17. 09 August 2015 © ifgi 17 Academic vs. commercial SDI case study search for suitable data: meta data: SCOTS: ISO 19115 (core) COTS: FGDC / ISO minimal capacities to pay attention on automatic mapping required leads to a simplified and adapted meta data subset (based on ISO 19115)

18. 09 August 2015 © ifgi 18 Academic vs. commercial SDI Catalog responses and needs in class Response: URI of a shape file Exploring capacities No standardized way to feed a shape file to a WMS

19. 09 August 2015 © ifgi 19 Academic vs. commercial SDI data access WFS: usability of GML encoded data Visualization aspects how to visualize arbitrary data? WMS -SLD a first solution Map manipulation? SMS = discussion paper  follow every spec?

20. 09 August 2015 © ifgi 20 Academic vs. commercial SDI data processing COTS: lots of processing functionality SCOTS?  web based GIS?

21. 09 August 2015 © ifgi 21 Summary I Turnover rates at universities ArcIMS: 300+ pages manual Continuity necessary Financial aspects Commercial model conceivable: Self-financing by participating universities Integration of new technologies

22. 09 August 2015 © ifgi 22 Summary II Standardized infrastructures do not fulfill the daily needs entirely COTS products still needed New services allow integration of simulation models into SDIs SDI main role: Data acquisition Things will change when more processing capacity will be available as services
