FME Usage in GeoArchive, Geodetic Survey Process Management Presentation Transcript

  • 1. CONNECT. TRANSFORM. AUTOMATE. GeoArchive Hannu-Pekka Rantaniemi Jüri Lippus CEO, Spatialworld Oy Senior Consultant, Affecto OÜ
  • 2. Spatialworld Oy ! Founded 1994 as Smallworld Finland, reseller and support organisation for Smallworld products. Nasdaq 1996 with Smallworld, GE 2000, MBO 2002, FME 2004, SpatialBiz plug-ins 2013. ! Related to Safe Software, we do FME sales, provide support, training, consultancy and some development for our customers which are mainly in Finland but also in Estonia and Russia. ! Our motto is ”Working should be fun... at least as fun as possible.” with FME it often is! 2
  • 3. Affecto Company Overview 3 Information Management Solutions Karttakeskus GIS business Finland Norway Sweden Denmark Baltic Net sales: 133 M€ in 2013 Approx. 1100 employees
  • 4. GeoArchive GeoArchive has been made by our partner Affecto in Estonia. It manages the whole survey data process aiming that: !  Map and/or network data is "  up-to-date "  accurate "  reliable "  according to rules "  everything you might wish for … 4
  • 5. GeoArchive is meant for ! Local authorities and companies engaged in geodesy ! Gathering and archiving geodetic surveys and distributing map data based on geodetic surveys to users of GeoArchive ! GeoArchive includes processing of: "  geodetic plans "  executive survey drawings (as-built surveys) "  cadastral unit surveys "  data management jobs 5
  • 6. Two implementations in production ! Elion (TeliaSonera in Estonia) "  workflow to manage network updates "  extract-translate-load process "  data model and mapping rules ! City of Tartu "  to manage survey process and data "  workflow to manage map updates "  based on Estonian national standards 6
  • 7. Components of the solution ! Workflow management ! Technical processing "  FME from Safe Software "  Microstation DGN V7 and V8 "  Autodesk DWG 2010 and earlier versions "  mapping rules are held in the database "  validation tests use the same rules ! Filtering approach, only needed data ! Auditing, everything is tracked ! Export on demand into CAD files 7
  • 8. Data flow Input archive Intermediate database Target database Data from field 8 Automatic Semi automatic Bills paid after acceptance Feedback to fix data
  • 9. Database of real world objects ! Managing attribute data and geometries of different classes of objects: "  buildings "  roads (road class, roads, road sections) "  water "  geodetic marks "  networks "  etc. ! Data model is dynamic, all descriptions of object classes are stored in database 9
  • 10. Some common details of the implementations ! Processing of geodetic surveys and some other map data management jobs "  initiation, accepting, rejecting, registration etc. ! Uploading files of geodetic surveys (FME) "  Microstation DGN "  Autodesk DWG ! Validation of uploads files (FME) "  validation rules are based on Estonian legislation "  validation rules are described in FME "  easy to modify for local needs with FME 10
  • 11. More common details of the implementations ! Uploading object geometries from files to database ‘middle layer’ "  objects in the ‘middle layer’ are not visible for all ! Correction of uploaded geometries in GeoArchive UI ! Surveys map data is made public on final acceptance of the survey "  browsing the map (public data) in GeoArchive map window "  downloading surveys uploaded files "  downloading an extract of a map data from specified area (FME) 11
  • 12. An example from the Workbench 12 Accepted data. Colored to separate it clearly. Rejected data. To be sent back with an error report
  • 13. Survey search tool 13
  • 14. Survey information 14
  • 15. Map view (surveys done) 15
  • 16. Map window for editing 16
  • 17. Sample Input 17 Existing Network New Build
  • 18. Benefits ! Increased processing speed, from 3-5 weeks per project to 2-3 days ! Traceability, increased reliability ! Consistency throughout the organisation ! Workload balancing 18
  • 19. Another benefit is a view to multiple data sources 19
  • 20. Lessons Learnt ! Standardisation is the key to success ! Automated quality checks ! Shallow acceptance curve, to put it nicely (normal resistance against anything new…) ! Constant monitoring of the entire process chain ! Bills paid only after documentation has been accepted 20
