EarthScape: A Multimodal Dataset for Surficial Geologic Mapping and Earth Surface Analysis

Understand

Surficial geologic (SG) maps are essential for understanding surface processes and supporting infrastructure planning, but current workflows are labor-intensive and difficult to scale.

• We introduce EarthScape, an AI-ready multimodal dataset for SG mapping that integrates digital elevation models, aerial imagery, multi-scale terrain features, and hydrologic and infrastructure vector data within a unified, reproducible pipeline.
• We report baseline benchmarks across single-modality, multi-scale, and multimodal configurations.
• Our experiments show that terrain features provide the most reliable predictive signal, while raw spectral and elevation inputs degrade substantially under cross-region evaluation.
