  • Gis - open source potentials

    1. 1. Cloud and open source GISTim Willoughby, Assistant Director, LGCSB
    2. 2. The Currency of your data• Automating Change Management• Information where and when it is required• Flexible digital delivery• Data Accuracy Improvement• Do you trust your Data enough to share it?
    3. 3. 5 Business DriversThe World has to be • SaaS, IaaS, PaaS, Web 2.0 / 3.0, Peer to Peer on the Cloud • Addressing and Adapting change and to change • Instantaneous, Online Response from Inter-continental companies The World is Flat • Digital Supply Chain across Global companies / across the globe • Environmental ComplianceThe world is green • Reduce your own and your companies Carbon Footprint • Consumers and Workforce - always on - connected anywhereThe World is Mobile • Increased demand and expectation for services The World of Low • Energy and Cost Efficient Computing and Data Centres Cost ICT • Flatter Budgets require Efficiencies CAPX and OPEX
    4. 4. Effective Communication• Clear Messages• Reduce Complexity• Don’t have opinions on everything• Good and Bad News
    5. 5. Security is changing• Security has to be appropriate• Security has to be measured• Can have things so secure that they are unusable.
    6. 6. Cloud / Open is forcing ChangeWith or Without the Owners / Shareholders
    7. 7. So far ICT has not fundamentally changed government • 1990s: lCT expected to make government more transparent, efficient and user oriented • 2005+: disillusion as bureaucracy still in existence • Can Cloud Help?Jane E. Fountain – Gov 1.0 – Just Replicating the Silos on the Internet
    8. 8. Goverment dont always Understand What the people Want?
    9. 9. What governments often Deliver
    10. 10. why is crowd sourcing important? Crowd Source – Group Collaboration is more powerful than individual achievement 1
    11. 11. Typical Individual effortmany hours, one map 2
    12. 12. OpenStreetMap, 2011200,000 contributors, one map 3
    13. 13. why is open source important? "Given enough eyeballs, all bugs are shallow." - Eric S. Raymond, co-founder of the Open Source Initiative 7
    14. 14. why is open source important? free speech
    15. 15. why is open source important? “Think free as in free speech, not free beer.” - Richard Stallman, founder of the Free Software Foundation 10
    16. 16. who uses open source?90% of supercomputers60% of internet servers30% of smart phones 11
    17. 17. What is Cloud?A pool of highlyscalable, abstractedinfrastructure, capable ofhosting end-customerapplications, that is billedby consumption.
    18. 18. What has Cloud ever done for GIS? Apart from Scale, Enterprise Mapping, Open Data, Standards, Google, API’s, Open Street Maps, Map Servers, GIS - More than just Location, Spatial Analysis and wider adoption now possible 20
    19. 19. What do you need for GISHardwareSoftwareDataPeopleTrainingProcesses 13
    20. 20. Or.. Another way HardwareProcesses Software People / Data Training 22
    21. 21. Hardware• Network • Cloud• Computers• Servers 23
    22. 22. Hardware Software• GIS Software • Open Source• Data Software• OS Software• Network Software 24
    23. 23. People /HardwareProcesses Training• Standards • Evolving• Specifications• Guidelines 25
    24. 24. Hardware Data• We have lots • Evolving• GIS – About the Data..• Tools are important, standards more so 26
    25. 25. Why do Government use GIS• Massive demand for timely, relevant information — “picture says a 1000 words”• Support decision making – Provide users with all the information required to make an informed decision. – Ability to integrate vast amounts of data within one View (Mashup) – Exploit visualisation techniques to present information according to user preference (Raster, vector, 3D, tabular etc) – Visualise /identify patterns/trends etc – Personalisation – Mobile 27
    26. 26. The Data Underworld Massive network of services: water, sewage, drains … Need to know asset location for planning and maintenance Many databases, varying accuracy and provenance Context  Ongoing street openings p.a.  Safety!
    27. 27. Its all about where..
    28. 28. GISGeographic Information System • We have come a long way
    29. 29. Or WizardsGIS is nowMainstream
    30. 30. Still need Common Sense
    31. 31. Where we want to be? Have Sharing Can “No CountyHave Data Infrastructure Collaborate Left Behind”
    32. 32. Local Government and Open Source
    33. 33. The World is changing
    34. 34. open source / open data / cloud the fix your street model
    35. 35. mobile apps – the new frontier of local government
    36. 36. Open Source – Pavement - Road Opening Management 39
    37. 37. from: physical, the (qr code), online source, & augmented reality
    38. 38. Social and Multi MediaResponding through innovation
    39. 39. FOSS4G:Free and OpenSourceSoftware forGeospatialOSGEO:The Open SourceGeospatialFoundation All of the products well talk about today are both free and open-source
    40. 40. Open Source SDI Architecture14 March 2008 Open Source Geospatial 45
    41. 41. Why Use Open Source GIS?1. Marketable skills In this ever-changing job market it is a huge benefit to be able to bring a total GIS package to the table2. Supported by huge development & support community Community is very passionate about helping each other but and continually improving software3. Low start-up costs It is now possible to install a complete GIS stack without paying a cent - LEGALLY4. Security Arguably more secure than proprietary software Backed by large development community Bugs are found and fixed quickly
    42. 42. Why Use Open Source GIS? (cont’d)5. Works on all major platforms (Mac, Linux, Windows)6. Complimentary business model vs linear (see next two slides)7. Theres nothing missing Desktop GIS, Spatial Database Storage, Server... Tons of analysis tools (No licensing worries) Community developed add-ons8. Works with existing GIS data Import .shp files, most major formats Export to most major formats ArcSDE now connects to PostGIS (OS Database)9. No file format lock-in10. Did we mention FREE? Potentially save enough money on software to save jobs

    46. 46. PostgreSQL + PostGIS PostgreSQL is a powerful, open source object-relational database system A true spatial database Conforms to Open Geospatial Consortium standards* ArcSDE can connect to it New to ArcGIS Server 9.3 Secure storage for both spatial and non spatial data Column level permissions granularity PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for (GIS), much like ESRIs SDE*The Open Geospatial Consortium, Inc.® (OGC) is a non-profit, international, voluntary consensus standards organization that is leading thedevelopment of standards for geospatial and location based services.
    47. 47. GeoServerOutputs: WMS, WFS, KML, GeoJSON, GeoRSS, more..Share and edit geospatial dataOpen standards allow publishing from any major spatial data sourceincluding: shapefiles, SQL Server, PostGIS, DB2, Oracle, WFS, TIFFImages, MySQLIntegrates with existing APIs (Google, yahoo, etc.)Connects to ArcGIS ServerWMS can be easily added into existing ArcMap .mxds is an open source software server written in Java that allows users to share and editgeospatial data. Designed for interoperability, it publishes data from any major spatial data sourceusing open standards…GeoServer is the reference implementation of the Open Geospatial Consortium(OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a highperformance certified compliant Web Map Service (WMS). GeoServer forms a core component of theGeospatial Web.

    49. 49. OpenLayersJavaScript Library, including APISimilar to Google Maps APIMakes building dynamic mapping webpages VERY easyProvides the tools needed to easily add a map to a webpageAllows overlaying your own dataCan display map tiles and markers loaded from any source OpenLayers makes it easy to put a dynamic map in any webpage. It can display map tiles and markers loaded from any source…OpenLayers is a pure JavaScriptlibrary for displaying map data in most modern web browsers, with no server-side dependencies.OpenLayers implements a (still-developing) JavaScript API for building rich web-based geographicapplications, similar to the Google Maps and MSN Virtual Earth APIs, with one important difference --OpenLayers is Free Software, developed for and by the Open Source software community.
