  • 41. SDI – BEYOND PORTALS Enable data upload (gml, Kml, shp, tiff, ...) Allow editing, either through a browser or desktop clients using standards (WFS-T) Implement feedback mechanisms  Commenting, tagging, rating Implement filtering, ranking and other mechanisms to determine fitness for use (most-viewed, most linked to, etc.) Derive metadata from users actions and use © Department of Geo-information Processing (GIP) – 27-Oct-2011 – 45
  • 42. CONCLUSIONS What defines success in a SDI in the year 2020, and how to get there?  What do 2015 SDIs achieve?  What should 2030 SDIs achieve?  What is the pathway from 2015 to 2030?  Which are the critical success factors to get there? © Department of Geo-information Processing (GIP) – 27-Oct-2011 – 46
