Basic Operation Leica GS20 Field Guide-1.1.0en 14 1.4 Button Functions 1.4.1 Alpha Numeric Keys Keys 1-9 represent the alpha numeric e ntry keys of the GS20. Similar to a cellular phone, buttons 2-9 co ntain alpha characters; by pressing the key continuously, a ll characters on that key will be scrolled.
Basic Operation Leica GS20 Field Guide-1.1.0en 15 1.4.3 Enter and Escape Similar to standard Windows’ co ntrols, the Enter ke y is used to either accept a choice or adva nce an action. The Escape key functions both as a back ke y, to escape from a current screen; as well as a backspace in edit fields.
Basic Operation Leica GS20 Field Guide-1.1.0en 16 1.4.6 The Main Menu The Main Me nu is the ba se level of t he Leica Ge osystems GS20 user interface. The Main Menu can be quickly accesse d from an application by double clicking the Menu button .
Basic Operation Leica GS20 Field Guide-1.1.0en 17 1.5 Software User Interface 1.5.1 Map Views The map view is the commo n interface on which all main applications are bu ilt. Data Collection, Data Mana gement and Navigation all contain a map interface that has similar con trols and are continuously u pdated, but have indepen dent settings.
Basic Operation Leica GS20 Field Guide-1.1.0en 18 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 lo cation (scaled to 1:20m) awaiting collected data.
Basic Operation Leica GS20 Field Guide-1.1.0en 19 1.5.4 Tables and Filtering Tables ar e used to display mu ltiple attrib ute data th at canno t be directly edited. The table ca n be navigated by the cursor keys (left and righ t being home and end) as well as the overload keys 3 Page Down and 9 Page Up .
Basic Operation Leica GS20 Field Guide-1.1.0en 20 1.5.5.2 T able Filters Table filters allow the u ser to search for da ta based upon the same criteria as listed above in map filters. Once a table is filtered, the user can select from the f iltered table, or view the selected filters in the map view via the context menu choice Table Fea tures .
Data Collection Leica GS20 Field Guide-1.1.0en 21 2. Data Collection 2.1 Job Management When Data Collection is ope ned, if no job is currently selected, the user will be prom pted to either “Open” an existing job or create a “New” job to continue.
Data Collection Leica GS20 Field Guide-1.1.0en 22 2.2 Background Files in the GS20 Often it is important for a user to see th e location of they’re current posit ion and tho se Features they have co llected withi n a larger cont ext. Howe ver, it is not always necessary or even beneficial to have that data selectable.
Data Collection Leica GS20 Field Guide-1.1.0en 23 A status of available memory will be available to provide information on how much informati on can be attached to a job. Memory used in background f iles will affect the amount of map data that can be collected, so be conservative in your estimates.
Data Collection Leica GS20 Field Guide-1.1.0en 24 2.2.5 Viewing the Map If all has gone according to plan, the graphic file will be attached to the current job, an d will be displayed in Map View applications.
Data Collection Leica GS20 Field Guide-1.1.0en 25 2.3 Code Management Because the Leica Geo systems GS20 is designed for GIS data creation and updat e, existing feature layer will be used as a code template for each particular job. Additional codelists can be attached to a job via Codelist Manage r.
Data Collection Leica GS20 Field Guide-1.1.0en 26 2.3.2 Using the Codelist Manager 1. Select T ools from t he Main Menu. 2. Select Codelist Manager, this is the interface you will see. Listed below are the steps fo r codelist creation. We will list them here, an d then look at each on e in depth.

From the mapview, you can ente r features via the context menu, or by just pressing Enter.
Data Collection Leica GS20 Field Guide-1.1.0en 31 2.4.3.1 Point Offsets When a point cannot be collected dir ectly, an offset can be used to collect a point from a more accessible lo cation. Offset information ca n be entered either m anually, or via an externa l rangefinder.
Data Collection Leica GS20 Field Guide-1.1.0en 32 When collecting a point offset, it is important to input the offset data before occupying the auxiliary point. • Azimuth Distance : Enter Azimuth, Distance and Delta Height before occupying the point.
Data Collection Leica GS20 Field Guide-1.1.0en 33 2.4.5 Modes of Collection When a line or area fe ature is selected, the attribution scr een will display the current mode of collection (i.e. stream or node.) The last sele cted mode becomes the de fault by being stored in the user’s recent value file.
Data Collection Leica GS20 Field Guide-1.1.0en 34 Tip: Anothe r way to share a com mon node is by loca ting a new position with the Backward Azimu th and Distance.

Ein wichtiger Punkt beim Kauf des Geräts Leica GS20 (oder sogar vor seinem Kauf) ist das durchlesen seiner Bedienungsanleitung. Dies sollten wir wegen ein paar einfacher Gründe machen:
Wenn Sie Leica GS20 noch nicht gekauft haben, ist jetzt ein guter Moment, um sich mit den grundliegenden Daten des Produkts bekannt zu machen. Schauen Sie zuerst die ersten Seiten der Anleitung durch, die Sie oben finden. Dort finden Sie die wichtigsten technischen Daten für Leica GS20 - auf diese Weise prüfen Sie, ob das Gerät Ihren Wünschen entspricht. Wenn Sie tiefer in die Benutzeranleitung von Leica GS20 reinschauen, lernen Sie alle zugänglichen Produktfunktionen kennen, sowie erhalten Informationen über die Nutzung. Die Informationen, die Sie über Leica GS20 erhalten, werden Ihnen bestimmt bei der Kaufentscheidung helfen.
Wenn Sie aber schon Leica GS20 besitzen, und noch keine Gelegenheit dazu hatten, die Bedienungsanleitung zu lesen, sollten Sie es aufgrund der oben beschriebenen Gründe machen. Sie erfahren dann, ob Sie die zugänglichen Funktionen richtig genutzt haben, aber auch, ob Sie keine Fehler begangen haben, die den Nutzungszeitraum von Leica GS20 verkürzen könnten.
Jedoch ist die eine der wichtigsten Rollen, die eine Bedienungsanleitung für den Nutzer spielt, die Hilfe bei der Lösung von Problemen mit Leica GS20. Sie finden dort fast immer Troubleshooting, also die am häufigsten auftauchenden Störungen und Mängel bei Leica GS20 gemeinsam mit Hinweisen bezüglich der Arten ihrer Lösung. Sogar wenn es Ihnen nicht gelingen sollte das Problem alleine zu bewältigen, die Anleitung zeigt Ihnen die weitere Vorgehensweise – den Kontakt zur Kundenberatung oder dem naheliegenden Service.
