Normally, StruMap is used with a single map window: this is the default configuration.
Map windows may be added as required. It is especially useful to use two map windows when using Compare Two DataSpaces.
Map windows may view the same or different data, and may be locked in view extents so that the same view of different data may be used.
A new map window may be created by using the File > New Window menu option, via the New Window dialog box, or from the Environment Manager.
Map windows may be removed by closing them using the
button in the title bar,
using the File > Close or File > Close All Windows menus,
or from the Environment Manager.
Map windows may be tiled or overlapped by use of the
Window options on the
Main Menu. Non-maximised map windows may be resized by positioning the
cursor over the window frame: the cursor changes to either
or
: press and hold the left mouse button to
resize the windows.
Two windows may be set to track each other so that as the view changes in one window the other window automatically follows: this is enabled using the Environment Manager.
DataSpaces are managed by the tabs across the bottom of the map window. To change the active DataSpace, simply left-click the appropriate tab. The map window will redraw with the new active DataSpace.

If this is clipped by the horizontal scroll bar, move the mouse between the
two until the cursor changes to
: press
and hold the left mouse button and drag the divider to a suitable position, then release
the mouse button.
There is a right click menu on the tabs, whose options are as follows:
This is particularly useful in two cases:
A similar arrangement exists for the background vector data, called CMF Space. It is very rare that this is used.
A similar arrangement also exists for the background raster data, called Raster Space, but a map window may only have a single Raster Space.
When working with utility network data, it is often useful to view other utility data in relation to the main network. This can be achieved by creating the following DataSpaces:
![]() |
|
![]() |
|
To examine a particular DataSpace, ensure that the appropriate tab is active.
Two map windows may easily be set up like this:
Create the second window using the File > New Window menu, via the New Window dialog.
Use the Environment Manager to lock the view of the two windows.
Control the DataSpaces within each window by the DataSpace Tabs of the map window.
For information on how the mouse is used within the map window, please refer to the The mouse within the map window, Finding items and Digitising items topics within the Introduction.
