2.3Code 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.

2.3.1Creating 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.
