airportdb is a small tool to generate a JSON database of airports with google coordinates and google placeIds.
Two different sources are used as an example:
- one in JSON format shamelessly copied from here
- the Global Airport Database in CSV format
Build the fat-jar with
-$ sbt assembly
and then export your google maps api key and run the jar
-$ export MAPS_API_KEY="XXXXXX"
-$ java -jar target/scala-2.12/airportdb-assembly-0.1.jar [jsonInput | csvInput]
and pick the output json file.
An airport is modelled by the following case class:
case class Airport(
openflightsAirportId: Int,
name: String,
city: String,
country: String,
iataCode: String,
icaoCode: String,
latitude: Double,
longitude: Double,
elevation: Int,
offsetFromUtc: Option[Double],
daylightSavingsTime: String,
timeZoneAsString: String,
localizations: Map[String, Localization],
googlePlaceId: Option[String]
)
where Localization is simply case class Localization(city: String, name: String). The final JSON is a straightforward marshalling of the above.
