Learning to Reason over Multi-Granularity Knowledge Graph for Zero-shot Urban Land-Use Mapping

This project provides the datasets required for the mKGR paper, including the original spatial vector files and the constructed knowledge graph files. You can directly download KnowledgeGraph.zip for training and validation, or download OriShapefile.zip to build the MKG from scratch. Additionally, we provide two products generated by mKGR for the entirety of China: ChinaLandUse.gpkg and China15min.gpkg, which are the land-use map products of China and the 15-minute city walkability products of China, respectively.
