This dataset comes from the links data in the National Waterways Network. It has been edited for by FMRI in the area of coastal Florida, in order to align better with the fl_channels dataset, for use in the FMSAS. No edits were made outside the area of coastal Florida. The original dataset covers the entire United States, but the version posted in the MRGIS SDE database was clipped to Florida and the Gulf of Mexico area in order to be stored.
These data are for informational purposes only, not for navigation.
Links in the waterway network represent actual shipping lanes or serve as representative paths in open water where no defined shipping lanes exist. Nodes may represent physical entities such as river confluences, ports/facilities, and intermodal terminals, US Army Corps of Engineers (USACE nodes), or may be inserted for analytical purposes. Approximately 180 USACE ports are geo-coded in the node database.
Positional accuracy has not been verified by FMRI. The positions of the data were adjusted to align with the FMRI.channels_fl_arc_RED dataset within the Florida nearshore areas.
