Chart and Object Information

The Chart and Object Information tool allows you to obtain detailed information about objects and chart cells at a specified point on the chart.

Tool activation

The tool is activated by clicking the information icon in the tool selection menu. The ECDIS cursor will change to .

Obtaining information

To obtain information, left-click (tap) the point of interest on the chart. The bottom window will display a tree with information.

Information interface elements

№	Element	Description
1	Query point coordinates	Displays the coordinates of the point being queried Format: latitude and longitude in the selected coordinate system
2	Chart	ENC cell name Expanded by left-clicking (tapping) the row
3	ENC cell	Displays the ENC cell name and its attributes for which object information is being queried. If there are larger-scale ENC cells under the queried position, data will only be collected from the displayed cell
4	Objects	Expandable section with a list of chart objects Expanded by double-clicking (double-tapping) the row Contains all objects located at the specified point
5	Object list	List of all chart objects at the specified coordinates Displayed when the “Objects” section is expanded Detailed attributes can be obtained for each object
6	Selected object indication	Visual highlighting of the selected object or chart cell in the chart window The object is highlighted on the chart when selected in the list
7	Highlight (active)	In active highlight mode Area objects are highlighted with a background Allows visual identification of objects on the chart
8	Point object highlight	In active highlight mode Point objects are marked with a cross Helps quickly locate an object on the chart by its symbol
9	Highlight (inactive)	In inactive mode Object highlighting is turned off Used to disable visual indication

Magnetic variation information (MAGVAR)

Magnetic variation (MAGVAR) is displayed in the information window. Double-clicking (double-tapping) the row opens a window with more detailed information.

For detailed information about magnetic variation, see the Magnetic Variation section below.

Important

Only one object can be highlighted at a time!

When a new object is selected, the previous one is automatically unhighlighted.

Detailed object information

Detailed information can be obtained for each chart cell or object present in the table. To do this, double-click (double-tap) the entry of interest, after which a window with attributes and their values for the selected object or chart sheet will be shown.

Chart cell attributes

The window contains detailed information about the selected ENC cell, including:

• Cell name

• ENC compilation scale

• Issue date

• Update status

• Additional metadata

Object attributes

The window contains all attributes and their values for the selected object:

• Object type

• Category

• Description

• S-52 symbol

• Associated (dependent) objects

• Additional characteristics

Magnetic Variation

If the ENC cell contains encoded magnetic variation data, the data will be displayed in the information window.

Information content:

• Magnetic variation value for the given area

• Year of magnetic variation determination

• Annual rate of change

• Data accuracy

• Information source

Tidal Currents

If the ENC contains encoded tidal current data, the data will be displayed in the information window as a tidal stream table.

Information content:

• Tidal current data at the specified point

• Current speed

• Current direction

• Tide phases

• Temporal characteristics

Graphical Information

Chart objects may contain additional graphical information, for example: information from navigational publications or graphical representation of an object.

When external data is available, a corresponding entry will be displayed in the window. To view:

1. Double-click to view extended information

2. Then double-click the entry with the image in graphical format

Operating features

Viewing modes:

• Cell list: view all ENCs at the query point

• Object list: view all chart objects at the point

• Detailed information: view attributes of the selected item

Interactivity:

• Clicking a row in the list highlights the object on the chart

• Double-clicking opens the detailed information window

• Highlighting can be turned on/off for visual control

Tip

Use the information tool for quick access to data about objects on the chart without the need to construct graphical elements.

The tool is especially useful when working with navigational objects, buoys, lighthouses, and other ENC elements to obtain their exact characteristics and purpose.

Note

All objects and chart cells displayed in the information window correspond to the current chart scale and selected display settings. When the scale or display settings change, the list may be updated.

Note

ASM and AIO data are also displayed in this window.
