Models (SDMs) predict species across space from spatially explicit features.

Our insight is that satellite's earth observation photos are not just images

We perform extensive experiments to confirm the effectiveness of AnyChange for zero-shot change detection.

Thus, instead of simply detecting changed pixels, we want to identify change events. We define a change event as a group of pixels over space and time that are all changed by a single event. Weareinterested indeveloping systems thatcanautomatically detectchangeeventsandassign to each a semantic label that indicates the nature of the event, e.g., forest fires, road construction etc. Identifying change events is a much more challenging problem than change detection.

The proposed algorithm, aswell astheloss function, naturally generalize todifferent topological structures in both 2D and 3D settings.
