engr_survey2 | R Documentation |
Takes engineering survey points in various units (foot, US survey foot, meters, or kilometers) and calculates the horizontal length in various units (foot, US survey foot, US survey mile, mile, meters, or kilometers).
engr_survey2(
station1,
station2,
station_distance = 100,
units1 = c("foot", "survey_ft", "meters", "kilometers"),
units2 = c("foot", "survey_ft", "survey_mile", "mile", "meters", "kilometers")
)
