The app includes all maps within the installation package, ensuring users have seamless access without additional downloads or fees. Designed specifically for outdoor enthusiasts and professionals alike, this app is ideal for backcountry navigation where cellular service may be unavailable.

Key features include GPS positioning, track logging, user waypoints, orientation tools, altitude and speed display, distance measurement, and route creation capabilities. Users can search for specific locations, import/export tracks in KML or GPX formats, and benefit from specialized overlays such as DOC open permit hunting boundaries. Built on New Zealand's national map grid, it ensures accurate projections tailored to local geography.

This app stands out with its robust set of navigation functions designed for diverse outdoor activities. It offers precise GPS positioning, allowing users to accurately track their location on detailed topographic maps. Track logging and waypoint management enable users to record journeys and mark important locations, while orientation tools provide compass functionality and display altitude and speed metrics.

Additional functionalities include measuring distances and bearings to points on the map, creating routes for future exploration, and following pre-established paths. The inclusion of various overlays like DOC open permit hunting areas enhances situational awareness. Furthermore, the app supports importing and exporting tracks and waypoints in industry-standard KML and GPX formats, facilitating data sharing across platforms.

A distinctive feature is its use of the NZ national map grid rather than the global WGS84 datum, ensuring unparalleled accuracy in map projections. This attention to detail guarantees that users experience minimal distortion when navigating through challenging terrains.

Map accuracy is crucial for reliable navigation, especially in remote areas. NZ Topo50 Offline - South excels in this domain by providing complete 1:50k offline topographic map coverage using the LINZ NZTopo50 series maps.

The app includes all maps fully with the install, ensuring no missing tiles or need for additional downloads. This seamless integration guarantees that users can pan and zoom across the whole South Island without interruptions.

Unlike many mapping applications that use the global average WGS84 datum, this app is built from the ground up to use the NZ national map grid. This results in perfectly parallel gridlines when the LINZ map is projected, offering unparalleled accuracy tailored specifically for New Zealand's unique geography.

Effective route planning can make a significant difference in outdoor adventures. NZ Topo50 Offline - South offers robust navigation functions including GPS positioning, track logging, user waypoints, and orientation features.

Users can create routes, follow predefined ones, and even search for named places and features on the map. The app displays altitude, speed, distance, and bearing to points on the map, enhancing the precision of any planned route.

Additionally, tracks and waypoints can be imported, exported, and shared in kml or gpx format, making it easy to collaborate with fellow trampers, walkers, bikers, runners, hunters, and search and rescue teams. Overlays such as DOC open permit hunting boundaries and Te Araroa tracks further enrich the route planning experience.
