### Further Information
## Minutes from Initial Brainstorming Meeting (December 2, 2013)
### 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
* 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
