6. GLOSSARY
2D/3D GPS reception
The GPS receiver uses satellite signals to
calculate its (your) position and needs at
least four signals to give a three-dimensional
position, including elevation. Because the
satellites are moving and because objects
can block the signals, your GPS device might
not receive four signals. If three satellites
are available, the receiver can calculate the
horizontal GPS position but the accuracy is
lower and the GPS device does not give you
elevation data: only 2D reception is possible.
Active route
The currently navigated route. Whenever the
destination is set, the route is active until you
delete it, reach your destination or you quit
MMES. See also: Route.
City Center
The city/town center is not the geometric
center of the city/town but an arbitrary point
the map creators have chosen. In towns
and villages, it is usually the most important
intersection; in larger cities, it is one of the
important intersections.
Color theme
MMES comes with different color themes for
daytime or night use of the map and menu
screens. Themes are custom graphic settings
and they can have different colors for streets,
blocks or surface waters in 2D and 3D modes,
and they display shades or shadows in
different ways in 3D mode.
One daytime scheme and one night scheme
is always selected for the map and for the
menus. MMES uses them when it switches
from day to night and back.
GPS accuracy
Several factors have impact on the deviation
between your real position and the one given
by the GPS device. For example, signal delay
in the ionosphere or reflecting objects near
the GPS device have a different and varying
impact on how accurately the GPS device can
calculate your position.
Map
MMES works with digital maps which are not
simply the computerized versions of traditional
paper maps. Similarly to the paper road maps,
the 2D mode of digital maps show you streets,
roads, and elevation is also shown by colors.
In 3D mode, you can see the altitude
differences, for example valleys and
mountains, elevated roads, and in selected
cities 3D landmarks and 3D buildings are also
displayed.You can use digital maps interactively: you
can zoom in and out (increase or decrease
the scale), you can tilt them up and down, and
rotate them left and right. In GPS-supported
navigation, digital maps facilitate route
planning.
North-up map orientation
In North-up mode the map is rotated so its top
always faces North. This is the orientation for
example in Find on Map.
Road Safety Camera
Special alert points for speed, red light or
bus lane cameras. Different data sources
are available. You can configure MMES to
warn you when you approach one of these
cameras.
Detecting the location of Road Safety Cameras
is prohibited in certain countries. It is the sole
responsibility of the driver to check whether
this feature can be used during the trip.
The software is capable of showing and
warning for more than just cameras. Various
other types of proximity alert points like
school zones and railroad crossings are also
available.
Route
A sequence of route events, i.e. maneuvers
(for example, turns and traffic circles) to reach
the destination. The route contains one start
point and one or more destinations. The start
point is the current position by default. If you
need to see a future route, the start point can
be replaced with any other given point.
