Researchers have developed a novel method called Code-as-City that uses a multimodal large language model (MLLM) to extract detailed urban layouts from remote-sensing images. This approach moves beyond simple detection boxes or masks to generate executable code representing city structures, including roads, land cover, and buildings. The generated code allows for the creation of renderable 3D city layouts and synchronized 2D projections, which were evaluated on the CityLayout-100 dataset, achieving significant intersection-over-union scores.
