    • CONNECT. TRANSFORM. AUTOMATE. Background We are from the Swedish University of Agricultural Sciences
    • CONNECT. TRANSFORM. AUTOMATE. Background Data and researchers in Sweden

    • 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)
    • 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!
    • 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)
    • 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)
    • CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (SpatiaLite) However, FME does not read as efficiently as other formats
    • CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (SpatiaLite) does not set spatial index
    • CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (SpatiaLite) Can fix
    • 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)
    • CONNECT. TRANSFORM. AUTOMATE. Tricks of the trade (KML network link) KMLs are nice for reporting
    • CONNECT. TRANSFORM. AUTOMATE. Results 23 Universities 100K distributed data sets ( 400 * total area of country) 6000 Unique users Image courtesy of saamiblog (CC BY 2.0)
