Claims

C1strongest claim

We introduce ELDOR, a large-scale UAV benchmark for monitoring environmental and landscape disturbance from illegal gold mining in the rainforest. ELDOR contains manually annotated orthomosaic imagery covering over 2,500 hectares, with pixel-level semantic labels for both mining-related activities and surrounding ecological structures.

C2weakest assumption

That the manual pixel-level annotations on the UAV orthomosaics provide accurate and consistent ground truth for both mining activities and ecological structures across the full 2,500 hectares, which is required for the benchmark tasks and performance comparisons to be meaningful.

C3one line summary

Introduces the ELDOR UAV dataset and four benchmark tasks for semantic segmentation and classification of mining disturbances and ecological recovery in rainforest imagery.
