摘要:
本文介绍了Prithvi-EO-2.0,一种新的地理空间基础模型,相较于其前代Prithvi-EO-1.0有显著改进。该模型在NASA的Harmonized Landsat和Sentinel-2数据档案中训练了420万个全球时间序列样本,分辨率为30米。新模型集成了时间和位置嵌入,以在各种地理空间任务中实现更佳性能。通过与GEO-Bench的广泛基准测试,该模型在一系列任务上比之前的Prithvi-EO模型提升了8%。此外,在不同领域和分辨率(即从0.1米到15米)的遥感任务上,该模型也优于六个其他地理空间基础模型。结果表明,该模型在经典地球观测和高分辨率应用中都表现出多功能性。早期用户和领域专家(SMEs)的参与使模型和数据集设计能够持续反馈,从而在灾害响应、土地覆盖和作物制图以及生态系统动态监测等多样化的SME主导应用中实现定制化。Prithvi-EO-2.0作为开源模型可在Hugging Face和IBM TerraTorch上获得,更多资源在GitHub上。该项目体现了所有参与组织所采用的可信开放科学方法。
英文摘要:
This paper presents Prithvi-EO-2.0, a new geospatial foundation model that offers significant improvements over its predecessor, Prithvi-EO-1.0. Trained on 4.2 million global time series samples from NASA's Harmonized Landsat and Sentinel-2 data archive at 30-m resolution, the new model incorporates temporal and location embeddings for enhanced performance across various geospatial tasks. Through extensive benchmarking with GEO-Bench, the model outperforms the previous Prithvi-EO model by 8% across a range of tasks. It also outperforms six other geospatial foundation models when benchmarked on remote sensing tasks from different domains and resolutions (i.e. from 0.1 m to 15 m). The results demonstrate the versatility of the model in both classical Earth observation and high-resolution applications. Early involvement of end-users and subject matter experts (SMEs) allowed constant feedback on model and dataset design, enabling customization across diverse SME-led applications in disaster response, land cover and crop mapping, and ecosystem dynamics monitoring. Prithvi-EO-2.0 is available as an open-source model on Hugging Face and IBM TerraTorch, with additional resources on GitHub. The project exemplifies the Trusted Open Science approach embraced by all involved organizations.
