The Node Menu

The Node menu is used to create, edit, move, link/unlink and delete 'User nodes'.

User nodes are geographical entities of various types, including :-

  • Waypoints: fixed geographic locations, often used as stages along a route

  • Zones: circular regions about a geographic location. May also be associated with waypoints, points and tracks

  • Points: typically indicate static entities (though they can be moved)

  • Tracks: typically used to indicate transient, moving objects (although any type of node can move)

    Below is an example of each user node type ...

    Waypoints are always light blue in colour. Points, zones and tracks each have a 'designation' attribute associated with one of five selectable colours - yellow, grey, blue, green, or red. The designation affects the description of a node within messages.

    Yellow nodes are not annotated. Grey, green, blue and red are each associated with a descriptive keyword which also depends upon whether or not the War-loc mode is selected, as follows :-

  • Grey: "PRIVATE" normally, "STEALTH" in War-loc mode

  • Blue: "SAFE" normally, "FRIENDLY" in War-loc mode

  • Green: "GREEN" normally, "NEUTRAL" in War-loc mode

  • Red: "HAZARD" normally, "HOSTILE" in War-loc mode

    Note that a red bearing/distance vector is always shown from your own node to each HAZARD/HOSTILE node.

    Private Zones

    Of particular importance for location privacy is the ability to create zones with a 'private' designation. Your position is never made publicly visible from within a private zone - regardless of your current Base Tx Resolution setting. You can, optionally, enable transmission of your position to your team only from within a private zone by checking the TxP checkbox (which is shown instead of the Pub box for private zones only).

    It is strongly recommended that you define private zones around geographically sensitive areas such as your home and place of work (school, etc). You might wish to enable team access to your position within, for example, your work private zone.

    Viewers using Google Earth to observe your location data sent to the base server see the location pin stopping near the edge of any private zone that you enter. Similarly, your team will not see your location enter a private zone unless you have specifically allowed it for that zone.

    Managing User Nodes


    Initiates the creation of a new user node at the red 'crosshair' cursor shown at the centre of the screen. Drag the screen to position the cursor where the new node is to be placed, then tap on the cursor to create the node. The type of the node is the same as that of the previous node created (if any) - initially a waypoint.

    Note that this button also shows the Del and Move buttons.

    Prev, Next

    Select a previous or next user node from those currently defined. The order is arbitrary (related to their order of creation).


    Selects 'deletion' mode. Deletes all nodes under the cursor (on tapping the cursor).


    Selects 'move' mode. Tapping the cursor moves the currently selected node to that position.


    Links the currently selected node to the previously selected node or, if already linked, snaps the link.

    Editing User Nodes

    To edit a user node first select it either by using the Prev and Next buttons or simply tap the screen near it. Several edit buttons and boxes (depending upon the type of node) appear, through which the characteristics of this node can be changed.

    A bearing/distance vector (coloured according to node designation) is shown from your own node to the currently selected user node.


    Toggles the user node type between waypoint, zone, point and track.


    Toggles the user node designation/colour between 'none'(yellow), private/stealth(grey), safe/friendly(blue) and hazard/hostile(red).


    Toggles the user node 'dimension' (operating environment) between ground, air, surface, subsurface and space(!). This control is only shown for points and tracks.

    Rad+, Rad-

    Increase or decrease, respectively, the radius of a zone (alone or around a point or track).


    The 'public' checkbox, if selected, marks this node as visible to all other team members; otherwise only you can see it.


    The 'TxP' checkbox, only shown (instead of Pub) for Private Zones, enables transmission of your location to your team only from within this private zone.
