![]() The development of appropriate solutions to provide this balance is an important research issue in the domain of user-generated content. In order to improve data quality, a balance has to be struck between the contributors' freedom and their respect of specifications. For teaching GIS students how to use OpenStreetMap to contribute geographic data, I have collected GPS tracks around Paris suburbs (quartier Bussy-St-Georges) using the IphiGeNie. The outcome of the study raises questions such as the heterogeneity of processes, scales of production, and the compliance to standardized and accepted specifications. geometric, attribute, semantic and temporal accuracy, logical consistency, completeness, lineage, and usage), and uses different methods of quality control. Having freely available GPX tracks for cycle routes means people can better plan their journey and avoid wrong turns when following the route. OpenStreetMap emphasizes local knowledge and empowers people across the globe to edit. And since it’s open, you can also help improve quality. Data is available for every country in the world, and in many places, the data quality is excellent. It extends the work of Haklay to France, provides a larger set of spatial data quality element assessments (i.e. OpenStreetMap provides global map data in a unified tagging schema, although there are some local variations. ![]() This article studies the quality of French OpenStreetMap data. Spatial data quality becomes a key consideration in this context of freely downloadable geographic databases. The resulting free map can be viewed and. It aims at producing free vector geographic databases using contributions from Internet users. Volunteers gather location data using GPS, local knowledge, and other free sources of information and upload it. Like iD, you can drag and drop your GPX track file. It provides a useful map for each and every cyclist, no matter the practice. Its a desktop application and allows for significant customization. This example shows a workflow to generate HD map from SD maps with detailed lane information using recorded lane detections and GPS sensor data. However SD maps lack detailed lane information that is essential for navigation in an autonomous system. The OpenStreetMap project is currently the most significant example of a system based on VGI. CyclOSM is a beautiful open cycle map built on top of OpenStreetMap data. You can create real-world scenario using Standard-Definition (SD) map imported from OpenStreetMap®. The concept of Volunteered Geographic Information (VGI) has recently emerged from the new Web 2.0 technologies.
