Meeting Minutes, December 2, 2013
Initial Brainstorming Meeting
Live-Delay Analysis
- GPS per competitor
- wind for advantage line
Outlier detection
- GPS tracks
- Wind
Dropout interpolation
- GPS tracks
- Wind
Connection loss
- GPS Track:
- introduce states "no data" / "no connection"
- has to be based on transmission rates
- no ping available
- introduce states "no data" / "no connection"
- Wind
Data consistency measures
- Start Phase
- correctness of start time on start boat
- stabilize start detection algorithms / heuristic
- Completeness of Leg
- mark tracks & passings
- gps fixes
- wind measurements
- leg type detection
- Completeness of Race
- competitor tracks: gps, mark passings
- mark tracks: validation (compare marks & competitor tracks); recalculation of mark passings
- all competitor or topN competitors
- all marks or future (remaining) marks
- take into account #{common legs} of competitors in aggregate calculation
- Completeness of Regatta
- (all races complete) only in rare cases achievable
- cleansing of races, if possible
- include race states, e.g. DNF, into aggregate calculations, e.g. average speed
- take into account #{common races} of competitors in aggregate calculation
- Robustness of Aggregate Calculations
- on all levels: leg, race, regatta, regatta series
- aggregate calculation can be corrupted by filtered outliers, lost connection
- Quality based on Outliers and/or Dropouts
- GPS
- Wind
- Network Connectivity
- all required channels
Master Data
- Competitors: names
- Sail numbers
- Boat classes: names
- Scoring schemes: score corrections
Data properties to be visualized or accessible
- Sampling frequency for GPS
- Number of active GPS satellites
- Reflect accuracies of measurements somehow on the UI, e.g. tails along GPS tracks
Extra-/Interpolation of GPS tracks
- bridge phase without connection to network or connection to GPS satellites
Extra-/Interpolation for wind
- bridge phases without estimation or measurement
