2.3 Code Management
Because the Leica Geosystems GS20 is designed for GIS
data creation and update, existing feature layer will be used
as a code template for each particular job. Additional codelists
can be attached to a job via Codelist Manager.
In order to protect database integrity, a consistency check is
performed when codelists are attached to a job. If the same
code occurs in both the feature table and the codelist, the job
feature data will be used.
Codelists can be attached and detached as well as created
and modified from the Codelist Manager in the MAIN menu.
2.3.1 Creating Codelists
What is a Code? Codes are used to describe objects of the
same type. The code in GIS DataPRO is equivalent to the
Theme in ArcView 3.2. Each code has it’s own type, with only
one type per code: point, line or polygon For example: Tree
(Point), Roads(Line), Parcels(Polygon).
A code contains attribute information that may be assigned to
the Codes (points, lines or areas) during measurement in the
field.
For example: Fire Hydrant (Code): Serial Number and Color
(Attributes).
A Codelist contains codes to be collected in a job, and is
attached to a job.
A codelist can be created in three ways:
1. Create your own codelist/code.
2. Copy another codelist/code from another project.
3. Import codes from existing shapefile.
Codelists are created in the Codelist Manager in GIS
DataPRO.
