Evaluation of the Micro-Tasking Method for OpenStreetMap Imports

Abstract

Open Geospatial Data, capable of enriching OpenStreetMap, is being released by governments around the world at an increasing rate. The OSM import methods have been refined since the massive TIGER-import, moving towards assisted methods such as the with micro-tasking method used by the LA and NY buildings imports. While these imports serve as great case studies of imports, they do not deal with complex datasets, or updates to the data, neither do they deal with partitioning of tasks. We examine how the Norwegian FKB-dataset can be imported to OSM using micro-tasking, and perform a user-test to determine the best partition of these micro-tasking tasks. In this we hope to improve the micro-tasking method to enable efficient and correct imports and updates of Open Governmental Geospatial Data to OSM.
