Abstract
As a form of user-generated Volunteered Geographic Information (VGI), OpenStreetMap (OSM) data quality and completeness are related to the characteristics of its contributors. This study investigates the relationship between OSM contributors’ level of activity (i.e. number of updates) and degree of concentration of contributions in one locality. We calculate the proportion of local to total (global) updates, which we term the Local Update Ratio (LUR), for OSM contributors making updates to features in Beijing, New York City, and Berlin between 2008 and 2017. The results indicate that, generally across all three cities, non-active contributors tend to update more locally as compared to active contributors. Among more active contributors, a greater level of activity is associated with a greater proportion of local updates in Berlin and New York City, but not in Beijing, which is likely due to the greater number and experience of OSM contributors in Europe and the U.S. as compared to China.
