• Move Selected Vertices - This option allows you to move selected vertices to a new location. To do
this, simply hold down the left mouse button and move the vertices to the desired location, then
release the left mouse button. You can continually to refine the location by repeating. Right clicking
or pressing the ESC key will complete the operation. Note that while moving a single vertex, you can
use the Snapping feature to help align the vertex with existing features. If you'd only like to move the
selected vertices either horizontally or vertically, you can hold down either the 'X' or 'Y' keys on the
keyboard to restrict the movement to that axis. Holding down both keys will move the vertices
diagonally.
• Join Selected Vertices - This option allows you to set multiple vertices to the same location, which is
handy for ensuring that there are no gaps along the seams of features. Once you've selected this
option, hold down the left mouse button and move the vertices to the new desired location, then
release the left mouse button. Right click or press the ESC key to complete the operation once you're
done. Note that while joining vertices, you can use the Snapping feature to help align the vertices with
existing features.
• Deleted Selected Vertices - This option allows you to delete the selected vertices. To quickly do this
without using the right-click menu, the CTRL+Delete hot key will also delete selected vertices.
• Set Position of Selected Vertices - This option displays a dialog allowing you to manually position the
selected vertices by entering their new position in either latitude/longitude coordinates or coordinates
in the currently configured view projection/datum. If the selected vertices are from a 3D line or area
feature, you will also be able to set the elevation value to use for the vertex.
• Insert Vertex - This option allows you to insert a new vertex into the selected area or line feature. To
insert the vertex, select the menu option, then left click at the location where you want the new vertex
inserted. The vertex will be inserted on the area or line feature at the clicked location along the nearest
segment of the feature. Alternately, if you hold down the SHIFT key while left-clicking the new
vertex will be placed on the selected feature(s) at the nearest location to the click location. You can
also use this feature to extend features. The newly created vertices will be automatically selected. If
you need to add multiple vertices to the selected feature(s), simply hold down the 'I' key when
left-clicking to place the vertex and you will remain in the insert vertex mode.
• Resample Selected Feature(s) at Specified Spacing - This option is found under the Advanced Feature
Creation Options submenu and allows you to resample your selected area or line feature at a specified
interval. This is useful if you want to add a lot of new vertices along your feature to make reprojection
work better or to facilitate smoothing of the feature.
• Simplify (Reduce) Vertices of Selected Feature(s) - This option allows you to automatically remove
vertices that do not significantly contribute to the shape of your selected area or line features. This is
useful to significantly reduce the size of your features without giving up much detail in the shape.
When selected you will be presented with an option to specify how different from a straight line a
vertex has to be in order to be kept.
• Smooth Selected Line/Area Feature(s) - This option allows you to modify the position of the vertices
of your selected line and area features to smooth the appearance. This can be useful on things like
jagged contour lines to give them a better appearance.
If after modifying the shape of an area or line feature you decide that you want to undo the changes and
restore the feature to its original shape, simply select the feature(s) that you want restored and select the
Restore Original Shape from the right-click popup menu.
Rotating and Scaling Features
Global Mapper User's Manual
When you have one or more features selected, you can right click and select the Rotate/Scale Selected
Features command to bring up the Setup Rotation and Scaling dialog (pictured below). This dialog will allow
you to rotate and scale the selected features about a point that you select.
