Title: Anchorage Areas
Status: Completed
Publication Date: 2017-09-20
Abstract:

An anchorage area is a place where boats and ships can safely drop anchor. These areas are created in navigable waterways when ships and vessels require them for safe and responsible navigation. A variety of designations refer to types of anchorage areas or restrictions, or even to alerts of potential dangers within an area. Every boater and captain should be aware of the various types of areas. These data are intended for coastal and ocean planning. Not for navigation.

Purpose:

To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.

Process Steps

Process Step 1

CC ID: 651165
Description:

1. Go to http://www.gpo.gov/fdsys/pkg/CFR-2016-title33-vol1/pdf/CFR-2016-title33-vol1-chapI.pdf, http://www.gpo.gov/fdsys/pkg/CFR-2016-title33-vol2/pdf/CFR-2016-title33-vol2-chapI.pdf & http://www.gpo.gov/fdsys/pkg/CFR-2016-title33-vol3/pdf/CFR-2016-title33-vol3-chapIV.pdf and record all anchorage area info into a spreadsheet including lat/long data

2. Import sheet into ArcGIS, convert to xy coordinates, and export as a point feature class

3. Convert point feature class to polygon by connecting corner coordinates and joining attribute info

NOTE: Areas from the following locations were not included, as they are all inland locations:

Section 110.127 Lake Mohave and Lake Mead, NV and AZ

Section 110.127a Lake Powell, UT-AZ

Section 110.127b Flaming Gorge Lake, WY-UT

Section 110.72c Lake Murray, SC

4. Go to https://encdirect.noaa.gov/ and download the following at full extent:

Approach_Anchor_Berth_area, Approach_Anchor_Berth_point

Approach_Anchorage_Area, Approach_Anchorage_Area_point

Coastal_Anchorage_Area, Coastal_Anchorage_Area_point

General_Anchorage_Area, General_Anchorage_Area_point

Harbour_Anchor_Berth_area, Harbour_Anchor_Berth_point

Harbour_Anchorage_Area, Harbour_Anchorage_Area_point

Berthing_Anchorage_Area

Overview_Anchorage_Area_point

5. Import all of the polygon layers into a single feature class and the point layers into a separate feature class

6. Buffer the point features to 500 feet

7. Compare between the layers, removing duplicates, and compare to NOAA_RNC continuous raster at ArcGIS on seamlessrnc.nauticalcharts.noaa.gov as a guide

8. Union the polygon and point feature classes with the CFR feature class and merge and combine features where overlap occurs, again giving the CFR features the most importance

9. Fill in any missing attributes using RNC info

10. Delete all superfluous fields

11. Check geometry and project data into WGS 1984 Auxiliary Sphere
