Waypoint visualization

Dash applies the following logic to eventually display the waypoints (as a sequence of lines connecting such points) associated to a running mission on the map:

  • The logic is triggered when the Started mission <name> important event is received, where the <name> is what is captured in the mission script as follows depending on the language:

    • For an XML script, the mission name is determined by the Id attribute;
    • For a TethysL script, the mission name is as indicated for the mission construct.

    Not all mission scripts have their name equal to the simple name of the file.

  • The <name> indicated in such Started mission event MUST match the simple name (i.e., no path, no extension) of the mission file itself as exposed in the preceding load or run mission event.

    For example, if the started mission event is:

    Started mission sci2

    then, Dash will recognize the preceding "load" command:

    got command load ./Missions/Science/sci2.xml
  • Then, Dash will gather the waypoints from:

    • The arguments in the corresponding mission file that refer to "latitude" or "longitude" (see below).

    • All immediately preceding set commands in the event flow (with respect to the Started mission event) overriding any such arguments.

  • Extraction of latitude/longitude positions to collect the waypoints is ONLY based on:

    • Any defined arguments in the mission with the following names: Lat, Lon, Latitude, or Longitude, as well as those same names with a numeric suffix, e.g., Lat1, Longitude7.

      Dash will pair such names, e.g., Lat3 and Lon3, with the assumption that they define specific locations.

    • Any "set" commands in the event flow that look like the following (using Lat3 as an example):

      got command set <mission-name>.Lat3 <val> degree

For a displayed set of waypoints, clicking or tapping on any of the dashed lines will open a popup containing the following:

  • Last started mission event
  • Vehicle position at time of the started mission event
  • All collected (non-NaN) waypoints
  • Hovering the mouse on a line with coordinates will highlight the corresponding position on the map
  • A "center at" button to center the map at the given position

  • A button 'More details' to open one other popup with further details about the relevant mission events:
