GPS track point information extraction.

Description

Allows extracting and generating new information from track points data collected with GPS.

Usage

path_gps(
  filename = NULL,
  layer = "track_points",
  time_zone = "Etc/GMT-0",
  zone_correction = "Etc/GMT+3",
  arq_type = c("shp", "gpx")
)

Arguments

filename

string designating the file .gpx or .shp path in geographic coordinates

layer

string that designates the layer with the trackpoint data when arq_type = "gpx", in case arq_type = "shp" layer is ignored

time_zone

string designating the gps default time zone

zone_correction

string designating the time zone for correction

arq_type

string that designates whether the file is type "shp" or "gpx", "shp" default

Value

returns a data frame with information about time, coordinates, elevation, distance, speed, elevation difference and azimuth (always calculated in relation to the later point)

Examples

path.file.ex <- base::system.file("extdata", "trajeto_teste.shp", package = "gps.track")
df.gps <-
path_gps(
  filename = path.file.ex,
  time_zone = "Etc/GMT-0",
  zone_correction = "Etc/GMT+3",
  arq_type = "shp"
)
