The German Environmental Agency has implemented a geo portal application to meet the European Union regulation for a Pollutant Release and Transfer Registry (PRTR). It is based completely on Open Source software running Debian, Postgres and the OSGeo SDI stack with PostGIS, MapServer, Apache and Mapbender.

The background maps have been created from OpenStreetMap data. The data has been generalized and processed to meet the performance needs of the application. Maps are rendered using MapServer and served through the OGC WMS standard. The application meets the European INSPIRE directive and PRTR.

Many SDIs and geoportal applications operated by the German government already rely completely on Free and Open Source Software. On top of this the PRTR portal uses now also uses freely available community crowd based spatial data as background maps.

Case Study Pollutant Release And Transfer Registry

  1. 1. Case Study: PRTR  Pollutant Release and Transfer Registry Germany Copyright: WhereGroup GmbH & Co. KG. GNU FDL License http://www.gnu.org/licenses/fdl.txt    FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 1/16
  2. 2. The Problem What is PRTR? Pursuant to the European PRTR regulation Germany is  bound to report the release of industrial pollutants into  air, water and soil and the amount of waste disposal  and contaminants in waste water. As as a European member state Germany also has to  provide a mechanism that will allow the European  Environmental Agency to access this data pursuant to  the INSPIRE directive  (for example as a web service).

  3. 3. The Solution Web interace for Citizens On June 3rd the web site:   http://www.prtr.bund.de was  launched to publicly provide  this information to the  citizens.  Behind  the  application  works  an SDI. FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 3/16
  4. 4. Spatial Data Infrastructure Schematic  diagram of a  spatial data  infrastructure FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 4/16
  5. 5. Implemented Standards and Software Under the Hood The mapping component of PRTR was implemented by  the WhereGroup in close cooperation with the German  Federal Agency for Agriculture and Food on behalf of  the Federal Environmental Agency. The solution is implementated with proven Open  Source software using international Standards and  in  consideration of the INSPIRE directive.  FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 5/16
  6. 6. SDI with OGC WMS Schematic view of a simple  OGC WMS getMap request in  a spatial data infrastructure. FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 6/16
  7. 7. Standards und Software The Software The mapping application was deployed with the  geoportal framework that orchestrates the OGC WMS  services of the Federal Agency for Agriculture and Food. ● Mapbender  ● UMN MapServer  ● PostgreSQL / PostGIS  All software of the geoportal shall support the  requirements of the INSPIRE directive. FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 7/16
  8. 8. Cluster­Architektur Virtualised Server Architecture The software runs on a  performance optimized  and load balanced 100  CPU ESX cluster  architecture. During the first three  days of operation the  infrastructure served  5 million maps, with a  peak of 250,000 per  hour at 72% load. FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 8/16
  9. 9. Background Maps Optimizing Community Map Data The background map of the PRTR application is based  on OSM (OpenStreetMap) data that has been  optimized to generalize roads and land cover. The map  service is split into 5 zoom levels each of which draws  data from a separate physical table. The data was  generalized using simple PostGIS SQL simplify  commands. It was decided to use a database to allow  for differential updates of the OSM data.  FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 9/16
  10. 10. Legal Stuff – Copyright Legal Background and Copyright ● The  application  PRTR  is  published  by  the  Federal  Environmental  Agency  (UBA).  The  UBA  owns  the  copyright of the application.  Pollutant locations:  ● The locations of the polluting  Copyright UBA industry  are  operated  as  an  OGC  WMS  service.  It  can  be  accessed  directly.  The  copyright  of  this  service  is  also owned by the UBA FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 10/16
  11. 11. Legal Stuff – CC by SA License Copyright and license of the OSM Data ● The OSM data underlies the  OSM based maps:  Creative Commons CC by SA  Copyright CC by SA license. All derivative works  using that data thus also  have to be published under  the same CC by SA license.  FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 11/16
  12. 12. Legal Stuff – Public Domain Postal Codes from Public Domain ● The postal codes have been  Postal Codes:  taken from pulic domain.  Public Domain They are barely to be seen  and are mainly used for  navigation purposes. FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 12/16
  13. 13. Open Issues Combined Copyright Combining the three data  sources into a new map  dreates a derivative of the  OSM data. This might  cause multiple coypright  and license issues, therfore  the application as yet lacks  server side PDF generation Blog: http://arnulf.us/sevendipity/archives/20­Copyright­in­a­Shrapnel­Shell.html  FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 13/16
  14. 14. Open Issues Data Quality Assurance Simplifying the data showed issues with the structural  integrity of the data which only became apparent through  the use of standard technology.  FOSS4G 2009, Sydney, Australia Arnulf Christl, WhereGroup Bonn 14/16
  15. 15. FOSS, Standards and Crowd work! Summary ● The mapping requirements of a federal agency can be  addressed with Open Source Software (we knew  that...) and crowd sourced data (that is good news!).  ● The application is fully scalable and stable. ● Some Homework needs to be done wrt copyright and  licensing (we already knew that...). ● Consequent application of international standards  caters for hight interoperability, security of investment  and INSPIRE compatibility.
