志愿地理信息（VGI）的概念是最近在新的Web 2.0技术中出现的。OpenStreetMap项目是目前基于VGI的系统中最重要的例子。它的目标是利用互联网用户的贡献制作免费的矢量地理数据库。在这种免费下载地理数据库的情况下，空间数据质量成为一个关键考虑因素。本文研究了法国开放街道地图数据的质量。它将Haklay的工作扩展到法国，提供了一套更大的空间数据质量元素评估（即几何、属性、语义和时间准确性、逻辑一致性、完整性、谱系和使用），并使用了不同的质量控制方法。研究的结果提出了一些问题，如过程的异质性、生产规模以及对标准化和可接受规格的遵从性。为了提高数据质量，必须在贡献者的自由和他们对规范的尊重之间取得平衡。开发适当的解决方案来提供这种平衡是用户生成内容领域的一个重要研究问题。
The concept of Volunteered Geographic Information (VGI) has recently emerged from the new Web 2.0 technologies. The OpenStreetMap project is currently the most significant example of a system based on VGI. It aims at producing free vector geographic databases using contributions from Internet users. Spatial data quality becomes a key consideration in this context of freely downloadable geographic databases. This article studies the quality of French OpenStreetMap data. It extends the work of Haklay to France, provides a larger set of spatial data quality element assessments (i.e. geometric, attribute, semantic and temporal accuracy, logical consistency, completeness, lineage, and usage), and uses different methods of quality control. The outcome of the study raises questions such as the heterogeneity of processes, scales of production, and the compliance to standardized and accepted specifications. In order to improve data quality, a balance has to be struck between the contributors' freedom and their respect of specifications. The development of appropriate solutions to provide this balance is an important research issue in the domain of user-generated content.
