Best use for travel intelligence

For travel decisions, noise mapping is most useful as a confidence-weighted risk model for hotels, neighborhoods, and transport corridors when station coverage is thin.

What this changes for travelers

  • Measured spine: Official stations anchor the map where real observations exist.
  • Complaint overlay: Adds nuisance hotspots and source categories that measurements alone miss.
  • Proxy enrichment: Roads, nightlife, airports, barriers, and industrial zones make hotel and neighborhood predictions more honest.
  • Confidence bands: Prevents the map from pretending a modeled block has the same certainty as a measured station.

Best sources to start with

  • Best measurement spine: PCD Noise4Thai and PCD noise monitor CSV for the official measured backbone.
  • Best source-risk overlay: OSM noise monitoring stations and noise barriers plus airport, road, nightlife, and industrial proxies for context between stations.
  • Best complaint overlay: PCD ECAP for nuisance hotspots and source-type patterns that measured station density alone will miss.
  • Best developer starting point: Build confidence-weighted noise maps that label measured, complaint-derived, and modeled evidence separately.
Official / agency sources

4 of 8 sources look official or agency-backed.

API/feed candidates

5 sources expose API, feed, CKAN/DataStore, JSON, XML, or similar machine-readable access.

Near-real-time signals

1 sources have live, hourly, event-driven, warning, or frequent update language.

Developer note

Combine ambient stations, complaints, barriers, airport context, and source proxies with explicit confidence bands so the system never implies false precision.

Last checked and source confidence

Last checked: 2026-05-11.

Source confidence: This cluster is strongest when several sources describe the same traveler problem from different angles: official context, machine-readable feeds, and slower fallback documentation.

Geospatial and satellite

OSM noise barriers

Geospatial noise-mitigation and modeling layer for wall=noise_barrier and related barrier geometry near roads, rail lines, airports, and settlements.

OpenStreetMap Overpass API and ODbL geospatial data Geospatial and satellite

OSM noise monitoring stations

Geospatial enrichment for man_made=monitoring_station with monitoring:noise tagging, useful for mapping public or private noise-monitoring locations and nearby source context.

NSO environment noise statistics

National Statistical Office environmental-statistics publication with 24-hour average noise tables for Bangkok, vicinity stations, and some provinces, based on official monitoring summaries.

Public e-book and statistical tables Transport

AOT airport noise monitoring

Airports of Thailand public environmental-management page describing environmental governance across all 6 AOT airports plus public complaint and community-contact context for airport-noise and related environmental impacts. Useful as reference and disclosure context, but direct automated fetch behavior can vary and it should not be treated as a stable live measurement feed.
