 # VectorOS Vector 100k SimSat VLM Dataset
 
-VectorOS Vector 100k is a high-fidelity multimodal instruction dataset for fine-tuning vision-language models on population-level vector-borne disease surveillance tasks. It was built for the VectorOS hackathon project and targets `LiquidAI/LFM2.5-VL-450M`.
+VectorOS Vector 100k is a high-fidelity multimodal instruction dataset for fine-tuning vision-language models on geospatial epidemiology tasks. It was built for the VectorOS hackathon project and targets `LiquidAI/LFM2.5-VL-450M`.
 
 The dataset contains **100,000** chat-style examples derived from **10,000** geospatial chips across **30 AOIs**. Every accepted chip has a real SimSat Sentinel-2 true-color view, a real SimSat Sentinel-2 NIR-red-green false-color view, a real Mapbox satellite view, and an aligned open-layer evidence overlay.
