Researchers have developed a new structured text representation for generating landmark-based route instructions using large language models (LLMs). This method utilizes SVG format to encode spatial features, maintaining a geometric connection with map images and allowing LLMs direct access to spatial and semantic data. Experiments using a new dataset derived from human-written routes and OpenStreetMap data indicate that this structured text input performs comparably to or better than image-based PNG inputs. Furthermore, fine-tuning smaller, local LLMs on this structured data enables them to achieve high accuracy in landmark selection for navigation. AI
IMPACT This research could lead to more intuitive and efficient navigation systems by enabling LLMs to better understand and utilize spatial map data.
