read_so6: Read SO6 file

In euctrl-pru/trrrj: Flight trajectories analysis

Read SO6 file

Description

The SO6 file has variables of two types:

• Segment-specific data (latitude/longitude, time/data information, ...)

• Flight meta data (flight id, callsign, aircraft type, ...)

They are marked S or F respectively in the table below.

Name	Description	Type	Kind
segment_id	segment Id	char	S
adep	Departing aerodrome (ICAO) ID	char	F
ades	Destination aerodrome (ICAO) ID	char	S
aircraft_type	ICAO aircraft type	char	S
segment_hhmm_begin	Segment's begin timestamp (hhmmss)	char	S
segment_hhmm_end	Segment's end timestamp (hhmmss)	char	S
segment_fl_begin	Segment's begin flight level	int	S
segment_fl_end	Segment's end flight level	int	S
status	Segment's status (0=climb, 1=descent, 2=cruise)	factor	S
callsign	Flight call sign	char	F
segment_date_begin	Segment's begin date (YYMMDD)	char	S
segment_date_end	Segment's end date (YYMMDD)	char	S
segment_latitude_begin	Segment's begin latitude (Min decimal)	char	S
segment_longitude_begin	Segment's begin longitude (Min decimal)	char	S
segment_latitude_end	Segment's end latitude (Min decimal)	char	S
segment_longitude_end	Segment's end longitude (Min decimal)	char	S
flight_id	Flight ID	int	F
sequence	Segment's sequence	int	S
segment_length	Segment's length	double	S
segment_parity	Segment's parity	int	S
segment_timestamp_begin	Segment's begin timestamp	datetime	S
segment_timestamp_end	Segment's end timestamp	datetime	S
point_id_begin	Segment's begin point ID	char	S
point_id_end	Segment's end point ID	char	S

Usage

read_so6(filename, delim = " ")

Arguments

filename	the file containing SO6 trajectories
delim	the field delimiter (default: " " [blank])

Value

a data frame where date and time are combined in a single datetime and longitude and latitude are in decimal degrees.
