  1. Spatial Data Infrastructure Feedback on exercise data

  2. 1. Which SDIs did you choose?

  3. 2. Which datasets did you choose?

  4. 3. Could you easily locate and obtain the datasets you needed?

  5. 5. Process of obtaining data…

  6. … and using in ArcGIS online Uploading to ArcGIS online • Sometimes difficult due to ArcGIS online dataset size restrictions • Map services quiet easy to use

  7. 6. Which step was the most difficult? • Metadata miss the information about download • Getting the actual data (problems with download) • Language problems, local languages • The choice of right search terms • Need to log in first- in some cases you have to pay for obtaining larger datasets • Download link difficult to find

  8. 7. Propose the solution to the problems • Provide link to data without registration needed • Make user- friendly geoportals (Simplify geoportals reduce the linked websites for obtaining the data) • Comparison of the metadata results • Use also English as a common language

  9. Most of the data possible to obtain !!

  10. Is it possible to upload datasets? “After searching through both geoportals, I have to conclude that this is not possible. This probably works in the way that governmental entities and private companies have agreements on who provides what data..” “I could not find how it works. However I found out you need to get a (free) account and you will be able to upload the metadata from your own organization.” “The users can upload their dataset using shared visualization column in community page, but they need to log in first because the page is restricted. The users also need to log in if they want to suggest new dataset and share their experiences using the dataset from this portal.

  11. Summary • In most cases the data can be obtained • The most difficult is to find location with link to real data • Available map services instead of real data • Netherland and New Zealand are the most user friendly NSDIs

  12. Thank you for your attention
