Starting to use PMGlobe
When you first start PMGlobe, you will be shown a view of the globe
which will normally include your current time zone. Depending on the
time of day, you should see a daylight image of the globe (on the side
facing the sun), a night-time image (‘city lights’, on the dark
side of the globe), or both.
As with most Windows applications, the primary means of controlling the
PMGlobe program is by using the mouse pointer to select menu items,
manipulate the globe image, and so on.
PMGlobe also has a command interface which allows it to be controlled by
typing in text commands (which can also be invoked from programs). This
command interface is described in a later section.
Using the mouse with PMGlobe
Use the mouse with PMGlobe to select menu items and so on, just
as with other Windows applications.
When PMGlobe is visible and the mouse pointer is over the image of
the globe a hover window showing the longitude and latitude
of the pointer is shown (you can turn this off from the
At this point, the left mouse button can be used to select a
geographical location on the globe, and the right mouse button
can be used to pop up a menu of choices, one of which lets you set
the centre point (focus) of the view to the position indicated by the
In more detail:
Right mouse button: setting new viewpoint
To change the view of the globe, move the mouse pointer over a point on
the globe (so that a cross-hair cursor appears) and click the right
mouse button. The top item of the pop-up menu will be ‘Focus’;
left-click on this and the globe will then be redrawn with the
selected point at the centre of the view.
Unless using the circular view of the globe (no fram or background),
you can optionally set the right mouse button from the
Views menu so that it will re-centre (focus) the
globe without using the pop-up menu.
Right mouse button: off-globe pop-up menu
If the mouse pointer is over the window background (off the globe), it
will be shown as a standard arrow pointer instead of as a cross-hair
cursor. In this case, clicking the right mouse button will show a pop-up
menu of options in the usual manner. This pop-up menu exactly duplicates
the menu bar choices; you can remove (or restore) the menu bar using the
Left mouse button: the position/distance calculator
Move the mouse pointer to any visible point on the globe, so that a
cross-hair cursor appears, and click the left mouse button.
This will cause the PMGlobe Position/Distance Calculator window
to appear (if not already visible). You can move the calculator
anywhere on the screen, just like any other window. Then:
You can clear all selected points, including any fixed point, by
pressing the Reset button on the calculator. This also resets
the total track distance to zero, erases any tracks displayed on the
globe, and turns off tracking.
The current position (Latitude and Longitude) of the mouse is
displayed if the mouse is over the globe.
A single click of the left mouse button records the current point on the
Up to two points can be recorded: if two are
shown then the distance between them is also displayed, in kilometres
and miles. (The distance shown is the ‘Great Circle Distance’,
that is, the shortest distance between the points when moving over the
surface of the globe.)
Once a point has been selected, it can be fixed (made into a
base point) by checking the box marked ‘Fix’ next to the
This keeps that point visible on the calculator while you select a
number of other points to measure a series of distances.
Uncheck the box to reurn to normal operation.
If there is no fixed point, you can check the Track box.
any current points and starts tracking new ones: after the first new
point the path (Great Circle route) to each new selection is shown on
the globe, and the total length of the track is accumulated and
Uncheck the box to return to normal operation.
Clicking the Cancel button or pressing the Esc (Escape) key
hides the calculator.
Menu bar choices
The PMGlobe menu choices can be selected from the menu bar (or the pop-up
menu) in the usual way.
They fall into four groups:
Each of the first three groups (and each submenu in each group) has a
summary Help panel as its first selection. The other selections
are described in more detail in the following sections.
- lets you change the window shape and appearance, run macros and
commands, and select other options
- is used to select a fixed viewpoint from which the globe is seen,
change movement settings, or choose the latitude and longitude grid
shown on the globe
- is used to choose the image used for the daylight or night side of
the globe, select sunlight or flat lighting and 3-D shading, alter the
twilight setting, and select the background colour.
- provides an ‘About PMGlobe’ choice, and also brief summaries of
the other menu selections.
