dist_calc: Calculate 2D and Cumulative Distance Between Coordinates

In bouzidnm/tinker: Miscellaneous Functions for Data Cleaning, Formatting, and Visualization

Description

Appends two columns to a data frame containing Longitude and Latitude coordinates. The first column (Dist) is the incremental change in distance between coordinates. The second column (DistTotal) is the cumulative distance along a 2D transect beginning at 0.

Usage

dist_calc(df, longlat = TRUE)

Arguments

longlat	logical for calculating Great Circle (TRUE) or Euclidean (FALSE) distances. Defaults to TRUE. Great Circle distance is returned in km.
x	data frame containing coordinate data as columns labeled "Longitude" (x) and "Latitude" (y).

Details

Relies on the spDistsN1 function from the package 'sp.'

Examples

df_dist <- dist_calc(df, longlat = TRUE)
