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 YOLO models.

There is a public demo and no login required. I am mainly interested in feedback on detection quality, performance tradeoffs between VLMs and specialized detectors, and potential real-world use cases.","time":1773042753,"title":"Show HN: Satellite imagery object detection using text prompts","type":"story","url":"https://www.useful-ai-tools.com/tools/satellite-analysis-demo/"}],[46052599,{"by":"pseudolus","descendants":5,"id":46052599,"kids":[46060690,46052801,46053814,46054507,46054238],"score":32,"time":1764116512,"title":"Mass Surveillance Is Powering a New Era of Pretextual Traffic Stops","type":"story","url":"https://reason.com/2025/11/24/mass-surveillance-is-powering-a-new-era-of-pretextual-traffic-stops/"}],[45357693,{"by":"sixhobbits","descendants":622,"id":45357693,"kids":[45360977,45360713,45358585,45359809,45358361,45358482,45358467,45365404,45358059,45364529,45359167,45359625,45360781,45358137,45366221,45359354,45362182,45359255,45358379,45359746,45358798,45361530,45358343,45362793,45358602,45359248,45358235,45359108,45365096,45363327,45365173,45360919,45359560,45358249,45366904,45363073,45377959,45362466,45362954,45361668,45360958,45358668,45358522,45362839,45358931,45359640,45361390,45363643,45358067,45360008,45360426,45361332,45364736,45358562,45363390,45358571,45381515,45361265,45359382,45369836,45358483,45360594,45358818,45395384,45359200,45362231,45361863,45358178,45359689,45369379,45360840,45358728,45360992,45361215],"score":1058,"text":"Previously: Cache of devices capable of crashing cell network is found in NYC - https://news.ycombinator.com/item?id=45345514 - Sept 2025 (283 comments)","time":1758702260,"title":"That Secret Service SIM farm story is bogus","type":"story","url":"https://cybersect.substack.com/p/that-secret-service-sim-farm-story"}],[44639135,{"by":"afeuerstein","descendants":155,"id":44639135,"kids":[44639254,44639238,44639771,44640004,44639750,44640098,44639562,44639168,44639611,44640324,44639325,44639616,44639641,44639599,44648416,44640568,44639467,44644937,44640673,44641036,44644615,44647859,44643853,44641865],"score":162,"time":1753124977,"title":"12ft.io Taken Down","type":"story","url":"https://www.newsmediaalliance.org/takedown-of-12ftio/"}],[43618281,{"by":"seriousoblack","descendants":1,"id":43618281,"kids":[43623279,43623285],"score":2,"text":"I built AISiteGen - an AI platform that transforms ordinary photos into magical Studio Ghibli-style artwork.

Key Features:

Authentic Ghibli-style transformations in seconds

Multiple output variations per generation

Customizable style strength and quality settings

Privacy-focused (images aren't stored)

Affordable alternative to commissioning artists

Why I Built This:\nAs a huge Ghibli fan, I wanted an accessible way to see myself and my surroundings in that magical art style. Existing solutions were either too expensive or didn't capture the Ghibli essence well.

Pricing:

−\n9.99−39.99/month for full access

Would love feedback from the HN community! Especially on:

The quality of the Ghibli-style transformations

The user experience of the generation flow
