About OKO

How OKO came about

OKO builds on the open gods-eye-view project by Bilawal Sidhu (MIT licence) and extends it with Slovak and Central European sources, a clean front map for Ukraine, and modules for gas, shipping chokepoints and the Middle East. It is built on CesiumJS and Google’s photorealistic 3D tiles, loaded directly or through Cesium ion. In Slovakia, Bratislava for example has photorealistic 3D buildings; where they are missing, the Slovak orthophoto map and OpenStreetMap help.

The project is in BETA — layers keep arriving and some things are still changing.

The rules we follow

• Layer sources and licences are shown right in the map; delayed, estimated and derived data are labelled.
• We track objects, infrastructure and events — not people. No face recognition and no tracking of individuals.
• Secret keys to data services stay on the server; only the Google and Cesium ion map tile keys reach the browser.
• We do not republish articles — we show the headline and a link to the original publisher.

How OKO works

Most data are fetched by the OKO server in Slovakia from open sources, kept briefly and passed to your browser — this saves providers’ quotas and keeps secret keys off the web page. The globe and all layers are rendered right in your browser. Short share links are kept for 90 days.

What you need

A modern browser with WebGL is enough — on a computer or a phone. An account is optional and free and lets you save followed flights. You can share the view you are looking at with a short link that has a preview for social networks; front, chokepoint and Middle East scenes also as a card in landscape, portrait or square format.
