provides curated datasets at Kick-off. May include road network, geological surveys, historical sinkhole records, and more. We will integrate immediately.
10,000 samples generated from distributions documented in published research. Feature distributions are calibrated to Bangkok conditions (marine clay, monsoon rainfall, subsidence rates from published measurements).
| Feature | Source of Distribution |
|---|---|
| Subsidence rate (0-25 mm/yr) | Wang 2025, Zhang 2024 — Bangkok marine clay rates |
| Rainfall (monsoon pattern) | Thai Meteorological rtment historical data |
| Soil moisture | Open-Meteo ERA5 real measurements |
| Crack density | RDD2022 dataset baseline (85% mAP) |
| Soil type (marine clay index) | DMR geological maps — Bang Kapi formation |
