Abstract
RemoteZero enables geospatial reasoning without box supervision by leveraging semantic verification capabilities of MLLMs for self-evolving localization from unlabeled remote sensing data.
Geospatial reasoningrequires models to resolve complex spatial semantics and user intent into precise target locations for Earth observation. Recent progress has liberated the reasoning path from manual curation, allowing models to generate their own inference chains. Yet a final dependency remains: they are still supervised by human-annotated ground-truth coordinates. This leaves the reasoning process autonomous, but not its spatial endpoint, and prevents trueself-evolutionon abundant unlabeled remote sensing data. To break this bottleneck, we introduce RemoteZero, abox-supervision-freeframework forgeospatial reasoning. RemoteZero is motivated by a simple asymmetry: anMLLMis typically better at verifying whether a region satisfies a query than at directly generating precise coordinates. Leveraging this stronger discriminative ability, RemoteZero replaces geometric supervision with intrinsicsemantic verificationand enablesGRPO trainingwithout box annotations. The resulting framework further supports iterativeself-evolution, allowing the model to improve from unlabeledremote sensing imagerythrough its own verification signal. Experiments show that RemoteZero achieves competitive performance against strong supervised methods, demonstrating the potential of self-verifying training forgeospatial reasoninglocalization.
