OpenStreetMap is a volunteer-built map where roads, paths, buildings and local corrections become open geographic data anyone can use.

Why it matters

The idea in context

Many maps arrive as finished surfaces, but OpenStreetMap is closer to a public notebook that never stops being amended. A footpath, a clinic entrance, a missing bridge or a flood-damaged road can matter urgently to the person on the ground. Open data turns local knowledge into infrastructure.

Türkçe

Aynı kart, başka bir dilde.

OpenStreetMap, haritayı kapalı bir ürün olmaktan çıkarır; yollar, binalar, patikalar ve yerel düzeltmeler gönüllüler eliyle ortak coğrafya bilgisine dönüşür.

Bazı haritalar yukarıdan tamamlanmış gibi iner; OpenStreetMap aşağıdan, sokak sokak düzelir. Bir köy yolu, klinik girişi, selde kapanan köprü ya da resmi sistemlerin kaçırdığı küçük geçit, sahadaki biri için büyük fark yaratabilir. Harita burada yalnız yön bulma aracı değil, yaşayan bir kamusal hafızadır.
