Process Trip Data with District Information

Retrieves and processes trip data from the PDS API by adding district information from community metadata. Filters out unrealistic trips longer than 48 hours to remove outliers and prepares data for monthly statistics calculation.

Usage

process_trip_data(pars = NULL, imei_list = NULL)

Arguments

pars

Configuration parameters containing:

• pds$token: API token for PDS access

• pds$secret: API secret for PDS access

imei_list

Vector of IMEI numbers for devices to retrieve trip data for

Value

A processed data frame with:

• district: District name (from community metadata)

• community: Community name

• trip: Trip identifier

• boat: Boat identifier

• landing_date: Date of trip landing

• date_month: First day of landing month

• duration_hrs: Trip duration in hours

Details

The function:

• Calls get_trips() API to retrieve trip data for specified IMEIs

• Converts timestamps to landing dates and monthly periods

• Calculates trip duration in hours from seconds

• Joins with community metadata to add district information

• Filters out unrealistic trips (>48 hours)

• Standardizes column names and structure

• calculate_monthly_trip_stats() for using processed trip data

• get_trips() for the underlying API call

• get_metadata() for community metadata retrieval

Examples

if (FALSE) { # \dontrun{
# Process trip data with parameters and device list
pars <- read_config()
trips_stats <- process_trip_data(
  pars = pars,
  imei_list = imei_list
)

# Check data structure
str(trips_stats)
} # }
