Maps n Trax

Maps n Trax is an offline map viewer and track recorder. Its primary distinguishing feature is the ability to import and display maps sourced from common image file types such as PNG or JPEG. It can utilise calibration information within some georeferenced image formats such as GeoTIFF. Therefore it is ideal for use with your own topographic or specialised maps scanned from paper or sourced from your local mapping authority. Maps n Trax can also apply navigation features to your own maps, including current location, waypoints and tracks. Tracks can be created by automatic recording, manually or by importing from other sources.

(.ozf2 & .ozfx3 files are NOT supported. See the user guide for more information about these files.)

Imported maps are displayed overlaid on top of the standard iOS world map when the internet is available. A variety of background maps are available to choose from including the iOS standard maps, or you can configure other online maps such as OpenStreetMaps.

With Maps n Trax you can view your own maps on your own iPhone instead of just generic online maps or a limited selection of maps chosen by somebody else. This makes it ideal for specialist maps with details that are not available on other mapping applications, such as highly detailed topographic maps obtained from your government mapping authority or specialised maps you produce with GIS tools. Your imported maps can also be viewed while offline with no internet access, making it ideal for a wide range of outdoor pursuits in remote locations including bushwalking, hiking, trekking, camping, cycling, touring, field work, etc.

Some navigation features are also included, such as showing your current location on the map and keeping your current location centred on screen as well as recording and display of waypoints and tracks. Waypoints and tracks can be imported and exported as GPX or KML files. Multiple tracks can be displayed on the maps simultaneously and tracks with named waypoints can be searched like a directory or gazetter.

WARNING

Before purchasing Maps n Trax be sure that you understand how to prepare your map images for use with Maps n Trax. Please read the User Guide carefully to understand how to prepare map image files for Maps n Trax before purchasing to be sure that it is suited to your needs and abilities. In particular pay careful attention to the section on Preparing Maps as the process to prepare a plain image file for use as a location-calibrated and mobile-optimised map image is non-trivial.

Maps can be imported without calibrating, warping or tiling and Maps n Trax will warp, tile and calibrate the image during import when possible. Maps can also be calibrated (or re-calibrated) manually within Maps n Trax after import if desired. However, preparing maps on the desktop before import is much quicker and more accurate.

IMPORTANT NOTES

• Maps n Trax works with the Spherical Mercator projection and will warp (reproject) other maps into this projection where possible during import. Maps in other projections will be less accurate for location or navigation purposes if not warped. It is recommended to warp maps into Spherical Mercator projection on the desktop before import to Maps n Trax (see user guide).
• Background maps are not available when the internet is not accessible. For offline use you must supply your own maps.
• Maps n Trax is primarily a map viewer, not a navigation tool. The map accuracy, locations accuracy and navigation features should not be depended upon for situations in which inaccuracies or errors could cause danger, commercial loss or any other problems.
• Do not use Maps n Trax while operating a vehicle on land, on water, in the air, underground, underwater, in space or anywhere else.
• Continued use of the GPS running in the background can dramatically reduce battery life on the iPhone or iPad.
