The IDEAL-VGI research project is nearing its end. And while that won’t be the end of our research into social data sources, data quality analyses and land-use information, we are happy to announce a major outcome: the version 1 release of the OSM Element Vectorisation Tool (OEV). The tool was first presented to the public at FOSS4G 2022 in Florence but has since received multiple updates and enhancements.
The release is accompanied by a video podcast featuring Prof. Dr. Sven Lautenbach and Moritz Schott. In the video, the researchers provide an introduction to OSM, OSM data quality and the OEV.
The OSM Element Vectorisation Tool (OEV) enables high resolution data insights into the OSM database. Through researchers, corporations, and (mainly) private users and contributors, the OSM ecosystem has grown to encompass a massive set of tools and services that accompany the data and maps themselves. However, many of these tools and services are either general purpose tools to “do something with the data” or specialized tools to “find out a specific thing” rather than a combination of the two. For example, is-osm-uptodate is a fantastic tool to answer the exact question in its name in a data-driven manner. Alternatively, scientific studies often concentrate on a specific region, as seen in comparing OSM to official data in Teheran (Iran).
The tool sets out to overcome these limitations by combining and providing what has so far been divided and conquered. Specifically, the tool creates a multi-faceted data view that is neither limited to a certain region nor to a specific topic. The goal is to enable data enthusiasts, data analysts and machine learners to visualize a multi-dimensional view of the data without the setup of requisite tools, data and services.
OEV computes more than 37 data dimensions and is based on more than 16 scientific studies, with more dimensions and studies planned for future incorporation. Since the presentation of the tool at the FOSS4G conference 2022 in Florence, additional data insights have been added including user specialization and diversity. These two aspects provide information about the professionalism of the objects editors by calculating how experienced the users are with edits on objects of this type (e.g., land-use, buildings or shops). Moreover, the tool has been made more robust and versatile and is now ready for a first official release to the public.
The full list of indicators and their documentation is available in the tools repository. But you can also quickly dive into its usage on our intuitive frontend which provides some precomputed examples.
While we use the tool in our current research and have shown its practicality in the article “OpenStreetMap Element Vectorization- A Tool for High Resolution Data Insights and Its Usability in the Land-Use Land-Cover Domain” published in The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, we will also release a mini-blogpost series over the next few weeks. The posts will present some example use cases of the tool. To access those resource, check out the OEV Examples repository.
The tool can already be used on personal laptops and via the tool’s website, but the team will continue development of OEV in order to launch a fully-fledged OEV service and integrate its functionality into other well-known services provided by GIScience and HeiGIT including OQT and OhsomeHex.
The associated IDEAL-VGI project was part of a DFG Priority Program named VGIScience, which featured a total of 30 projects on the topic in the past 6 years. As many of these project are also set to conclude inthe near term, make sure to read about their results here: VGIscience | VGIscience final colloquium.
