  • Sample Java source code and tests with sample networks, including double path, parallel path and loops to verify the functionality of the JGraphT library.
  • JPA mapping to a realistic network stored in PostGIS database, tracing test with this database.
  • Short report on single run performance.
  • Output available for visualisation in QGIS.
  • Restful web API to trace upstream or downstream. GeoJSON response.
  • UI component to select node and initiate upstream or downstream trace; integrated in e-envplus/geoadmin interface.
