Select the Feature Info button from the Tools toolbar or from the Tools menu, or activate it with the keyboard shortcut CTRL+P
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.
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.
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.
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.
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.
'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.
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.
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
Add and edit per-vertex timestamps by right-clicking on the vertex list and selecting the appropriate option.
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.
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:
Additional modifications can be made from the Overlay
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.
*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:
- Display the Feature Information
- Open Selected Value as Internet URL
- Download File from URL and Load as New Layer
- Open Selected Value as File in Windows
- Open Selected Value as File in Global Mapper
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.
