Leveraging FME Workbench and Python Scripts to Create Stylized Oil and Gas KMZ Datasets

  1. 1. CONNECT. TRANSFORM. AUTOMATE. LEVERAGING FME WORKBENCH AND PYTHON SCRIPTS TO CREATE STYLIZED OIL AND GAS KMZ DATASETS MARCO A. TERRAZAS GIS ANALYST
  2. 2. FGDB to KMZ
  3. 3. Startup & Shutdown Python Scripts - FME allows us to run python scripts before and after a translation. - This is very useful because you can carry out maintenance tasks on your datasets before they are pushed into a different format. - In this example I will be compacting the FGDB before the translation then call a batch file to clean up the FME’s log after the translation.
  4. 4. Startup Python Script - The following python script “compacts” our main data source, the FGDB. - A regularly used FGDB should be compacted periodically as the records on the database lose their order and unused space is developed. This affects the reading performance as the file system needs to work harder to catch up. - ESRI recommends compacting your databases once a month if you delete and add data frequently.* Which is often the case if you perform surveyor pipeline and facility updates. * © ESRI compacting file and personal geodatabases: http://webhelp.esri.com/arcgisserver/9.3/dotnet/index.htm#geodatabases/compac-1530230024.htm
  5. 5. FME Workbench 2 (Pipelines) FGDB Reader Reprojection: NAD27 -> WGS84 As-Built Test: PL is Existing (Not Surveyed) Symbolization (Colors/Styles) Export all KMLs Into a single KMZ Test: PL is As-Built (Surveyed) Test: PL is in Construction
  6. 6. EsriReprojector Transformer The EsriReprojector transformer reprojects feature coordinates from one coordinate system to another using the Esrireprojection library.* Don’t forget your Geographic Transformation! *© Safe Software EsriReprojector Reference: http://docs.safe.com/fme/html/FME_Transformers/Default.htm#Transformers/esrireprojector.htm
  7. 7. FGDB Projection: NAD_1927_StatePlane_Texas_South_Central_FIPS_4204
  8. 8. Google Earth Projection Google Earth uses Simple Cylindrical (Plate Carree) projection with a WGS84 datum for its imagery base* *© 2014 Google Earth Projection: https://support.google.com/earth/answer/148110?hl=en
  9. 9. KMLStyler Transformer The KMLStyler transformer allows us to create a common symbology for a set of features.* Color Icon Line Style Label Style * © Safe Software KMLStyler Reference: http://docs.safe.com/fme/html/FME_Transformers/Default.htm#Transformers/kmlstyler.htm
  10. 10. FME Workbench 1 (All Features) Well Pads Offices Leases Facilities Pipelines
  11. 11. Shutdown Python Script - The following python script runs a batch file named “LogClipper.bat” after the translation is done. - Once the batch file runs the Python script closes. - more +94 command: Using the original FME log file “Pipelines.log” it creates a “Pipelines.log.new” file which only shows the logs data from line 95 down to the end of the log. - Move /y command: Replaces the original log with the new condensed version. - Notepad opens showing the clipped log containing the feature counts. LogClipper.bat
