Journal Article
Du, H., Alechina, N., Jackson, M., & Hart, G. (2016). A method for matching crowd-sourced and authoritative geospatial data. Transactions in GIS, 21(2), 406-427. https://doi.org/10.1111/tgis.12210

A method for matching crowd-sourced and authoritative geospatial data is presented. A level of tolerance is defined as an input parameter as some difference in the geometry representation of a spatial object is to be expected. The method generates ma...

Using qualitative spatial logic for validating crowd-sourced geospatial data (2015)
Conference Proceeding
Du, H., Nguyen, H. H., Alechina, N., Logan, B., Jackson, M., & Goodwin, J. (2015). Using qualitative spatial logic for validating crowd-sourced geospatial data.

We describe a tool, MatchMaps, that generates sameAs and partOf matches between spatial objects (such as shops, shopping centres, etc.) in crowd-sourced and authoritative geospatial datasets. MatchMaps uses reasoning in qualitative spatial logic, des... Read More about Using qualitative spatial logic for validating crowd-sourced geospatial data.
