Show HN: Satellite imagery object detection using text prompts

Detect any object in satellite imagery using a text prompt is active in the show hn launch space.

Profile

I built a browser-based tool for detecting objects in satellite imagery using vision-language models (VLMs). You draw a polygon on the map and enter a text prompt such as "swimming pools", "oil tanks", or "buses". The system scans the selected area tile-by-tile and returns detections projected back onto the map as GeoJSON.Pipeline: select area and zoom level, split the region into mercantile tiles, run each tile with the prompt through a VLM, convert predicted bounding boxes to geographic coordinates (WGS84), and render the results back on the map.It works reasonably well for distinct structures in a zero-shot setting. occluded objects are still better handled by specialized detectors like Y

Detect any object in satellite imagery using a text prompt is positioned in show hn launch, a segment that rewards a clear, focused offering.

Directory data places it at the Show HN launch stage.
