From Wiki Gardening to Map Gardening: Analyzing Contribution Patterns in OpenStreetMap

A session at State of the Map US 2013

Sunday 9th June, 2013

11:00am to 11:30am (PST)

This session will propose a framework for classifying and quantifying the ways in which OpenStreetMap contributors interact with OSM data. Existing research does not differentiate between various types of contribution to OSM, even though these activities (such as adding new features in an unmapped area versus modifying the geometry or tags of existing features) may stem from different motivations, rely on different types of skill, and occur in significantly different contexts. This lack of distinction leaves many questions unanswered. Are the users who initially contribute data the same users who later maintain it? Do the types of tasks undertaken by users change over the duration of their engagement with OSM?

Alan will present an analysis of the extent and frequency of map gardening - the crowd-sourced maintenance of geographic data - within OSM, making comparisons across spatial and temporal scales and between individual users. He’ll argue that this typology offers a new tool for understanding what characteristics lead to committed OSM contributors and healthy local mapping communities.
