data:

• plane routes: origin, destination airports (lat, lng) - only direct flights
• data: timezone changes on route (origin and destination timezones, airport identification data (name, airport code)

data munging steps:

• add field names to both csvs from source
• initialize your folder, initialize package.json (npm init)
• set up node script with required modules
  • fs (included, 'file system') var fs = require('fs')
  • path (included, utility functions for creating paths) (path.join(__dirname, 'path/to/file'))
  • arc (not included, https://github.com/springmeyer/arc.js/, npm install --save arc)
  • csv-parse (not included, http://csv.adaltas.com/parse/)
• write some tests - tape tutorial
  • file(s) you need to read exist
• read in airport file
• transform it into an object

var airports = {
  SFO: {
    coordinates: [lng, lat],
    timezone: UTC-8
  },
  DCA : {...}
};

• read in route file
• create geojson (FeatureCollection of LineStrings)
  • iterate through the routes file
  • use arc.js to generate the linestrings into geojson
  • populate each linestring's properties with the info you need
• write geojson to a new file (fs.writeFile())

fs.readFile('file1', function(err, data){
  fs.readFile('file2', function( err2, data2){
    // now you have access to both files' data
  })
})
