抽象的。本文介绍了一个FlatGeobuf数据库的地理空间分析，该数据库由日本各地约4170万个Mapillary照片拍摄地点的六年地理数据和OpenStreetMap(OSM)的道路数据等地理空间数据组成。尽管Mapillary的记录比OSM短，但它是一个海量数据来源，作为志愿地理信息的新资源，预计未来将引起人们的注意。因此，我们旨在阐明Mapillary用户的地理分布和时间序列变迁，并尝试分析这些道路景观图像与OSM道路数据和当地地理分布特征的关系。虽然地图位置的地理分布是有偏差的，但收集了大量关于当地道路的信息，这可能会提高OSM道路数据的质量，扩大整体道路数据。
Abstract. This paper presents a geospatial analysis of a FlatGeobuf database composed of six years of geographic data on approximately 41.7 million Mapillary photo shooting locations throughout Japan and geospatial data including road data from OpenStreetMap (OSM). Although Mapillary has a shorter track record than OSM, it is a massive data source and its use as a new resource for volunteered geographic information is expected to attract attention in the future. Therefore, we aim to clarify the geographical distribution of Mapillary users and time-series transitions and attempt to analyze the relationships of these road landscape images with OSM road data and the local geographical distribution characteristics. Although the geographical distribution of Mapillary locations is biased, much information is collected for local roads, which may improve the quality of OSM road data and expand the overall road data.
