Researchers have introduced VHR-Bench, a new benchmark suite designed to evaluate foundation models on very high-resolution (VHR) Earth observation imagery. The study found that models pretrained on large natural image collections or specifically on VHR data transfer effectively to VHR tasks, often with complementary strengths. A notable finding is that continuing self-supervised pretraining on VHR tiles can further improve model performance, especially when labeled data is scarce, supporting a "generalize-then-specialize" strategy.
