  1. Finnish experience with OS - The Finnish national geoportal ECA E-Learning Session 21.6.2011 Esa Tiainen, National Land Survey of Finland Based on presentation Exploring new ways to build a Geoportal – case Finnish Geoportalby Jani Kylmäaho, National Land Survey of Finland, in INSPIRE conference 2010, 23rd June, 2010 NATIONAL LAND SURVEY – DOWN TO EARTH

  2. Contents • Finnish National Geoportal – Paikkatietoikkuna.fi • Pilot stage of the Geoportal –traditional developing project approach • Problems with the traditional approach • The Agile Way – how to adopt Open Source • The lessons learned NATIONAL LAND SURVEY – DOWN TO EARTH

  3. Paikkatietoikkuna • National geoportal • INSPIRE Discovery Service + User interfaces for View, Download, Transformation and Registry Services • Pilot version released July 2009 • Improvements during 2009, totalling 1 year for the pilot • Open Source implementation • Liferay, Openlayers, ExtJS, GeoExt, PostgreSQL/PostGIS, GeoNetwork, GeoServer • Free distribution of source code • http://www.paikkatietoikkuna.fi/web/fi/avoin-lahdekoodi

  4. Pilot stage of the Geoportal – the traditional approach • The Finnish Geoportal pilot was built during 2009 using a traditional requirement-based process • Based completely on Open Source software: • Partner surveys and analysis of what functionality is needed were made • Detailed requirements specification was written • A bidding process was started and a consultancy company contracted to deliver the defined Geoportal • The definitions were handed over to the consultant NATIONAL LAND SURVEY – DOWN TO EARTH

  5. Problems with the traditional- 1 • Partner surveys and analysis of what functionality is needed? • It was not possible to capture all requirements at the same time despite of repeated surveys and analysis • Detailed requirements specifications? • It proved nearly impossible to write an accurate requirements specification for the entire duration of the project NATIONAL LAND SURVEY – DOWN TO EARTH

  6. Problems with the traditional- 2 • Bidding process and consultancy company selection for delivery? • The competence of the consultant was assessed mostly based on references and the project plan provided • Definitions handover? • It was not properly ensured, that the consultant and the customer share a common understanding of the expected results NATIONAL LAND SURVEY – DOWN TO EARTH

  7. Problems with the traditional- 3 • Results • Despite the communication during the development process • Resulted functionality not according to specifications • Some specifications had been misinterpreted • Difficult to control the overall quality • ..and as a final Bonus: • The agreement with the consultant somewhat limited the usage of the OS code developed General dissatisfaction and piles of unnecessarywork.. NATIONAL LAND SURVEY – DOWN TO EARTH

  8. Conclusion - The Agile Way • ChooseAgilemethods* for development (scrum) • Payattention to the biddingprocedure • Involve the partners in the process • Fullyexploit the benefits of OpenSource *http://en.wikipedia.org/wiki/Agile_software_development NATIONAL LAND SURVEY – DOWN TO EARTH

  13. The Agile Way - 1 • Choose Agile methods for development • Task Definitions are written in form of a Product Backlog which evolves throughout the entire project • Results are demonstrated after each sprint – new functionality e.g. every 2 weeks • Continuous testing - mistakes or wrong choices you make will show up soon • The priorisation process ensures that the critical and most cost-beneficial functionality is implemented first (80/20 rule) • Control of the project through constant progress monitoring NATIONAL LAND SURVEY – DOWN TO EARTH

  14. The Agile Way - 2 • Pay attention to the bidding procedure • Identify the key competences required for producing the outcome • Evaluate the competence of candidate developers – actually you hire the resources for software development • Developers willingness to current developments - OS software is constantly developing • Consider having the programmers work at/nearby your location (hired resource) NATIONAL LAND SURVEY – DOWN TO EARTH

  15. The Agile Way - 3 • Involve the partners in the process • Gather user requirements constantly • Use your partners as testers • Make it a joint venture ”This is our common Geoportal” • Create Win-Win benefits ”If you open your View Service, I’ll provide you with an embedded map service” • Make sure partners see the benefits they will get – continuous communication NATIONAL LAND SURVEY – DOWN TO EARTH

  16. The Agile Way - 4 • Fully exploit the benefits of Open Source • Ensure liberal licensing policy in the consultancy agreement • Distribute your source code – ”Code developed using public funds should be public”! • Contribute to the OS community (establish own OS group as necessary) for sustainablity • Seek joint projects with organisations with similar needs for developing new features • Utilize common components and platforms NATIONAL LAND SURVEY – DOWN TO EARTH

  17. The outcome • Good quality • Time and effort not wasted due to continuous testing, regular ”checkpoints” and releases • Benefits to the whole SDI in form of • Readily applicable OS components • Accelerated Network Service availability • Cost savings, efficient use of Public Sector data and money • Satisfied partners, management AND developers NATIONAL LAND SURVEY – DOWN TO EARTH

  18. ..But don’t forget to: • Make sure the overall goal (Vision) is crystal clear • Plan the architecture in advance • Choose technologies and development principles • Allocate resources for User interface and Usability desing as well as continuous testing • Use collaborative & communications tools, such as Wiki, Jira, Skype… • Allocate enough time for project management, especially for Product Backlog maintenance • Commit yourself and others to the project! NATIONAL LAND SURVEY – DOWN TO EARTH

  19. OS-components used in geoportal • Liferay – publishing system • OpenLayers – user interface for maps • Geoserver – storage of spatial datasets and maps (+ GeoTools-library application) • PostgreSQL/PostGIS - database server, iBATIS SQL-library • ExtJS – interactive internet (browser) applications • GeoExt – geospatial extentions on Openlayers with ExtJS (capabilities on WMS, WFS) • GeoNetwork – store, manage, and show metadata for datasets and services - discovery service • GeoWeb-Cache for maptiling • Atlassian-tools to support scrum management - Currently EUPL and MIT license; previously (GNU) GPL 3.0: http://www.paikkatietoikkuna.fi/web/fi/ohjelmistokomponentit

  20. More OS sources to apply, e.g.: • http://wiki.osgeo.org/wiki • http://www.geomajas.org/ • http://community.esdi-humboldt.eu/ • The HUMBOLDT GeoModel Editor, which you can use to develop rich Conceptual Models for your geodata. • The HUMBOLDT Alignment Editor, an application that helps you map and transform complex database and application schemas • The Workflow Design and Construction Service, a web service that delivers executable geoprocessing workflows for data harmonisation • The Conceptual Schema Translation Service, a Web Processing Service for transforming data from one application schema to another • The Edge Matching Service, a WPS that deals with inconsistencies in geometry

  21. Thank you for your interest!
