Evolution of Esri Data Formats Seminar
The seminar outlines the evolution of ESRI data formats, covering legacy formats like ArcInfo and shapefiles, current formats such as geodatabases, and future trends in data handling and service delivery. The discussion emphasizes the advantages and limitations of various formats, including the enhancements offered by geodatabases for multi-user editing and spatial data management. Additionally, it highlights the impact of mobile and cloud technologies on data access and usage in organizational and societal contexts.

- 9. Legacy Formats • ArcStorm: − Central storage and checkout editing − Coverage based − Tile structure − Pessimistic locking of Tiles − Checked out Tiles not available to other users − Mapped network drives − No Relational database − Initial concepts for SDE
- 10. Legacy Formats • ArcSDE: − Store Spatial data in a Relational Database − Oracle, Informix, DB2 − Utilise Spatial Types (OGC) − No Geodatabase functions − No Feature Datasets − Allow raster storage − Rasters fast, but large. − Raster duplication.
- 11. Legacy Formats • Shapefilelegacy: − Simple geographic data format − Big Demand for simple storage − Open Exchange format − Adopted as standard − Interoperability buzzword − Point, Line and Polygon only
- 12. Demonstration • ArcInfo Workstation •ArcView 3.2
- 13. Current Formats Overview •Organization: − Projects, Departments, Enterprise • User: − Analysis and Consume • Shapefile limitations • Geodatabase advantages • Services • Mobile • Cloud
- 14. Organizational Use • Projects − Shapefiles and File Geodatabase • Departments − Geodatabase (Oracle, SQL…) • Enterprise − Geodatabase (Oracle, SQL…) − Services (ArcGIS Server) Project Department Enterprise
- 15. Shape file Limitations • No Topology • No Attribute validation • Size limitation (2GB) • No complex geometry • No multiuser editing To Geodatabase • No Annotation Shapefile • DBF Limitations − Data types e.g. date/time − Field names 10 chars Shapefile − Blobs Not using full potential of ArcGIS
- 16. Geodatabase Advantages • Whatis a Geodatabase? − Central storage and management location for rich collection of spatial data, − Sophisticated rules and relationships. − Geoprocessing and symbology.
- 17. Geodatabase Advantages • Whyuse a Geodatabase? − Integration with RDBMS (Oracle, SQL..) − Multi-user editing (versions) − Topology rules and behavior − Attribute validation (domains) − Greater storage capacity − Lower storage requirements − Optimized performance − Scalable (File GDB, SQL Express, Enterprise) Leverage full potential of ArcGIS!!

- 19. Geodatabase Design • Domains,Attachments and Aliases − Utilize on multiple platforms − Design for editing in Desktop − Design for Server applications − Design for Mobile Validation in Attributes dialog box Validation in attribute table
- 20. Feature Dataset defined •Logical grouping of Feature Classes that participate in a behavioral function e.g. Topology. • Common coordinate system for all contained Feature Classes. • User permission set on Feature Dataset level. • Feature Class name unique in Geodatabase, not in Feature Dataset. • Not to be used to organize data – not a directory!
- 21. Services • Dynamic Services − Live content from Geodatabase − View updates − Interrogate data • Cached Services − Predefined Tile schema at various scales − Stored as images in Tile structure • Image Services − Single or mosaic images served
- 22. Mobile • Mobile (GPS) − High accuracy devices − Data capture − Ruggedized − Purpose driven − Workflow − Geodatabase design • Mobile (Smartphone) − Windows, Apple, Android − Executive monitoring − Planning − Geodatabase design
- 23. Online (Cloud) content •Online content − Image and Street − Desktop, Server, Mobile − Online access control • Subscription − Personal − Organization − Upload data/proc − Applications and Dashboards
