  1. GIS Maintenance & Tips Jennifer Kuchar

  2. Maintenance is often the bottleneck of the entire GIS Enterprise Who is responsible for maintenance? There are several possible configurations!

  3. 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

  4. 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

  5. PIN Zoning Address Zoning Spatial Relational Database Management Systems • RDBMS • Types of data • Numeric • Text • Yes/no • Date • Very Powerful • The “glue” of the GIS Assessment PIN Agriculture Assessment PIN Precinct Landuse Planning

  6. 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

  7. Domains • Created in Geodatabase or through ArcToolbox • Add the Coded value or Range of values • Associate Domain to a feature class 570 Parcel Number Point 50 571 Parcel Number Point 100 572 Parcel Number Point 400 579 Parcel Number Condo 100 580 Parcel Number Condo 400 578 Parcel Number Condo 50

  8. Subtypes • One Feature Class • Subtype associated to FC field • Working with subsets • substitutions • Default subtype • Annotation Tools in Arc

  9. Relationship Classes

  10. Tag Data Model • Coincident Geographic Features • The solution is Multiple Feature Tagging Cadastral Feature Class Parcel ROW Lot Subdivision 1 to Many Relationship Table OID Tag Problem Solution Alpha Tag

  11. One Base File Many New Layers

  12. One Parcel… Many Attributes Demographics PIN = 10-01-300-001 Description Acreage Deed Plat Imp. Value Land Value Parcel Number Description Landuse Building Characteristics Agriculture Parcel Number Picture Join, Relate, or View Appraisal Tax

  13. Integration with Tax/CAMA Systems

  14. Workflow Draw Boundaries Enter Core Parcel Data Once Build Feature Classes Complete CAMA Data Entry Roll Data to Tax Administration Publish Maps
