In-Depth Information
For each airport the number of arrivals and departures was computed,
along with average arrival and departure delays. Since location is central to
understanding routesandpatterns, latitudeandlongitudewasalsoincluded
for each airport:
Airport,Arrivals,Departures,Flights,Avg Arrival Delay

Departure Delay (min),Airport

ATL,31894,31887,63781,15,14,Hartsfield-Jackson Atlanta

Visualizing Route Segments
For a data set of this scale, Gephi is a good option for rapid analysis. Use
GDF again to import your data. Copy the node data into a new file, and
insert the
nodedef>
tag, labeling the airport code column as
name
. Next,
assign a type to each column—
VARCHAR
for text and
DOUBLE
or
FLOAT
for numbers. Append the link data to the node data and repeat a similar
process, beginning with an
edgedef>
tag. Change the name of the
Flights
column to
weight
so that Gephi will recognize it, and save it as
usflightdata-dec-2013.gdf
.
