Modifying map screen

You can modify the map in the main screen by scrolling, zooming, centering and rotating the map.

Scroll

To scroll the map you have to hold a finger on the map. When you move your finger, the map will be moved as well. You can also move the map by making a quick swipe with your finger on the map.

Zoom

You can zoom the map in or out in two ways:

• Zooming in: Tap one finger on the bottom of the map. Or hold two fingers on the map and bring them together.

• Zooming out: Tap one finger on the top of the map. Or hold two fingers on the map and move them away from each other.

At some point it is not possible to zoom in further. If you want to enable additional zoom, you can do this by enabling the setting Menu > More > Settings > Map > Additional zoom in. The drawback is that then map will become grainy when zoomed in far.

Center

By tapping the position marker icon on the bottom left of the main screen, the map will be centered on your current location. An example is shown in the figure below.

A centered map.

If you are moving, the map will stay centered automatically. The map will move automatically with your movement.

The map stays auto centered as long as you do not move the map manually. To zoom in or out while keeping the map centered, tap on the bottom or top of the map. Zooming with two fingers will cancel the automatic centering.

Centering the map on your location only works if you have given Topo GPS access to your location. You can do this in the settings app. Go to Settings > Privacy > Location services > Topo GPS.

If you have centered the map on your location, the position marker icon on the dashboard will be changed to a rotation icon.

If you use a keyboard you can also tap ‘c’ to center the map.

Rotate

You can rotate the map in two ways, automatically and manually.

Automatic rotation

By tapping once on the position marker icon on the bottom left of the screen, the icon turns into a rotation icon as you can see in the figure below. If you tap this rotation icon, the map will be automatically rotated in your direction.

The map is rotated such that the top of the map indicates the direction in which you point your device if your are standing still. If you are moving the top of the map will indicate the direction in which you move. An example is shown in the figure below:

Rotating the map can be useful when you are following a route. Left and right on the map are than also left and right in reality. In addition the position maker will stay centered on the map.

If the map does not point to the right direction if you are standing still, you might need to calibrate the compass of your device. For this, rotate your device three times around a fictional line from the middle of the bottom to the middle of the top of your device. Then rotate your device three times around a fictional that line that goes from the middle of the left to the middle of the right of your device. Then rotate the device three circles with the screen pointing upwards.

If the map is rotated, an north arrow will appear on the top left of the screen. This arrow indicates the direction of the true north on the map. If you press this arrow the rotation will be cancelled.

You can cancel rotation by pressing the position marker button on the dashboard.

If you move the map or zoom with two fingers automatic rotation will be switched off. The current rotation angle will then not longer change and the map will no longer be centered at your current location. To zoom the map in or out while keeping the automatic rotation active, tap on the bottom or top of the map screen.

Manual rotation

If you put two fingers on the screen and make a rotation gesture by moving the two finger clockwise or counter-clockwise, the map will be rotated around the point that lies in between the two fingers. An example of a rotated map is displayed in figure above. You can rotate the map in every desired direction.

If the map is rotated, an north arrow will appear on the top left of the screen. This arrow indicates the direction of the true north on the map. If you press this arrow the rotation will be cancelled.

If you zoom the map or move the map the map stays rotated.

Manual rotation can be cancelled by pressing the north arrow. It is also possible to undo the rotation by manually rotating back to the normal situation.

Long press

If you press long on the map an icon will appear which you can drag to a certain location. If you release it, you can create a waypoint on that location. If you accidentally pressed long on the map, drag the icon to the top of or the bottom of the main screen. The icon will disappear and the waypoint creation screen will not be shown.

If you put a second finger on the map after the waypoint creation icon has appeared, the map ruler will be shown. You can use the map ruler to measure distances and angles.
