Sources & method
How we know what we say
The linked source is the authority. This atlas is a dated snapshot, last reviewed October 10, 2026, that separates plans, forecasts and launches.
Bounded checks of selected original public sources and targeted searches for every listed place. This is not a complete recrawl of all citations or all municipalities. A failed fetch is not proof of absence; successful retrieval is not an independent performance audit.
