Chart

This page allows you to view charts of your harbor.

OnlineMooring supports two different mapping products from Google to display the charts:  Google Maps and Google Earth.  Both products are free.  Google Maps is the simpler, easier, product, and we try to display charts using Google Maps whenever possible  You may decide to view the maps in Google Earth to obtain more capabilities.

Note:  OnlineMooring works best with Google Earth version 5.0 or above.  In Version 4.x, you cannot click on a berth to get additional information, and the graphics used to display the moorings is not as good.

Options Tab

The option tab allows you to control what appears on the mooring chart

DIsplay Layer - This drop-down list allows you to specify what type of information you'd like to see on the chart.  The options will vary based on what you are authorized to see, and what information is available for your harbor.  If you are using Google Maps, you can view only one of these layers at a time.  If you are using Google Earth, you can potentially view them all.

• Berths - This lets you see the location of all berths for this permit agency
• Selected Berths - When you perform an application search or berth search and click the Chart link below the search results, OnlineMooring creates a layer that only includes the items that appeared in your search results.
• My Berths - This lets you see the location of your own berths.
• Swing Areas- This shows you the areas that boats may occupy, based on the information on file:
  • For single-point moorings.  the swing area appears as a circle.  The radius of the circle is calculated by adding the chain length(s), pennant length, and the vessel assigned to the mooring.   Then the radius is adjusted downward (using the pythagorean theorem) based on the depth of the water, so the deeper the water the shorter the swing area gets.
    • If no vessel is currently assigned to the mooring, we instead use the maximum allowed vessel length entered for the mooring.  If no maximum vessel length has been entered either, then we don't use any vessel info in the swing radius calculation.
    • If no tackle length information is entered, we don't use any tackle info in the swing radius calculation.
  • For double-point moorings, the swing area appears as a rectangle.  The size of the rectangle will be based on the length and beam of the vessel, and will appear centered between the two moorings. 
    • If no vessel size information is available, no swing area will appear.
• MInimum Scope - This will show swing areas around moorings, using a calculated length for the mooring tackle instead of any actual mooring tackle length that has been entered.  The mooring tackle length is calculated by multiplying the water depth by the minimum scope number that you enter here.
  • For double-point moorings, no swing area appears.
  • If no water depth is available for the mooring, no swing area appears.
• Maximum Scope - This will show swing areas around moorings, using a calculated length for the mooring tackle instead of any actual mooring tackle length that has been entered.  The mooring tackle length is calculated by multiplying the water depth by the maximum scope number that you enter here.
  • For double-point moorings, no swing area appears.
  • If no water depth is available for the mooring, no swing area appears.
• Berth Movement - This shows the movement of berths between their permitted locations and their actual locations (as specified in the database)

Labeling - This field allows you to specify additional information about each mooring that you would like to appear on the map.  You can specify any of the fields in the database, such as the Boat Name, the Owner Name, the Berth Name, etc.  In Google Maps, this information appears in the pop-up window for each mooring.  In Google Earth, this information appears in the pop-up, but can also be displayed on the map itself.  You can only label the Moorings layer, the Selected Moorings layer, or the My Moorings layer.

Coloring - This field allows you to control how the moorings are color-coded on the map.  The "Normal" option displays all moorings the same way.  OnlineMooring also provided the ability to color code the moorings based on whether the moorings are currently in use.  When you choose one of the coloring options, a Legend will appear below the map.  Please contact the staff of OnlineMooring if you would like to color-code using a different database field that does not appear in the list - they can set up additional coloring fields for a small fee.

Preferred Coordinates - This field allows you to specify which set of coordinates you want to use, the coordinates where the berth is supposed to be (the Permitted coordinates), or where the berth is now (the Actual coordinates).  This selection only affects the map when both sets of coordinates have been entered into the database.  If you want to view Permitted coordinates, and only the Actual coordinates are entered into the database, the system will use the Actual coordinates.

Chart Tab

You will see a chart using Google Maps.  In all cases, there will be a link that allows you to view the chart using Google Earth. 

You can do the following on the Chart with the map:

Zoom In - Click on the "+" sign to get a closer look at the center of the map.

Zoom Out - Click on the "-" sign to see more of the surrounding area

Pan - Click the map and drag it to make room for the area you want to see

Get Information - Click on any of the items (such as berths), and a pop-up window will appear with more information about the item.  In some cases, the pop-up window will have a link that will allow you to view all of the information about the item.

Get latitude/longitude - Click anywhere on the map, and the latitude and longitude of that location will appear at the bottom of the page, in the section labelled Cursor Position.

When exiting Google Earth, you will be asked whether you want to save your data.  Please do not save your data.  If you save the data, the next time you come into Google Earth from OnlineMooring, you will get a second copy of map data.  The best case will be that this will slow down Google Earth.  The worst case is that you may be viewing out-of-date data on your map. 

Legend Tab

If you chose any of the coloring options other than "Normal", the meaning of each of the colors will be displayed here.

Coordinates Tab

This section of the page shows you the latitude and longitude for the southwest corner of the map, the northeast corner of the map, and the most recent position where you clicked on the map.

Set Format - This button allows you to change the way that latitudes and longitudes are displayed and entered by default within your site.  This option is only available for people who have administrative rights to the web site.

Center Map - This button allows you to center the map at the latitude and longitude coordinates specified on the "Cursor" row.  You can type any coordinates that you want before clicking the Center Map button.  If you click on the map, the coordinates will change to the coordinates for your cursor position.

Set Bounds - If you have administrative rights, this button will appear.  This will allow you to control the initial area that will be shown on the map.  You can either type the minimum and maximum latitude and longitude, or you can pan and zoom the map until it has the desired area shown.  This option is only available for people who have administrative rights to the site.

How to get to this page

If you have the appropriate security rights, you can get to this page directly from the navigation menu by clicking the Chart link.

You can also get to this page from the Application Search Results page and the Berth Search Results page, by clicking on the Chart link.

Required security access:

No security rights are needed to see the page, but certain features of the page require security rights:

- To see all berths, swing areas, or berth movements, you need All privileges for the Map_View setting.  If you are an inspector and want to see all of the moorings that you inspect, you need Filtered privileges for the Map_View setting. 

- If you are a appilcant nd want to see all of your moorings, you need My Data privileges for the Map_View setting.

- The Set Bounds button requires administrative update privileges on everything
