Problem statement• It is a simple reality that most developing
countries do not have basic local data about where schools or hospitals are located.

Assumption of solution• We could use wisdom of crowd to correct
existing datasets.
![Page 9: Points of Knowledge](https://reader035.fdocuments.net/reader035/viewer/2022062705/556a15ddd8b42af0198b5005/html5/thumbnails/9.jpg)
Points of Knowledge tool• The basic idea is to incentivize users to verify
data points on based on satellite images and if wrong, move them to another place.

Logic of PoK
• If multiple users move the same point to an approximately same new location the tool calculates a new consensus location.

Future of the tool
• Support of polylines and polygons• Multi-language interface• Allow picture-uploading• GPS position collection using mobile device• Community built on Points of Knowledge• Users communications

Challenge 1
• What is the best country to deploy this tool?
• Could we create a tool to search publicly available authoritative datasets?
![Page 16: Points of Knowledge](https://reader035.fdocuments.net/reader035/viewer/2022062705/556a15ddd8b42af0198b5005/html5/thumbnails/16.jpg)
Challenge 2
• What data exist and what is an accuracy of this data?
• Could we create a tool/methodology for automatic evaluation of available datasets locally and around the world?
![Page 17: Points of Knowledge](https://reader035.fdocuments.net/reader035/viewer/2022062705/556a15ddd8b42af0198b5005/html5/thumbnails/17.jpg)
Conclusion
• The PoK tool was created to solve a problem of a lack of basic data on social infrastructure.
Questions to you: • Could we create a tool to search publicly
available authoritative datasets? • Could we create a tool/methodology for
automatic evaluation of available datasets locally and around the world?
