  • #3 – Spatial ETL and Data Validation Slide
  • #3 – Spatial ETL and Data Validation Slide
    • Problem
      • Utility workers are out during the day collecting data.
      • Historically data validation is done overnight.
      • Data issues means another trip to the site.
  • #3 – Spatial ETL and Data Validation Slide
    • Solution
      • Spatial ETL Server technology enables users to validate data from the field.
  • #4 - Spatial ETL and MetaData
    • Problem
      • As more data becomes available on the web metadata becomes more important.
    • Spatial ETL and MetaData
      • Metadata is simply another type of data for Spatial ETL Technology
    • Solution
      • Use Spatial ETL Technology to publish data and associated metadata to the web.
      • Use Spatial ETL technology to retrieve metadata and data.
  • #5 Spatial ETL Consuming Web Services Problem: The number of web services is growing quickly. Spatial ETL makes it easy to leverage services in your applications.
  • Spatial ETL for fun! Data Streaming
    • Problem
      • Celebrities are the single biggest threat to our children today. 
      • We need to keep these people away from our children.
  • Spatial ETL for Fun! Data Streaming
    • Resources
      • We bought them all nice fashionable ankle bracelets which they love!
      • What they don’t know is that the purse has an embedded GPS device!
    • Solution
      • Use Spatial ETL to deliver location data to users!
  • Simple Real World Data Streaming
  • Conclusion
    • Spatial ETL is about moving data so that users can exploit power of other tools
    • Transformation is the key. Deliver information needed not just raw data.
    • Spatial ETL plays both a consumer and supporting role for web services.
