Feature Info Tool

The Feature Info command selects the Feature Information tool as the current tool. This tool allows you to select vector features (areas, lines, and points) by clicking on or near them. Once selected, a dialog displaying information about the selected item appears. The types of information and selectable features can be limited or expanded.

To pick objects, select Feature Info from the Toolbar or go to Tools and select Feature Info from the menu bar. Press and release the left mouse button near the objects(s) to be picked.

Holding down the 'P' key when left clicking causes only point features at the clicked location to be considered.

If left-clicking on a picture point with an associated image, by default just the image will be displayed, but holding the Ctrl key when clicking will cause the normal feature info dialog to be displayed.

When an object is picked, it will be highlighted and a feature info dialog (picture below) will be displayed. Right-clicking the mouse button cycles through each of the elements located near the selection point, displaying the information in the dialog box.


The object's name, description, geometry information including length and enclosed area (when applicable), attribute value list, and map name, are all displayed.

Attribute List

Right-click on any attribute value to see additional options specific to the selected attribute and attribute value pair*:

Copy Selected Attribute and Value to the Clipboard - Copies the attribute value to the clipboard.

Open Selected Value as Internet URL - Will insert the attribute value into a browser, as if a valid URL.

Download File from URL and Load as New Layer - Will use download link for file, download the file and add as a new layer in the workspace. Must be a File Type supported by Global Mapper for use as a layer.

Open Selected Value as File in Windows - Will open the File inked in the attribute value in Windows. Must be a Windows recognized File Type.

Create New Line with Dist/Bearing/COGO Input from Point - Opens the Coordinate Geometry Input tool to draw a line using distance and bearing from point.

The right-click menu (above) will offer options to copy the selected pair to the Windows clipboard, treat the value as a web URL and open that location in a web browser, or treat the value as a filename (either absolute or relative to the path of the source file from which the feature was read) and load that file either into Global Mapper or with the program associated with that file type in Windows.

'Zoom Map View to Feature Bounds' will zoom the main map view to the extents of the selected feature. The 'Set Current View Projection from Selected Attribute Value' allows the user to export projection to a separate file from a WKT projection string stored in a feature attribute field.  

If the selected feature has an attribute named IMAGE_LINK and the value of that attribute refers to a local image file, Global Mapper will automatically open that image in the associated application, the Ctrl button can be held down to selected the feature and to specify another application to view the image in. An attribute named GM_LINK with the attribute value referring to a local file, will prompt Global Mapper to try and open that file in the current instance of Global Mapper as a new layer.



This button opens the Modify Feature Info Dialog, which allows editing edit the selected feature's information and drawing style.

Delete / UnDelete

This button marks the selected feature as delete. If a feature is already marked as deleted, the button will change to allow for undeleting. Deleted features can be displayed using the Digitizer Options.


For point features the location button will be displayed allowing viewing and modification of the location of the point feature.


Clicking the Vertices button for line or area features displays the Feature Vertex List dialog (pictured below), which allows the user to view, edit, and remove the individual vertex coordinates, including Z and timestamp values (if present) for the selected feature.

The X and Y coordinates are listed in the native projection of the layer, and the Z coordinates will have the elevation units defined for the layer on the Projection tab of the Options dialog for the layer. The user can also easily add per-vertex elevation values to features that do not already have them by pressing the 'Add Elevs' button on the Feature Vertex List dialog.

If timestamp values are present (like for a GPS tracklog), speed and bearing columns will also be displayed for each leg of the feature. Right-clicking on the vertex list for a feature with per-vertex elevations will allow the user to choose the option to evenly spread the elevations to achieve a constant slope between the first and last elevation on the feature and also to replace any zero elevation values by interpolating between non-zero values.

Add and edit per-vertex timestamps by right-clicking on the vertex list and selecting the appropriate option.

Fly-Though Path...

For line features, the button is available to view of set up a fly-through path.


Graphs can be displayed or created from the selected features. See more information about creating Graphs and Charts.

Copy to Clipboard

This button will copy all of the feature information (as text) and the feature itself to the Windows clipboard. It can then be pasted elsewhere, such as in a text editor or as a new feature in a running session of Global Mapper.

View Notation...

This button displays notations that have been created for features in a text editor format. See more information about feature notations.

To select the type of information that will be selected with the Feature Info tool, select the Feature Info tool and right-click on the main map view window (with no features selected).  A context menu containing the following options will be displayed:

Clicking on the menu item will toggle the inclusion of the associated feature type when using the Feature Info tool.

Additional modifications can be made from the Overlay Control Center.

If you right-click on a raster layer in the Control Center, a context menu will allow you to select the option to 'Allow Feature Selection/Search from Selected Layer(s)'. Clicking on this menu item will toggle the capability to select raster pixels in the Feature Info tool for the associated layer.

Special Info Tool Behavior

*When you initially select a feature that has an attribute value of a URL or external file link with the Feature Info Tool, you will be prompted to select a handling method from a dropdown menu in the 'Link Attribute Handling Dialog' (below).

You will be prompted to choose one of the following options:

Handling of these attributes may then be applied to other features with links as attribute values, and alternate handling may still be employed by feature from the right-click menu in the Feature Info Tool.
