A framework for obtaining and working with airport information from publicly available databases. The typical usecase is to resolve information such as name, country and timezone information from e.g. an IATA code.

Ibistic.Public.OpenAirportData has two main components: providers for downloading airport data from publicly available sources and a memory database to organize and utilize that data.
These providers offer access to Openflights Airport and Country data available from https://openflights.org/data.html.
There are two providers offered; one for downloading airport data and one for downloading country data, since the first specifies countries by name and not by ISO codes. Both providers work by downloading the data over HTTPS from OpenFlights' repository on github.com and caches it to a file specified by the user, to avoid exessive downloads.
The typical use case for downloading airport data combined with country information is as follows:
using Ibistic.Public.OpenAirportData;
using Ibistic.Public.OpenAirportData.OpenFlightsData;
//...
var airportProvider = new OpenFlightsDataAirportProvider("airports.cache", new OpenFlightsDataCountryProvider("countries.cache"));
IEnumerable<Airport> airports = airportProvider.GetAllAirports();If you want to keep all airports in memory and query by Iata code, you may use the class AirportIataCodeDatabase. This is used as follows:
using Ibistic.Public.OpenAirportData;
using Ibistic.Public.OpenAirportData.MemoryDatabase;
using Ibistic.Public.OpenAirportData.OpenFlightsData;
//...
var airportProvider = new OpenFlightsDataAirportProvider("airports.cache", new OpenFlightsDataCountryProvider("countries.cache"));
IEnumerable<Airport> airports = airportProvider.GetAllAirports();
AirportIataCodeDatabase airportCodes = new AirportIataCodeDatabase();
airportCodes.AddOrUpdateAirports(airportProvider.GetAllAirports(), true, true); //Adds airports to the database, clearing out old ones and ignoring those lacking Iata code
string iataCode = "AGP";
if (airportCodes.TryGetAirport(iataCode, out Airport airport)
{
Console.Out.WriteLine($"IATA code {iataCode} is assigned to the airport {airport.Name} in {airport.City} ({airport.CountryAlpha2})
}Note that both the providers and memory database have code for controlling expiry. Please refer to the public properties of the different classes.
