Open Tool Maps Infrastructure
- An open-source GitHub repo called 'sightline' was shared as a tool for mapping real-world infrastructure during planning. - The social post suggested the OSINT tool helps visualise assets, routes, and site footprints for early project analysis. - These mapping tools can accelerate feasibility work, but mapped outputs still need field validation before procurement decisions.

A GitHub project called Sightline is turning public map data into a search tool for power plants, ports, telecom towers, hospitals and other physical infrastructure. (github.com) The repository, published by GitHub user ni5arga, describes Sightline as a geospatial intelligence platform built on OpenStreetMap data, with more than 200 searchable infrastructure types across 30-plus categories. GitHub showed 307 stars and 40 forks when the repository was indexed this month. (github.com) The app uses Nominatim to turn place names into coordinates, Overpass API to pull matching map objects, and Leaflet.js to display results on an interactive map. The developer said in a February 2026 FOSS United post that it runs on public OpenStreetMap data, requires no private datasets or API keys, and can be deployed on Vercel. (github.com) (forum.fossunited.org) (nominatim.org) (wiki.openstreetmap.org) OpenStreetMap is a free, editable map of the world built by contributors, and Overpass is the query layer that lets users pull selected pieces of that data instead of downloading the whole map. That makes tools like Sightline useful for early desk research, where planners or investigators want a first pass on what assets sit inside a corridor, site boundary, or city. (openstreetmap.org) (wiki.openstreetmap.org) That also sets the limit. OpenStreetMap coverage depends on volunteer mapping, and the Overpass documentation says the service is optimized for data consumers pulling selected elements, not for ground-truthing whether every object is current, complete, or correctly tagged. (openstreetmap.org) (wiki.openstreetmap.org) Sightline’s own examples focus on discovery: data centers, dams, airports, military bases, pipelines, warehouses and surveillance cameras shown as lists and map points. The project’s architecture diagram also shows a cache layer and a natural-language-style parser, which suggests the tool is designed to speed up search rather than replace site surveys or engineering review. (github.com) (forum.fossunited.org) That puts Sightline in the same lane as other open-source intelligence tools that organize public information into something easier to scan. The difference is that its raw material is map data about real-world assets, so the output can help frame feasibility work, route studies, and footprint checks before teams spend money on field visits. (github.com 1) (github.com 2) The practical takeaway is simple: Sightline can show what public map data says is on the ground, and it can do that quickly. Any procurement, security, or construction decision still needs confirmation outside the browser. (github.com) (openstreetmap.org)
