MaGRoad introduces a fundamental shift from node-centric to path-centric reasoning. Unlike previous methods that rely on sparse endpoint features, MaGRoad’s core module, MaGTopoNet, aggregates multi-scale visual evidence along the entire geodesic path of a candidate edge. This design integrates rich contextual information, making connectivity inference resilient to occlusions, weak textures, and ambiguous junctions prevalent in off-road scenes.
WildRoad is the first large-scale, continent-spanning vectorized benchmark specifically designed for off-road environments. Addressing the prohibitive cost of manual annotation, we developed an AI-driven interactive pipeline that uses iterative bootstrapping and prompt-driven methods to efficiently curate this diverse dataset of 221 high-resolution images (8K×4K, 0.3 m/pixel) covering challenging terrains across six continents.
MaGRoad achieves state-of-the-art performance on the challenging WildRoad benchmark, with the fast version reaching an F1 score of 82.22. Crucially, its path-centric design ensures strong generalization to urban datasets like City-Scale, SpaceNet, and Global-Scale, demonstrating consistent strength in recall. An optimized, unified Non-Maximum Suppression (NMS) strategy for vertex extraction delivers a significant 2.5× inference speedup while maintaining high accuracy, enhancing practical applicability.
The robust and accurate road network maps generated by MaGRoad are critical for numerous real-world applications. These include improving navigation systems in rural and remote areas, supporting autonomous driving in unstructured environments, enhancing disaster response efforts where infrastructure maps are vital, and aiding urban planning initiatives by providing more complete and precise data on less-traveled paths.

Unlocking Connectivity in Challenging Terrains
MaGRoad demonstrates significant breakthroughs in extracting road networks from complex off-road environments. Unlike previous methods that struggle with fragmented graphs and incorrect topologies in scenes with tree cover or ambiguous junctions, MaGRoad's path-centric approach consistently maintains connectivity and accurately infers network structures. This resilience is vital for applications requiring reliable maps in sparsely connected residential areas and unstructured dirt tracks.
