Working with satellite data normally means QGIS, coordinate systems, spectral bands and a machine that can open a 10,000 pixel wide image. Most people with real questions about land never get past that wall.

We turned it into a map and a question box. Upload Sentinel-2 archives, click around, ask things in plain English.

I led the team of six and worked on the LoRA fine-tuning, the raster pipeline, the routing layer and the frontend. The fine-tuning was the fun part: we taught an open multimodal model to actually read satellite imagery.

71.26% VQA accuracy and 0.415 BLEU-1, beating several open-source baselines that had far more compute than we did. We finished top five in the country at a national ISRO hackathon.
