  12. 12. CONNECT. TRANSFORM. AUTOMATE. FME server Rest API Token service /fmetoken/service/generate HTTP get /fmerest/repositories/" + your_fme_repo_name + ".json Tricks of the trade (Servlet) Image courtesy of abraham.williams (CC BY 2.0)
  13. 13. CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (Shutdown Python script) To enable unsupported functions Zip & Email & Remove files that have been downloaded, Anything you want!
  14. 14. CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (External script example 1 handout) Use an external script to enable faster debugging Monkey patch sys or import something from path (yes we actually use the linux version)
  15. 15. CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (SpatiaLite example 2 handout) Wonderful format for mixed environments We have Qgis, Arcmap, FME, they all read it! Image courtesy of juicyverve (CC BY 2.0)
  16. 16. CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (SpatiaLite) However, FME does not read as efficiently as other formats
  17. 17. CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (SpatiaLite) does not set spatial index
  18. 18. CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (SpatiaLite) Can fix
  19. 19. CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (Google Fusion Tables) Fusion tables are nice for reporting But often writes fail (we do not know why, reported the issue)
  20. 20. CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (KML network link) KMLs are nice for reporting
