Geodatabase: The ArcGIS Mechanism for Data Management

  1. 1. Geodatabase: The ArcGISMechanism for Data ManagementSabata Mcatshulwa and Liezel Botha
  2. 2. Presentation Outline Cartographic Representations Relationship feature classes Raster Data Complex feature classes Versioning and Distributed GDB
  3. 3. Patterns of an Enterprise GIS Data Management Collect, organise & exchange data Stakeholder Planning & Engagement Analyses Get feedback Transform data and make in to actionable informed information decisions Complete Integrated Systems Operational Awareness Field Mobility Disseminate Get information knowledge into & out of the where & when it field is needed ArcGIS Addresses common organizational needs
  4. 4. Presentation Outline Cartographic Representations Relationship feature classes Raster Data Complex feature classes Versioning and Distributed GDB
  5. 5. Cartographic Representations• For storing Complex symbology Rule-based In the geodatabase Requires an ArcEditor or ArcInfo license
  6. 6. Presentation Outline Cartographic Representations Relationship feature classes Raster Data Complex feature classes Versioning and Distributed GDB
  7. 7. Relationship feature classes • Ensures Referential integrity • Cardinality: − one-to-one − one-to-many − many-to-many • Rule based
  8. 8. Presentation Outline Cartographic Representations Relationship feature classes Raster Data Complex feature classes Versioning and Distributed GDB
  9. 9. Raster Data Raster Datasets • Raster datasets can be: − Individual raster datasets − Mosaicked together − Grouped into mosaic datasets − Grouped into catalogs
  10. 10. Raster DataRaster Catalog − Collection of raster datasets stored in geodatabase − A raster catalog is typically used to display adjacent fully overlapping, or partially overlapping raster datasets without having to mosaic them into one large raster dataset
  11. 11. Raster DataMosaic Datasets• Store, manage, view and query small to vast collections of raster and image data• Dynamic Mosaicking• Optimized Data is stored as a catalog and viewed as a mosaicked image
  12. 12. Demonstration
  13. 13. Presentation Outline Cartographic Representations Relationship feature classes Raster Data Complex feature classes Versioning and Distributed GDB
  14. 14. Complex feature classesTopology• Relationships between coincident features• Ensures data integrity• Rule based − Constrain how features share geometry
  15. 15. Complex feature classesTopology – New 10.1 Tools• Align To Shape• Replace Geometry Tool• Align Edge Tool• Topology Edit Trace Tool• Reshape multiple edges at once
  16. 16. Complex feature classesGeometric Networks• Model common networks and infrastructures found in the real world• Examples: − Water distribution − Electrical lines − Gas pipelines − Telephone services − Rivers/Streams• Network Tracing − Upstream/downstream − Finding connected/disconnected features
  17. 17. Demonstration
  18. 18. Presentation Outline Cartographic Representations Relationship feature classes Raster Data Complex feature classes Versioning and Distributed GDB
  19. 19. Versioning and Distributed GDB
  20. 20. Versioning and Distributed GDB Feature edit tracking Editor • name of the user who created it Tom • date and time it was created Bill Joe • name of the user who edited it • date and time it was last edited
  21. 21. Versioning and Distributed GDB What is a Version?
  22. 22. Versioning and Distributed GDBPrivileges Dialog• See all privileges on a dataset• Bulk grant and revoke to users and roles
  23. 23. Versioning and Distributed GDB Scripting Administration
  24. 24. Versioning and Distributed GDBReplication
  25. 25. Versioning and Distributed GDBArchiving Provides the functionality to record and access changes made to all or a subset of data in a versioned geodatabase• What was the value for a specific attribute at a certain moment?• How has a particular feature or row changed through time?• How has a spatial area evolved over time?
  26. 26. Demonstration
  27. 27. Discussion
