Title:	Aids to Navigation
Status:	Completed
Publication Date:	2019-05-16
Abstract:	Structures intended to assist a navigator to determine position or safe course, or to warn of dangers or obstructions to navigation. This dataset includes lights, signals, buoys, day beacons, and other aids to navigation. Not for navigation.
Purpose:	To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act.
Supplemental Information:	The native coordinate system for this layer is NAD 1983 (ESPG: 4269). Please note: all MarineCadastre.gov data served by the NOAA Office for Coastal Management and hosted through Esri REST services are in the WGS 1984 Web Mercator Auxiliary Sphere (EPSG: 3857) projection.

Process Steps

Process Step 1

CC ID: 836617

Description:

• Go to https://www.navcen.uscg.gov/?pageName=lightListWeeklyUpdates and download the 10 xml documents • Import xmls in to Excel (Data, Get External Data, From Other Sources, From XML Data Import) and select the "Existing worksheet" option (beginning data import in cell A1) • Remove unnecessary columns or rows and rename column names • Combine the 10 spreadsheets into one, checking that the column names match up • Sort columns latitude and longitude and delete features missing coordinate info • Remove line breaks, fix typos and grammar issues, remove partial sentences where column values have been truncated and standardize attributes where these were easily discernable • Change necessary latitude and longitude values to negative (i.e. for features in the southern and western hemispheres, respectively) • Convert Excel To Table (Conversion Tools, Excel) and load the spreadsheet into ArcMap • Display XY data and export data as a feature class • Perform visual inspection of the features plotted in ArcMap and modify/delete as needed • For district 8, populate the location and structure fields with info from bank, mile, structure up and structure down fields • Delete all superfluous fields • Check geometry and project data into WGS 1984 Auxiliary Sphere
