(GSA file: bal_mob_waterway.shp) Geospatial_Data_Presentation_Form: vector digital data Publication_Information: Publication_Place: Tuscaloosa, Alabama Publisher: Geological Survey of Alabama Description: Abstract: Taken from the National Waterway Network, a comprehensive network database of the nation's navigable waterways, the GSA subset navigable waterways which are within Baldwin and Mobile Counties, Alabama. USACE: The nominal scale of the data set varies with the source material. The majority of the information is at 1:100,000 with larger scales used in harbor/bay/port areas and smaller scales used in open waters. Purpose: USACE: The National Waterway Network is a geographic database of navigable waterways in and around the United States, for analytical studies of waterway performance, for compiling commodity flow statistics, and for mapping purposes. This dataset was compiled by the GIS program of the Geological Survey of Alabama in support of the "Comprehensive GIS Inventory in Coastal Alabama" as funded by the National Oceanic and Atmospheric Administration(NOAA) through the Coastal Impact Assistance Program (CIAP). Supplemental_Information: USACE: 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. This shapefile was clipped from U.S. Army Corps of Engineers Navagation Data Center(NDC) waterway.shp. https://usace.contentdm.oclc.org/digital/collection/p16021coll2/id/2880 Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1994 Ending_Date: 2018 Currentness_Reference: Publication Date Status: Progress: Complete Maintenance_and_Update_Frequency: Continually Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -88.888755 East_Bounding_Coordinate: -87.124088 North_Bounding_Coordinate: 31.350518 South_Bounding_Coordinate: 27.792452 Keywords: Theme: Theme_Keyword_Thesaurus: none Theme_Keyword: network Theme_Keyword: transportation Theme_Keyword: waterway Place: Place_Keyword_Thesaurus: none Place_Keyword: United States Place_Keyword: Southeast Place_Keyword: Alabama Place_Keyword: Baldwin County Place_Keyword: Mobile County Access_Constraints: None Use_Constraints: Any hardcopies utilizing these data sets shall clearly indicate their source. If the user has modified the data in any way they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent these data sets, nor to imply that changes they made were approved by Geological Survey of Alabama (GSA). The GSA should be acknowledged as the originator of the data. This data set is to be used as a primary reference source. This is public information and may be interpreted by organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application. Federal, State, or local regulatory bodies are not to reassign to the originators any authority for the decisions they make. Photographic or digital enlargement of these maps to scales greater than that at which they were originally delineated can cause misrepresentation of the data. If enlarged, the maps will not include the fine detail that would be appropriate for mapping at the large scale. Digital data files are periodically updated. Files are dated, and users are responsible for obtaining the latest version of the data. Boundaries of polygons extending into the water (ocean or Great Lakes) should be considered arbitrary.

Additional agencies with input into network development include Volpe National Transportation Systems Center, Maritime Administration, Military Traffic Management Command, Tennessee Valley Authority, U.S. Environmental Protection Agency, and the Federal Railroad Administration. This data was compiled by the Geological Survey of Alabama using data obtained from the U.S. Army Corps of Engineers Institute for Water Resources Navigation Data Center NDC Publications and U.S. Waterway Network. Native_Data_Set_Environment: Microsoft Windows 7 Professional (Service Pack 1); ESRI ArcCatalog 10.6.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Attribute accuracy is tested by manual comparison of the source with hard copy printouts and/or symbolized display of digital line graphs on an interactive computer graphic system; selected attributes that cannot be visually verified on plots or on screen, are interactively queried and verified on screen. The attribute data within this metadata may be more inclusive than the provided theme attributes. Logical_Consistency_Report: No tests for logical consistency were performed on this data set. Completeness_Report: Files are continually updated Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The "shape source" field in the link database, and the "node source" field in the node database indicate the data sources used to derive link and node placements. The accuracy of each network element is correlated to the data source used to derive that element. For example, links and nodes derived from 1:100,000 scale DLGs are more accurate than links and nodes derived from 1:500,000 scale NOAA Navigational Charts. Links with unknown/missing sources are usually schematic representations of USACE links. Off-Shore: NOAA Charts vary in scale. Larger scale charts were used in harbor/port areas, while smaller scale charts were used in open water. For channels, sea lanes, and Intracoastal Waterways, shape points were placed as needed to ensure that link segments fall within waterway boundaries. Inland: Links digitized from 1:100,000 DLG files, or large scale NOAA charts are the most accurate representations. Shape points were placed as needed to ensure that link segments fall between waterway shorelines. Links derived from Corps milepoints have shape points approximately one mile apart. The Corps milepoints were mainly derived from 1:24,000 and 1:100,000 scale maps. Therefore, the shape points derived from Corps milepoints are often as accurate as shape points derived from 1:100,000 DLG files. However, line segments connecting the shape points may not accurately represent the curvature of the waterway.

A specialized program was written to merge the two networks. In general, Vanderbilt node locations were accepted as authoritative when both data sets had the same elements. This meant moving an Oak Ridge link incident to that node. If the link was classified geographically ocean or Great Lakes, and a Vanderbilt link or chain existed with the same ID and endpoints, the Oak Ridge link was discarded, after transfer of Oak Ridge attributes. If the Oak Ridge link was within 2 km of the new end nodes' location: and 1) if a duplicate Vanderbilt link existed with a higher source code, it replace the Oak Ridge link, or 2) the Oak Ridge link was moved by a logistic adjustment to the new location. (This causes modest disruption to the preponderance of the shape, yet assured that the angle of approach to the displaced end node location was preserved.) If the link was functionally classed "deep draft" and a duplicate Vanderbilt link had an authoritative source code, the Oak Ridge link was replaced. Otherwise an additional shape point was added at the end to snap to the new node location without disrupting the original link shape. If the link had a Vanderbilt duplicate with the same ID, the Oak Ridge link was so flagged to be manually resolved. The composite network was then cleaned manually, resolving all cases of still remaining duplicate links and deciding case-by-case how to smooth or otherwise accommodate a highly displaced Oak Ridge shape into the Vanderbilt digitized node location, using TIGER shorelines as a background.
