Calculate geodesic distance on longitude, latitude input vectors. The unit of distance is metres.
track_distance(x, y)longitude
latitude
numeric vector of distances between sequential pairs of x, y in metres, see Details
By convention the first value is set to NA missing value, because the
distance applies to each sequential pair of locations.
To use this on multiple track ids, use a grouped data frame with tidyverse
code like data %>% group_by(id) %>% mutate(distance = track_distance(lon, lat))
track_distance(trips0$x, trips0$y)[1:10]
#> [1] NA 129434.87 34631.59 120575.29 30560.42 97593.10 57005.17
#> [8] 108811.27 130587.65 86066.46
