• Multiple sizes are created

21. Moderation
• Photo cannot be viewed until it has
been moderated by N people
• Moderators chosen by the system,
can’t ask your friends
• Moderators verify that image is valid
and blur out sensitive parts

24. After Moderation
• Photo becomes part of the main
database
• Anyone can view it whether a
member of OpenStreetView or not

25. Extracting Data
• Images can be tagged with
key=value pairs
• Tags can apply to an area of the
image or the whole image
• Can also mark an image as “unsafe”
to be moderated again

28. Extracting Data
• Moderated images would be
available for people to download
• Teams working on computer vision
projects could use OpenStreetView
as a source dataset

29. API
• Upload images for processing
• Tagging images that have been
moderated
• Marking images as unsafe
• Cannot moderate images through
third party sites

30. API
• Search for images by bounding box
and tags
• Download information and
metadata for images
• Download resized and original sized
images

31. License

36. Current Status
• Can upload already georeferenced
photos and have them moderated
• Photos show up on the homepage

• Can download information on all
images in bounding box as KML
