24 alternatives to Sightline – Shodan-style search for real-world infra using OSM Data

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…

Sightline is a search engine for real-world infrastructure that works like Shodan but for physical locations. Built on OpenStreetMap data, it lets users find telecom towers, power plants, data centers, and other… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    We're Tom and Ryan and we teamed up to build an algorithm with Rust and SIMD to exhaustively search for the longest line of sight on the planet. We can confirm that a previously speculated view between Pik Dankova in Kyrgyzstan and the Hindu Kush in China is indeed the longest, at 530km. We go into all the details at https://alltheviews.world And there's an interactive map with over 1 billion longest lines, covering the whole world at https://map.alltheviews.world Just click on any point and it'll load its longest line of sight. Some of you may remember Tom's post[1] from…

    Hi HN! I'm Jonathan and I built Hacker Search (https://hackersearch.net), a semantic search engine for Hacker News. Type a keyword or a description of what you're interested in, and you'll get top links from HN surfaced to you along with brief summaries. Unlike HN's otherwise very valuable search feature, Hacker Search doesn't require you to get your keywords exactly right. That's achieved by leveraging OpenAI's latest embedding models alongside more traditional indexes extracted from the scraped and cleaned up contents of the links. I think there are many more interesting things…

    Hi HN, I am Anubhav from Ramanlabs. We have been working on a native gui application to allow users to search any video data( mp4, mkv) or video streams (http/rtsp) using computer vision. Application is supposed to work like a video player which displays decoded frames and recognizes objects concurrently, making it an interactive experience. It works in super real-time and only expects a quad-core CPU with AVX2 instructions at minimum. Application is free to download (without any signup/account). We are only supporting WINDOWS for now [0]. Even though this is a binary application,…

    Hey HN, jvaclavik here from OpenClimbing team! We are thrilled to release version 2.0 of our fully opensource/opendata climbing guide. Based on OpenStreetMap for map-data and Wikimedia Commons for images, we created a (hopefully) user-friendly app which completely uses these open databases, thus contributing data back to commons. We designed a simple and powerful notation for drawing climbing routes directly over the Wikimedia pictures: - https://wiki.openstreetmap.org/wiki/Key:wikimedia_commons:pa...
