GENERAL METHODS OF ENC/CHART EVALUATION

Provide a brief explanation of methods used to evaluate the chart.

For example:

• The ENC Viewer was used to compare charted shoreline to satellite imagery. Comparisons were made over the entire area covered by the ENC.

• Inspection of the ENC was made by boat in the following areas: (describe)

If depths were recorded, please note the echo sounder and positioning equipment that was used.

• Inspection of the ENC was made by automobile in the following areas: (describe)

3. Critical Issues

List those “on the water” issues that you consider hazards to marine navigation. In general, these issues have the potential to cause groundings or are otherwise hazardous to marine navigation. If none are identified, simply state, “No critical issues were discovered”. Negative reporting of critical issues is important.

Examples of Critical Issues:

• Water depths that are shallower than charted.

• Sunken features such as wrecks, rocks, or obstructions that might cause groundings.

• Any feature that is charted as “Visible” but was not seen upon inspection. For example, a charted visible wreck is no longer visible—a charted pile is no longer visible.

• Charted islands that are no longer visible.

For each critical issue Provide:

• Currently Charted Feature: (For example, “Visible Wreck” or “10 foot depth”)

• Latitude/Longitude: DDD/MM/SS (Decimal seconds (SS.SS) if determined by GPS)

• Method of Investigation: Provide date/time of investigation if conducted on the water, name of person in charge, type of vessel, type of positioning system and depth sounder used.

• Description: Describe the nature of the issue. For example, “the chart shows 12 feet depth--we found 3 foot depths in the area.” or…”The chart shows a visible wreck while none was observed when in the area.” Or “There is a charted island, however, it is now a submerged area at all stages of tide.”

• Attach any supporting documentation, such as a chartlet.

4. SHORELINE AND FEATURES

Use NOAA’s ENC Viewer to examine the charted shoreline overlaid on satellite imagery. Note any major changes in the natural and manmade shoreline. Include screen shots of major discrepancies. For manmade features such as piers and jetties, focus on areas where there are numerous features, rather than individual ones.

To determine if something is significant, use the rule “1 millimeter at the scale of the chart” for guidance. In other words, if the chart is a 1:10,000 scale, then a feature that extend 10 meters (or approximately 33 feet) offshore would be significant. At a 1:20,000 scale chart, a feature that extends 20 meters (or approximately 66 feet) offshore would be significant.

Below is a list of other onshore features that can be inspected using the RNC Viewer.

Airports	Ferries	Piers and Docks
Overhead Cables*	Groins	Platforms
Coast Guard Stations	Jetties or Breakwaters	Pipelines
Bridges	Landmarks	Ramps
Dams	Logbooms	Radio Broadcasting Stations
Dikes and Levees	Marine Construction	Rocks
Docks and Piers	Marine Railways	Ruins
Dolphins	Obstructions	Sewer Outlets

*If overhead cables are found that are not charted, please attempt to locate any information in the area as to who owns the cable. If an uncharted submerged cable is located from a sign on the shore, please capture the information onthe sign so Coast Survey can reach out for more information if needed.

5. LANDMARKS

Using the ENC Viewer with imagery, inspect all charted landmarks. Observe if all landmarks are visible on the satellite imagery and fall within the charted landmark circle. If a landmark is not visible on the imagery—a field trip to the landmark may be desirable in order to determine if it still exists. If you are in a boat on the water, then make note if the landmark is visible. A landmark will rarely be deleted based on information obtained only from the imagery. The deletion of the landmark can be confirmed by field observation—either on the water, or by visiting the landmark location.

State that you have examined all landmarks on the chart and make note which landmarks were not confirmed. Provide details for those landmarks that are recommended for deletion.

6. FIELD /ON THE WATER CHART INSPECTION

Field inspection from (on the water of from shore) can provide valuable information regarding the accuracy of the chart. Safety of the vessel/vehicle and crew must be the principle concern when performing chart inspection activities on the water. In general, submerged features-- such as submerged wrecks and obstructions-- will not be deleted from the chart based on a chart inspection survey. Therefore, it is best to stay clear of these types of submerged hazardous features. Types of features that may be addressed on the water:

1. Those issues that have been identified through the ENC Viewer. For example, make observations regarding a new jetty or cluster of piers. Identify public boat ramps that are not charted. Where possible, obtain a GPS position on or near the feature.

2. Confirm that charted islands are now submerged.

3. Identify charted visible wrecks that are now submerged and no longer visible.

4. If you have the capability to conduct depth surveys—identify areas where the chart may be in error. Depth information regarding “Shoaling Reported” notes may be valuable. Transducer depth and tide corrections should be applied to survey depths when possible.

5. Identify features, such as bridges, that are charted “under construction.” If construction on these features appears to be completed, please make a note of this. In regards to vertical and horizontal bridge clearances, do not make physical measurements on bridges. NOAA obtains that information through the USCG and bridge builders.

When possible, insert screenshots of charts in the report to help illustrate the issue.

7. Coast Pilot

View or download the United States Coast Pilot® and search for the section associated with the chart you are inspecting. There may be several paragraphs--sometimes an entire page-- describing the chart. Review the information and identify areas where information is not accurate and changes should be made. Include recommended changes in this section.

Be sure to include the Coast Pilot Number, edition number, affected pages, and paragraph numbers. If everything in the Coast Pilot is accurate, state that the Coast Pilot has been reviewed and no issues were discovered.

8. Miscellaneous

Include any other information or statements regarding accuracy of the chart.

Appendix: Using the ENC Viewer for Chart Inspection

1. Access the ENC Viewer through the Coast Survey home page at https://nauticalcharts.noaa.gov/enconline/enconline.html
