Who is responsible for maintenance?

There are several possible configurations!

Page 3: GIS Maintenance & Tips

Database Design and Infrastructure

Preparation: Understand the current workflow– Take an inventory of documents– Make diagrams : Entity-Relationship & Network

Critique – Ways to improve efficiency– Communication

Decisions– Make a plan and designate a coordinator– Set Goals and a Timeline

Implementation– Contingency Plan– Training

Aftermath– Analysis– Maps

Maintenance Tips

Use the Geodatabase Model– Central Storage– Feature Datasets

Reduce the number of GIS layers “actively” maintained – relationships, domains, and subtypes

Integrate the Tax/CAMA systems with the GIS Utilize the customization abilities in ArcGIS to create

routines or tools that minimize steps– Model Builder

Spatial Relational Database Management Systems

RDBMS Types of data

– Numeric– Text– Yes/no– Date

Very Powerful– The “glue” of the GIS Precinct

Geodatabase Rules

Domains: acceptable values – Range– Coded Values

Subtypes: classification of features within feature class

Relationship Classes: defines a set of valid associations between two feature classes or tables

Page 7: GIS Maintenance & Tips

Domains

Created in Geodatabase or through ArcToolbox

Add the Coded value or Range of values

Associate Domain to a feature class

Subtypes

One Feature Class– Subtype associated to FC field

Working with subsets– substitutions

Default subtype Annotation Tools in Arc
