  1. 1. Open Data Portals 9 Solutions and How They Compare
  2. 2. DaleLutz StewartHarper
  3. 3. Why Open Data? And Why Now?
  4. 4. Citizens are demanding access to open data like never before. We want it.
  5. 5. Great advances have been made in technology. Citizens are tech savvy and aware. We have the ability.
  6. 6. Better decisions are being made by the mass population. Benefits are undeniable.
  7. 7. Why does this matter? Build innovations on top of institutes and empower citizens across the globe.
  8. 8. What is Open Data? “Open data and content can be freely used, modified, and shared by anyone for any purpose” opendefinition.org “Open Data is free, public data that can be used to launch commercial and nonprofit ventures, do research, make data-driven decisions, and solve complex problems.” Open Data 500
  9. 9. Open Data Audiences ● Citizens who want to examine the data and answer questions they have. ● Researchers and journalists who want to gather and analyze the data to tell stories. ● Developers who want to use the data to build applications Source: City of Winnipeg
  10. 10. WhoProducesOpenData? All levels of governments Intergovernmental Organizations Non Governmental Organizations Private Companies Academic Institutes
  11. 11. Governments are doing better
  12. 12. PDFs make for poor Open Data spatialityblog.com/2011/08/31/mapping-hurricane-nyc/
  13. 13. NYPD Example Released collision data in PDF Citizen created a PDF Scraper Tool so the data could be read NYPD responded and their data is now on Socrata Limit public interaction
  14. 14. Ingredients for Open Data Portal Success
  15. 15. Updating Datasets should not be static and should be regularly updated.
  16. 16. How to keep your data up-to-date: Provide your data as a published feed (e.g. RSS) or API. Connect your open data platform directly to the master database. Enlist the help of FME to sync your master data store with your open data repository.
  17. 17. Coordinate System Projections (Spatial Data Only)
  18. 18. Projection Support ● Advanced users should be able to choose their projection. ● Local (e.g. State Plane or British National Grid) and global projections should be provided. ● Globally we would recommend: ● WGS 84 Lat/Lng (EPSG: 4326) ● Spherical Mercator (EPSG: 3857)
  19. 19. Ensure Data Quality
  20. 20. Pay Attention To Data Quality ● Ensure you’ve covered off our Data Quality Checklist ○ FME can automate the checking ● Check out csvlint.io -- a free CSV quality checker
  21. 21. Delivery Mechanisms Formats / APIs
  22. 22. Data should be available in... Tabular: ● CSV ● JSON (API) Spatial: ● GeoJSON (API) ● Shapefile Tabular: ● Excel ● XML Spatial: ● AutoCAD DXF/DWG ● Esri File Geodatabase ● GML ● KML ● Mapinfo TAB Suggested: Supplementary:
