In wolfeclw/circleclust: Spatiotemporal Clustering for Personal Location Data

Calculate speed and azimuth of series of latitude and longitude coordinates

Description

move() calculates the speed and azimuth (bearing) of consecutive coordinates.

Usage

move(df, dt_field = NULL, jitter_coords = FALSE)

Arguments

df	a data frame containing latitude (lat), longitude (lon), and a datetime.
dt_field	character; name of datetime field.
jitter_coords	logical; if TRUE, coordinates are jittered by a negligible amount (~1 cm). Jittering is recommended if the input data frame contains sequentially duplicated coordinates. Eliminating repeated coordinates is necessary to optimize the circleclust() algorithm.

Value

a data frame with columns for speed (m/s) and azimuth (degrees).

Examples

## Not run: 

move_move(df, dt_field = "Date_Time")

## End(Not run)
