# dump1090 aircraft database
|
|
|
|
The dump1090 webmap uses a static database of json files to provide aircraft
|
|
information.
|
|
|
|
This directory has some tools to turn a CSV file with aircraft data into
|
|
the json format that the dump1090 map expects.
|
|
|
|
## Data sources
|
|
|
|
The default data comes from a combination of:
|
|
|
|
* some historical data kindly provided by VRS (unfortunately no longer
|
|
updated) - this data is in vrs.csv.xz; and
|
|
* a data export provided by FlightAware that is updated periodically -
|
|
this data is in flightaware-*.csv.xz
|
|
|
|
The VRS data was extracted by:
|
|
|
|
```sh
|
|
$ wget http://www.virtualradarserver.co.uk/Files/BasicAircraftLookup.sqb.gz
|
|
$ gunzip BasicAircraftLookup.sqb.gz
|
|
$ tools/vrs-to-csv.py BasicAircraftLookup.sqb >tools/vrs.csv
|
|
```
|
|
|
|
The FlightAware data is a subset of the registry information that FlightAware
|
|
uses internally. It contains only the data that FlightAware can redistribute
|
|
to the public; some data sources that FlightAware uses do not allow this and
|
|
are excluded from the export.
|
|
|
|
## Regenerating the json database
|
|
|
|
To regenerate the json database from these input files:
|
|
|
|
```sh
|
|
$ rm ../../public_html/*.json
|
|
$ xzcat vrs.csv.xz | nodejs ./filter-regs.js >vrs-pruned.csv
|
|
$ xzcat flightaware-20180720.csv.xz | nodejs ./filter-regs.js >fa-pruned.csv
|
|
$ ./csv-to-json.py vrs-filtered.csv fa-filtered.csv ../public_html/db
|
|
```
|
|
|
|
Additional CSV files can be given to `csv-to-json.py` if desired.
|
|
|
|
The contents of public_html/db should be installed where the webmap can find
|
|
them; the Debian packaging puts these in
|
|
/usr/share/dump1090-mutability/html/db
|
|
|
|
The CSV format is very simple. The first line must be a header line that names
|
|
the columns. These columns are understood:
|
|
|
|
* icao24: the 6-digit hex address of the aircraft
|
|
* r: the registration / tail number of the aircraft
|
|
* t: the ICAO aircraft type of the aircraft, e.g. B773
|
|
|
|
Any other columns are put into the json DB under the name you give them, but
|
|
the standard map code won't do anything special with them. You can pick these
|
|
columns up in the PlaneObject constructor (see planeObject.js where it calls
|
|
getAircraftData()) for later use.
