       Show HN: Detect any object in satellite imagery using a text prompt
        
       I built a browser-based tool that uses Vision-Language Models
       (VLMs) to detect objects in satellite imagery via natural language
       prompts. Draw a polygon on the map, type what you want to find
       (e.g., "swimming pools," "oil tanks," "solar panels"), and the
       system scans tile-by-tile, projecting bounding boxes back onto the
       globe as GeoJSON.  The pipeline: pick zoom level + prompt - slice
       map into mercantile tiles - feed each tile + prompt to VLM - create
       bounding boxes - project to WGS84 coordinates - render on map.  No
       login required for the demo. Works well for distinct structures
       zero-shot; struggles with dense/occluded objects where narrow YOLO
       models still win.
