Overview
1. Create a new Codelist in GISDataPro
2. Create Codes
3. Create Attributes
4. Assign Symbology to your codes
5. Save Codelists
6. Transfer Codelist to GS20
Codelists are used to help describe the
data features that you collect GPS data
for, in the field. Leica GISDataPro
software package is used to create or edit
codelists for use with the GIS20.
Open the GISDataPro program.
Create or open an existing Project
File, by selecting New or Open from
File in the Main Menu. Give your
New Project a name, select a
Coordinate System, and set the
Sensor Type to GS20. Set the
codelist selection to none (only when
you plan on creating your own), or
select an existing codelist. Press OK.
Select the TOOLS menu from the
Main Menu, and then choose
Codelist Manager.

Your window should switch from the Main GISDataPro window to the Codelist
Manager window.
Choose Codelist from the Main
menu and then select New
Codelist
Enter a Codelist Name and
Author. Click OK
Your new Codelist file is now created and will be highlighted in the list of Codelists
in the left hand frame of the Codelist window.
Note: When a new codelist is created the first code will always be Waypoint by default and
can not be changed.

enter in the values for your list.
You can set the display properties
that the GS20 uses to display your
features.
Highlight your code from the left
hand frame, then choose Set Display
Attributes from the Code pull down
menu. A new window will pop up
allowing you to change the symbol
properties of the code.
Continue adding attributes for all
your codes that you have in your
codelist.
Continue adding all the attributes to
your codes and then save your
Codelist by selecting Save from the
main menu under File.
Select File, then Close to return to the
main window.
Optional: You can also import Codes from an existing Shapefile.

1) Turn on the unit by pressing and releasing the Power Key, a beep will follow,
then the Leica GS20 start up screen should appear, and then disappear and then
you will be in the Main Menu. The Main Menu provides access to all of the
applications and utilities of the unit. Press the Menu button twice to return to this
menu at any time.
2) In order to collect Data, you must be receiving GPS signal, so ensure that the GPS
Position Icon found in the left corner of the top icon bar is displayed. The symbol
will change from an Autonomous Position Icon to the Real-Time Position Icon as
your GPS signal improved. If there is no position available, check the number of
satellites and the mask angle found in the center of the top icon bar to make sure
you are tracking satellites.
(Make sure the unit is receiving GPS positions and WAAS (Wide Area
Augumentation Signal) before you begin collecting data. The top icon bar will
display this info for you. You should have at least 4 satellites showing under the GPS
Signal Icon, have a good PDOP value displayed below the Real Time Icon, and the
WAAS Real-Time Correction symbol (W Icon) should change from a hollow W(no
signal received) to a solid W(no signal received) (arcs will appear below the Wwhile
it is changing).
