from Another Area (Add Islands) menu option. You will then need to left-click in the area feature that you
would like to cut the selected area(s) out of.
Splitting Areas into Two New Area Features
You can split an existing area feature into two new area features by selecting the two vertices across which
you would like to split the area, then right clicking and selecting the Split Selected Area at Selected Vertices
menu option. This will generate two new area features by splitting the selected area feature across the segment
between the two selected vertices. Note in some situations you will get invalid areas or no result at all, so be
careful to select vertices for which the connected segment does not cross outside of the area or intersect any
island areas.
Cropping Line Features to Area Features
You can crop or split selected line features to a selected area feature by right-clicking and selecting the option
to Crop/Split Selected Lines to Selected Areas. This will delete any portion of the line feature that lies outside
of the selected areas unless you select the Split option, in which case separate lines will be created for the
parts inside and outside the selected area feature(s). Note that the original line will remain available as a
deleted feature, so you can recover the original line if needed.
Copying Features (Cut/Copy/Paste)
Occasionally you may wish to make copies of existing features or perhaps move features from one instance of
Global Mapper to another. You can easily do this by first selecting the features, then either making a copy of
those features (use Edit->Copy Selected Features to Clipboard menu command or Ctrl+C shortcut) or cutting
those features to the clipboard (use Edit->Cut Selected Features to Clipboard menu command or Ctrl+X
shortcut). Then, simply paste those features into any running instance of Global Mapper using either the
Edit->Paste Features from Clipboard [Ctrl+V shortcut] or Edit->Paste Features from Clipboard (Keep Copy)
[Ctrl+Shift+V shortcut], the latter of which keeps the features on the clipboard for additional pasting rather
than wiping the clipboard clearn.
Snapping to Existing Features When Drawing
During some operations (i.e. drawing new area or line features or graphically placing a new point feature), the
cursor can automatically snap to existing features when you move it near them to facilitate lining up features.
This happens by default unless the ALT or V keys are depressed. Pressing the ALT key causes no automatic
snapping to occur, while pressing the V key causes only vertices on existing features to be snapped to.
Holding down the P key causes only nearby point features to be snapped to.
Note that you can reverse the automatic snapping behavior so that snapping is disabled by default and holding
down the ALT key enables snapping on the Vector Display tab of the Configuration dialog.
ADVANCED USERS: You can customize the pixel radius used when looking for a location on existing
features to snap to using the DWORD registry key 'HKEY_CURRENT_USER\Software\Global
Mapper\SnapToPixelRadius'. The default value is 10 pixels. Just create that registry key and provide the
distance (in pixels) to search from the cursor location for a location to snap to.
