Using the history of OSM for quality assessment

A session at State of the Map 2013

  • Christopher Barron

Saturday 7th September, 2013

11:45am to 12:05pm (GMT)

Christopher Barron
For the purpose of data quality evaluation OSM is almost always compared with reference datasets. However, these datasets are not always accessible due to the lack of availability, contradictory licensing restrictions or high procurement costs. An OSM-Full- History Dump can serve as an alternative source for quality evaluations. Using so-called intrinsic indicators the quality of OSM datasets can be assessed with the help of the data's history. We will present why and how the history of OSM objects matter and which tools were used. For this purpose, examples for selected cities around the world are analysed and compared with each other to reveal differences in terms of OSM data quality based on the history of the dataset's objects.
