Urban-Graph: Bridging Local SLAM and Global Earth Observation for Fine-Grained Urban LCLU Mapping
Abstract. Urban scene understanding requires both global geographic context and local structural detail. Earth Observation (EO) imagery supports large-scale land-cover and land-use (LCLU) mapping, but in urban areas it often merges heterogeneous surfaces into broad built-up classes. Vehicle-based sensors such as LiDAR...
