on the map screen.
Setting General
Parameters
1. Tap Menu>Options.... A new screen is displayed on which
you can choose the measurements units:
• Linear units: Choose between kilometers/meters, miles/
feet or miles/US feet.
• Area units: Choose between square meters, square
kilometers, hectares, acres, square feet, square yards
or square miles.
2. Tap on the Antenna tab and then enter the vertical distance
you will maintain between the top of the receiver (where
the GPS antenna is) and the ground while executing the
job.
This value has to do with your own size since you will be
holding the receiver in your hand throughout the job.
Enter the distance value according to the selected linear
unit. This setting makes sense only for 3D jobs. It can be
ignored for 2D jobs.
3. Tap on the View tab located at the bottom of the screen. A
new screen is displayed allowing you to orientate the map:
• North Up: Map orientation is fixed. The top of the map
screen will always give the North direction.
• Course Up: Map orientation will change as you walk.
The map will rotate in order to have your course always
orientated upward on the map screen. This option
cannot be used if a georeferenced background map is
displayed.
4. Tap on the Filter tab and then enter the maximum
permitted PDOP value. No features can be collected when
the PDOP exceeds this value (default: 100). A good
geometry of satellites usually gives PDOP values less than
5.
5. At the bottom of the screen, scroll the list of tabs to the
right until you can see the Keyboard tab. Use this tab to
enable or disable the large on-screen keyboard. The large
keyboard is only available for use within the
MobileMapper Field application. Only the Microsoft
smaller keyboard can be used when working from within
the operating system.
6. For background maps ( Map tab), see Adding Background
Maps on page 20.
7. Tap OK to validate all your choices.
