The Map Menu

The Map menu allows you to adjust your map display scale; centre it on your own position or that of a team member or user node; select its 'mode' (street, satellite, etc); control the labelling of positional markers and the display of trail points. It also offers access to the 'Spot' mode - with which you can 'point' out distant objects to other team members.

In and Out

Zoom in or out, respectively, the scale of your map display. Each step halves or doubles the geographic distance across the screen. The current display scale is shown as a single number in the yellow box between these two buttons (higher numbers are more 'zoomed in').

Own

Brings your own location to the middle of the screen and keeps it there if you move. This obviously requires that your geographic location is known to some degree ... for example, as a coarse position from your network provider or a fine location from your GPS receiver. You can also be simulating your position. This button is particularly useful if your current location is not on the display - if you can see your own node then just tap on or near it to achieve the same effect.

Usr

Locks the screen to the currently selected user node, if any. You can 'select' a user node by touching the screen near to a visible node or via the Prev and Next buttons on the Node menu.

Ref

Locks the screen to the currently selected reference node, if any. The 'reference' node is simply one of your team members that you have 'selected' - either by tapping near their displayed symbol or via a Ref button on the Team List menu.

Note that if there is only one other team member (other than you) then they are automatically selected as your 'reference' node.

Mode

Toggles the map 'mode' between 'ROAD', 'SATELLITE', 'STREETVIEW' and 'TRAFFIC'.

Labs

Toggles the selection of labelling around position markers through the sequence: "All labelling hidden"; "Node UID display enabled"; "Node description display enabled" and "Speed/Heading display enabled". Each adds more to the previously displayed data.

Trail

Toggles the number of 'trail' points to be shown (none,5,10,25,50 or 100). These are the locations saved whenever a team node's navigation data is sent or received. Your own trail points are shown in (fading) red; those of team members are yellow.

Time markers indicate the number of minutes ago that each trail point was reached.

Spot

Selects the 'spot' mode, in which a red line can be displayed projecting from your location along your current compass direction (see image below). Check the 'Spot' checkbox to enable display of your own 'spot line'. This is also visible to all of your team members and is intended as a 'pointer' to a remote object from your own viewing position.

If another team member (preferably some distance from you) also 'spots' the same object then your spot lines will cross at the approximate position of the object. This gives an objective fix on a remote object without requiring your (likely, error-prone) estimation of its distance from your location ("UFO" spotters note!)

Bear in mind that your phone's compass sensor is very susceptible to the presence of external magnetic fields and materials - so be prepared for a little 'variability' in its pointing accuracy!

Spot Range

The near,mid and far radio buttons adjust the length of the red spot line as an indication of the range to the spotted object.
