fwa_locate_along(
  blue_line_key,
  downstream_route_measure = 0,
  bbox = NULL,
  properties = NULL,
  transform = NULL,
  epsg = 4326,
  nocache = getOption("fwa.nocache", FALSE)
)

Arguments

blue_line_key	A positive whole number of the stream blue line key.
downstream_route_measure	A positive number of the river metre.
bbox	A vector of four numbers indicating bounding box to limit output features to, e.g. c(minLon, minLat, maxLon, maxLat).
properties	A vector of strings of the column names to include. If NULL (default), all columns are retained.
transform	A character vector with the name of the valid transform function followed by the parameter values (e.g. c("ST_Simplify", 100))
epsg	A positive whole number of the epsg to transform features to.
nocache	A flag specifying whether or not to cache results.
