MapGazer is a free program for viewing and saving maps and also viewing, editing, and saving GPX data (tracks, routes, waypoints, and areas).

MapGazer is especially useful when the device in use has an unreliable (or no) internet connection, because it uses ‘offline’ maps (maps stored on your computer or tablet). It is fast and simple to use, and allows uncluttered viewing of maps.

Please click on the ‘Using ...’ menu items on the left to see screenshots illustrating the main features; or click on ‘Getting started’ for an overview of the application.

MapGazer features:

  • MapGazer uses tiled maps which can be downloaded from many sources (see Getting maps). You can overlay another map (e.g., geological) with variable transparency (see this animation, and also Using transparency). You can also use downloaded elevation data to add height information to maps.

  • GPX files can be loaded to add tracks, routes, waypoints, and areas; all of these can be edited and then saved back to GPX files – see below for an example of a map with a track and some waypoints.

  • You can easily create images from maps (which can be much larger than screenshots), merge and compress maps, and create subsets of maps (for example, for a mobile phone).

  • The user interface is ‘modeless’; tracks, routes, waypoints, and areas can be edited directly (without first entering a ‘routing mode’, etc.); in particular:
    • tracks can be trimmed to remove unwanted points at the start or end
    • routes can be created, adjusted and detailed by dragging, have waypoints added, and let you measure distances
    • waypoints (points of interest) can be created, adjusted by dragging, and be assigned icons and colours
    • rectangular areas can also be created and adjusted by dragging the edges or corners.

  • You can edit the main properties (name, colour, icon, link URL, etc.) of tracks, routes, waypoints, and areas. Many details and statistics (such as the length, time, elevations, and duration of a recorded track) can be viewed and easily copied to the clipboard.

  • Multiple views (windows) are supported – the map (and any overlay map) displayed in each view can be changed or zoomed (using mouse, keyboard, or touch screen) at will, which allows detailed inspection of different areas. Any GPX data (tracks etc.) will appear in all relevant views.

  • By default an automatic Scale bar shows a indication of distance on the map (you can also measure distances using a Route).

  • The visible map is maximized by the ‘retro’-style menu bar; further, the menu bar and/or title bar can be hidden, or maps can be viewed full-screen; you can also open a satellite view that matches a map view (if an internet connection is available).

Here is an example of a topological map showing a recorded track and associated waypoints (showing some icon colour possibilities):

MapGazer runs on a Windows personal computer (PC, laptop, or tablet, running Windows 7 or later); it also runs on Windows XP and Windows emulators on Mac OS and Linux, but is not fully tested in those environments.

Internally, MapGazer permits the use of any tiled map format; for storage it uses the MGMaps map format (as used by MyTrails and other applications – see Getting Maps).  I’m open to suggestions for other formats to support for storage; ideally one for which pre-packaged offline maps are available.

MapGazer has been written ‘from scratch’, but is inspired by – or uses libraries by – many people, acknowledged here.
