RandoCartes — manual

Welcome to RandoCartes. It’s an application for helping you to navigate when out walking or hiking

The application started life on Windows and some of the functionalities described are still only avaiable on that platform. But don’t worry, we are working to bring the Android version to the same state.

Important information concerning the IGN service: the IGN site is being modified. Please use this link to manage your service key.

Getting started

When you run RandoCartes (and as long as you have an internet connection) you will see a map of Nancy in France. This is the default startup location.

Of course, this is probably not the place you want to see on the map. You can use pinch gestures to change the zoom level of the map and swipe gestures to move the position of the map. If you have GPS activated you can press the icon to move the map directly to your current position. If it doesn’t work straight away, wait until the GPS has a fix.

If you want a different map base (the default is OpenStreetMap), press the icon. It will give you a list of map services to choose from and you can select the one you want.

Initially the IGN and ThunderForest services are not available. To use these you must go into the menu (three dots) and choose the ‘Service settings’ (Android) or ‘Services’ (Windows) option. Under the appropriate service you will find instructions for obtaining a key from the provider to use these services.

Icon bar

The horizontal row of icons gives you access to functions that control how the map is displayed.

Map service — This icon allows you to choose the map service to use for displaying maps. When you click here you will see the list available. You can control which services appear here by using the ‘Service settings’ (Android) or ‘Services’ (Windows) menu.

Enable auto-centre — This icon shows that the current position is allowed to be moved as you wish. If you click on it you set the auto-centring mode where your current position will always stay in the centre of the screen. This is useful if you are moving and don’t want to keep shifting the position of the map to see where you are.

Disable auto-centre — This icon shows that the current position will always be kept in the centre of the screen. (You can move it but it will always come back when a new position update is received from the GPS.) If you click on the icon you disable the auto-centring mode and you will be free to move the map as you desire.

Move map to current location — When you press on this button the map will be moved so that your current position is at its centre. If GPS is not active, or not available, no action will be taken.

Hide annotations — This icon indicates that annotations are visible on the map. When you press it, your current position, as well as any tracks currently displayed (Windows only), will be hidden. This allows you to see the details on the map that they may have been hiding.

Show annotations — This icon indicates that annotations are not currently visible on the map. When you press it, your current position and the tracks (Windows only) that were previously hidden, will be redisplayed.


By selecting the menu (three dots) you obtain access to these other functions.

Start tracking — allows you to create a trail by following your movements.

This option is only enabled when the application has access to your GPS position. When you select it, you will be asked to confirm your choice and, after confirmation, the application will start tracking your movements and displaying them as a yellow line on the map. This will continue even if you change to another application or put your device to sleep.

Stop tracking — finish saving your movements and save them as a trail.

This option, which is only available when tracking, will first ask for confirmation that you wish to stop tracking your position. After confirmation you will be asked to provide a name under which to save the trail. You can accept the suggested name or type your own. The yellow line will then be removed from the map and the trail saved. You will then be able to see it under the ‘Trails’ menu option.

Trails — pressing this button takes you to the trails management screen where you can import and export trails as GPX files and display them on the map.
