Topo50 is the official topographic map series used by New Zealand emergency services.
The Topo50 map series provides topographic mapping for the New Zealand mainland and Chatham Islands at 1:50,000 scale.
- Reference links indicate a relevant warning note or important information.
- Map uses symbols to represent features on the ground which include roads, tracks, rivers, lakes, vegetation, fences, buildings, power lines, etc. Symbols are grouped into themes on the legend key (e.g. "roads and tracks", "railways", "relief features"). Note that given it is not possible to represent every feature on the ground, different scale maps show different levels of information. Larger scale maps show more detail and a greater number of features.
- Colour plays an important part in symbols. For example, blue is used for water features, black for cultural features and green for vegetation features.
