 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.

* Single sided. The maps should have a key of symbols (legend) on the back side. Each map has its own custom legend including any unusual symbols on that map.

* Folded. Maps are sometimes sold folded instead of rolled. The folding will make it harder to use the maps on a map table. If you're going to use the map in the field instead, you'll probably want the creases in different places, and the original creases will make handling the map difficult.

Make sure you're clear you're asking for the 1:50,000 maps. There's a separate series that is 1:250,000 which covers more area but has less detail.
