  "description": "What the Bangkok comprehensive plan permits where the tracked projects are being built, grouped by the zone each one falls in: the floor area ratio and open space ratio in force, and how the March 2026 draft plan would change them. Zone assignment is a point-in-polygon query on each project's own coordinates against the city planning department's published layers. FAR and OSR govern the zone, not the plot: setbacks, road-width rules and a project's own EIA conditions apply on top.",
