Topo Map 50 Twizel BZ15

• The Topo50 map series use the New Zealand Geodetic Datum 2000 (NZGD2000) – the coordinates of longitude and latitude - and the New Zealand Transverse Mercator 2000 (NZTM2000) projection - this allows the curved surface of the Earth to be shown on a flat sheet of paper.
• Legend key:

-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.
