Research on geospatial foundation models (GFMs) has become a trending topic in artificial intelligence (AI) research due to their potential for achieving high generalizability and domain adaptability, reducing model training costs individual researchers. Unlike large language models, such as ChatGPT, constructing visual image analysis, particularly remote sensing, encountered significant challenges formulating diverse vision tasks into general problem framework. This paper evaluates the recently released NASA-IBM GFM Prithvi its predictive performance high-level analysis across multiple benchmark datasets. was selected because it is one of first open-source GFMs trained time-series high-resolution sensing imagery. A series experiments were designed assess Prithvi's compared other pre-trained task-specific AI analysis. New strategies, including band adaptation, multi-scale feature generation, fine-tuning techniques, are introduced integrated an pipeline enhance adaptation capability improve performance. In-depth analyses reveal strengths weaknesses, offering insights both improving developing future tasks.
