Selected Layers Context Menu

This is a list of the options available by right-clicking on a selected layer or group in the Control Center. You can select a layer by clicking on its name. Multiple layers can be selected using the shift and control keys while clicking on layers in the list.

Many of the options that were previous located here have been moved to the Layer Menu or the Current Workspace right click menu.

Double-clicking on a layer automatically brings up its Options dialog. If you hold down the 'M' key while double-clicking the Metadata dialog for the layer will be displayed instead. Pressing the delete key after selecting layers will automatically unload the layers from the workspace.

Right-click on the selected layers to display a list of options available to perform on the selected overlays. Examples of available options include the following:

Options.... (Double-Click)

Metadata...(Double-Click + M)

Close (Unload) Layer(s)...(DEL)

Remove the selected layers from the workspace.


ZOOM_TO - Zoom to Selected Layer(s)

This causes the view to be zoomed such that the full extents of the selected overlays are visible.

Zoom to Full Detail For Layer (1:1 Pixel Mapping)

This causes the view to be zoomed such that a single sample/ pixel in the selected overlay will take up approximately one pixel on the screen.


GROUP - Set Group to Assign to Selected Layer(s)...

Specify a group to assign the selected layer(s) to. This brings up a dialog to name the group the group for the selected layers. If layers are in a group, they will be organized under that group name in the Control Center and can be easily collapsed into a single item. With a group, the group right-click context menu provides options that operate on all items in the group.

The drop down list will populate with existing group names.

To create multiple levels of nested grouping, insert the word <sub> in between the level names.

In the above example, the control center would contain a group Base Map, with a subgroup Imagery.

To un-group layers, go back to the group properties, and remove the group names so the group field is empty.

DESCRIPTION - Edit the Selected Layer's Description...

This allows renaming the layer. Clicking on a selected layer will also allow editing the layer name. The Layer Description is used in a Legend.

Open Selected Map Folder in Windows Explorer...

This causes the Windows Explorer application to be opened to the folder containing the selected map file.

SELECT - Select All Features in Selected Layer(s) with Digitizer Tool

This option causes all features in the selected layer(s) to be selected with the Digitizer Tool.

Allow Feature Selection/ Search from Selected Layer(s)

This option controls whether or not vector features from this layer can be selected using either the Feature Info or Digitizer Tools.

Allow Export From Selected Layer(s)

By default this option is selected for all layers, un-checking the option will omit the selected layer from any exports. These layers will then show in a different color in the Control Center list.


RECTIFY - Modify Layer Position/ Projection (Re-Rectify)

Use this option to modify the position of a layer using rectification, or to update the existing rectification.

SHIFT - Shift Selected Layer(s) a Fixed Distance or Transform Coordinates...

This option provides a quick way to shift any layer some fixed distance in any direction or to shift layers based on a transformation described in a control point file or via a transformation dialog. When selected a dialog is presented allowing you to select the type of transformation to perform. The following options are available:

  • Shift Layers a Fixed Distance - presents a dialog allowing you to specify the distance to shift the selected layers in the X , Y and/or Z direction or some distance along a particular bearing. For more information see Shift/ Offset Selected Feature(s). Click Apply from this dialog to apply the shift to the layer(s) without closing the dialog.

  • Transform Coordinates Based on File - you will be prompted to select a control point file describing a transformation from the current coordinate system of the file to some new coordinate locations. The file should be a simple comma-delimited text file with each line describing a transformation as follows: current_x,current_y,new_x,new_y. There must be at least 2 transformation lines specified.

  • Specify Coordinate Transformation - allows you to specify a generic coordinate transformation with an offset, scale, and rotation about some point. The information provided should be in the same coordinate system (projection) as natively used by the layer(s) being transformed. You can save the coordinate transformation that you define to a .gm_xform file. If that file is saved alongside a vector file and has the same name (i.e. my_file.gm_xform in the same folder as my_file.dxf), then that transformation will automatically be loaded and applied to the coordinates in the file.

Scale Layer Based on Actual Length of Selected Line

This option allows you to scale a selected layer based on a user-specified length of a selected line feature in that layer. This is useful if you know the actual length of a line feature in a vector layer and want to scale the layer so that the line length is correct without caring about where on the earth the layer is placed. The line that you know the length of should be selected with either the Feature Info or Digitizer Tool.

Set View/ Export Projection to Selected Layer Projection

This option will update the projection that the map is displayed in to match the currently selected layer. The display projection is also the projection used for any exports (that don't require an explicit projection). The current display projection is visible in the bottom bar of the application, and can also be manually changed from the Configuration.


Draw Online Layer Missing Tile Boundaries

Select this option to display tile boundaries with names (zoom, Y, X) when no data is downloaded from the online source. This options helps to troubleshoot problems with custom added online sources.


Edit View Shed Parameters and Recalculate

This allows you to edit the calculation parameters for a view shed layer and then update the results.

Change View Shed Layer Color

This allows you to edit the color used to display the coverage area for a selected view shed layer.


Invert Selection

This option switches the currently selected layers in the Control Center.


Layer Order >

The Layer Order sub-menu provides options for moving the currently selected layer(s).

Reorder Maps by Description/ Resolution/ Location...

This option displays a dialog allowing you to choose a method by which to reorder the maps in the list. This includes sorting alphabetically, by resolution, or spatially sorting the maps.

Move Selected Layers After Another Layer...

This option allow you to modify the order in which overlays are displayed in the main view. This can also be achieved by dragging the layers.

Reverse Order of Selected Layers

This option will invert the order of the selected layers using the same overall layer positions. It will leave any unselected layers in their current position.


Move Selected Overlays to Top of List (Draw First)

This option moves the currently selected layers so they draw first in the display.

Move Selected Overlays to Bottom of List (Draw Last)

This option moves the currently seleted layers so they draw last in the display.
