General information about OGN data
The better the data quality, the better the representation! This may sound somewhat simplistic, but it is crucial for all applications that depend on this data. A compromise must be found between a “perfect, realistic” and smooth representation. Data can, of course, be optimized, but the question is how many computational resources will be required for this.
In “Glider Viewer,” all position data is calculated using a mathematical logic (Centripetal Catmull-Rom Spline). This ensures that the flight objects do not fly around corners. In other words, the flight objects have a smooth flight path. However, this does not change the fact that if data is missing or faulty, the flight may stop or sometimes display confusing maneuvers.
OGN
The quality of OGN data is good but not very good. There can be interruptions or dropouts. The quality and availability depend on the data provided by OGN. The color coding is as follows:
- Green: Data available (< 5 seconds)
- Orange: Waiting for data (> 5 seconds and < 15 seconds)
- Red: No data available (> 15 seconds)
