The hexagon grid and the exact figures are our own, so we can recognise our data when we see it.
What is in the files
One day is a single file. More than one day is a ZIP with one file per day and a README.txt that carries the credit. Each day is the UTC day the flights were on.
CSV columns
| Column | Meaning |
|---|---|
date | The UTC day the flights were on. |
cell | The hexagon's id on the map's grid, the same every day. |
lat, lon | The centre of the hexagon, in degrees. |
good | Distinct aircraft whose accuracy (NACp) stayed above 7. |
bad | Distinct aircraft that reported NACp 7 or lower at least once. |
percent | Share affected: 100 × bad ÷ (good + bad). |
colour | The map's colour: green, yellow, red, purple. |
JSON is each day as the API returns it, with every hexagon's outline and the altitude bands: see the hexagon fields. It is about four times the size.
Low reported accuracy is not confirmed jamming and does not identify a source: read the limitations before drawing conclusions. Aircraft data comes from adsb.lol, shared under the Open Database License (ODbL).
