1.5.2 GPS Symbol and Zoom Controls
By default, an open mapping screen zooms to the full extent
of data in a job; however if no data exists, the map will be
centered on the GPS location (scaled to 1:20m) awaiting
collected data.
The map submenu contains zoom controls for
• Zoom In, Zoom Out, Zoom To Full Extents
• Center Cursor, Center GPS, Center Selected
• Autopan GPS
Remember: “3” and “9” function as zoom controls !
Remember: The mapview is only capable of displaying
12,000 nodes, being points or line/area
verticies. A warning will be issued at 9500
nodes, that the map will be discontinued. A final
warning will be issued before the map display is
turned off.
Tip: To minimize nodes in a job; consider streaming lines
and areas by distance or at a slower rate. An 8 hour
constant collection at a 5 second interval only produces
5760 nodes.

The map display can be turned off in the Job
Management Screen.
1.5.3 Context Menus
The context menu in the Leica
Geosystems GS20 functions
similarly to a Windows’ context
menu, however the right mouse
click is replaced with the Menu
button. When the Menu button is depressed, a list of choices
will be displayed based on the application and the actions
taken.
• Choices in the context menu can either be selected using
the cursor arrows (Left and Right being home and end) or
directly accessed via the number keys.
• To simplify submenus appear where common groupings
exist such as map control functions. The submenu is
denoted with a right arrow and is accessed via enter or the
number key. In some instances, sub-submenus exist.
