Description
Hi HN,I built *Sightline*, a Shodan-style search engine for *physical-world infrastructure*.Shodan makes it easy to explore exposed internet services. Sightline applies the same idea to the real world, using OpenStreetMap as the data source.You can search things like:* “telecom towers in karnataka” * “power plants near mumbai” * “data centers in paris france”or use structured queries:* `type:telecom operator:airtel region:karnataka` * `type:data_center operator:google`Sightline:* uses Overpass API for querying OSM features * uses Nominatim for resolving countries, regions, and cities * avoids hardcoded geography * uses deterministic, rule-based parsing (no AI inference)Repo: https://github.com/ni5arga/sightline Try it out: https://sightline-maps.vercel.app

Could you build this?
Partial A web UI translating queries into Overpass API queries is easy to vibe code, but handling large-scale geospatial indexing and sub-second global queries across hundreds of gigabytes of OpenStreetMap data requires specialized GIS infrastructure.
What it would actually take: A production version requires an ETL pipeline converting OSM planet files (using tools like Osmosis or osmium) into a specialized spatial database like PostGIS or Elasticsearch/OpenSearch with geospatial indexes. The difficult parts include managing high-throughput spatial query parsing, geospatial polygon containment queries, and caching infrastructure to avoid overloading public Overpass endpoints.
