Presentation Transcript

  1. Introducing the Geodatabase

  2. Introducing the Geodatabase • Geographic Database – geodatabase • Storing spatial and attribute data • Container for spatial and attribute data (tables) • Scaleable (one user to multiple users) • Supports data integrity • Stores topology and relationships

  3. Spatial Data Formats Raster • TIFF and JPEG • Example: Nautical Charts, DRG, DOQQ • ESRI GRIDS • Example: Digital Elevation Models (DEMS) Vector • ArcInfo Coverage (1983) • Supports topology • Shapefile • Does not support topology • Geodatabase (1999)

  4. Diagram of the Physical Database MarineFeatures NavFeature Trackline Waypoints MarineReserve

  5. Shapefiles Geodatabase

  6. Weakness • Not backward compatible • Takes time to build the model • Purchase of software and hardware for multiuser implementation.

  7. Benefits • More sophisticated analysis and editing • Relationships, topology, attribute validation • Better organization of data • Multiuser editing
