What do the TinyGPS++ output parameters mean?
As you can see when you look at the source code of the FullExample.ino that is part of the TinyGPS++ library, the values you marked are:


Course Speed Card*: The current speed (in km/h), course (in degrees) and cardinal course (which is the course translated to a cardinal direction on a compass, i.e. N,S,E,W, NE, NNW, etc.) of the GPS receiver (i.e. you).
Distance Course Card**: The distance (in km) and course and cardinal course to some location or waypoint (London in this example).


After the information you added in your edit, this means the following:


0.00 is your current course over ground (i.e. due North)
0.06 is current current speed over ground (i.e. as good as stationary)
N is your current cardinal course
2365 is the distance to London (km)
294.06 is the bearing to London from your location
WNW is the cardinal bearing to London


* this is also known as SOG (Speed Over Ground) and COG (Course Over Ground, which is used in (aero)nautical navigation) or Bearing.

** this is also known as DTG and CTS (Distance to Go and Course to Steer) when navigating to a GPS waypoint.
