Get the stations' data matching the trajectory records

Description

This function takes a trajectory's first point beyond the limit (over the sea) and project its latitude to an straight line made by the corresponding metereological stations

Usage

crossdata(traj.intersections, stations.df, tolerance.sec, timezone,
  searchTranslation)

Arguments

`traj.intersections`	A list made of a character vector and a list. The character vector is the path to each trajectory file while the list contains the first row in the trajectory file which lies over the sea
`stations.df`	A data.frame of metereological station data. It must have at least 4 columns: name, longitude, latitude, and file c("name", "lon", "lat", "file")
`tolerance.sec`	A numeric. A tolerance used when comparing dates
`timezone`	A character. The time zone. i.e. "GMT"
`searchTranslation`	A numeric. The number of seconds for searching metereological station data
