havasaha

havasaha ("airspace") is a map of where a drone may and may not fly in Türkiye. It shows the zones the civil aviation authority (SHGM) publishes — no-fly in red, permitted in green — together with temporary NOTAM restrictions, 3D terrain and the sun times for the day, and lets you search more than sixty thousand Turkish place names as you type. There is no account and no fee; it is the planning step I kept doing by hand before every flight for the Dronosfer channel.

The zone geometry is baked, not proxied: a scheduled job pulls the source data, converts it and publishes versioned snapshots and vector tiles to object storage, so a public site never puts its traffic on the authority's own map server, and every reading on the page carries the timestamp of the bake it came from. The app is Svelte 5 with MapLibre on Cloudflare, and shares its planning code with my DJI telemetry player rather than copying it.

It is informational only; the legal source is SHGM, and the page says so on every visit.
