Add River Meters to Blue Line Key — fwa_add_rms_to

Adds distances (rm) and spatial coordinates (geometry) of regularly spaced points along blue line key (blk). All distances which are in meters are from the river mouth.

fwa_add_rms_to_blk(
  x,
  interval = 1000,
  start = 0,
  end = Inf,
  epsg = getOption("fwa.epsg", 3005),
  nocache = getOption("fwa.nocache", FALSE)
)

Arguments

x: A data frame with integer column blk.
interval: A whole numeric of the distance between points.
start: A whole numeric of the start distance.
end: An integer of the end distance.
epsg: A positive whole number of EPSG projection for the coordinates.
nocache: A flag specifying whether or not to cache results.

Value

An sf tibble with the columns of x plus integer column rm and sf column geometry.

Examples

if (FALSE) {
fwa_add_rms_to_blk(data.frame(blk = 356308001))
}
