Navigate the Network Linked Data Index network.
navigate_nldi(
nldi_feature,
mode = "upstreamMain",
data_source = "flowlines",
distance_km = 10
)Arguments
- nldi_feature
list with names `featureSource` and `featureID` where `featureSource` is derived from the "source" column of the response of get_nldi_sources and the `featureID` is a known identifier from the specified `featureSource`.
- mode
character chosen from ("UM", "UT", DM", "DD"). See examples.
- data_source
character chosen from "source" column of the response of get_nldi_sources or empty string for flowline geometry.
- distance_km
numeric distance in km to stop navigating.
Value
sf data.frame with result
