Drop a pin. Get flood exposure, fire history, drought stress, and heat risk — derived from satellite imagery and 30 years of climate data. Instant results. No GIS skills needed.
What we analyze
5 years of cloud-free satellite passes reveal drought stress trends, canopy loss, fire episode detection, and urban heat signatures — at 10 m resolution, globally.
Radar sees through clouds and at night. Klimex detects chronic inundation and acute flood events at your exact coordinates — not from a flood map drawn in 1996.
Temperature trends, precipitation anomalies, vapor pressure deficit, and drought index. Long-term baselines that put today's risk in historical perspective.
How we analyze
Monthly best-scene composites over a 5-year window. Seven bands read from public COG assets on AWS, masked for cloud and snow via the Scene Classification Layer. Six spectral indices computed per scene: NDVI · NDWI · NDMI · NBR · NDSI · BSI. Aggregated to long-term features: vegetation trend, canopy proxy, fire episode detection, bare soil frequency, and surface water persistence.
VV polarization backscatter read from IW GRD scenes. Water pixels identified by DN threshold calibrated to the sentinel-s1-l1c archive. Flood events detected via an orbit-stratified adaptive threshold (MAD). Snow and steep terrain excluded from water fraction computation. Outputs: chronic inundation frequency, acute flood event count, active flood flag.
Point extraction via OPeNDAP from the University of Idaho THREDDS server. Five variables: tmax · tmin · ppt · vpd · PDSI. Derived features: maximum temperature trend and anomaly, annual precipitation, high-VPD frequency, and drought month frequency. Grid-cell results cached in DuckDB and shared across nearby queries.
Elevation, slope, and terrain relief extracted from the public Copernicus 30 m DEM on S3. Slope used to mask steep pixels from SAR flood detection. Elevation range used in risk scoring as a topographic flood modifier.
All derived features are merged and scored across six climate risk dimensions: drought · wetness · fire · heat mitigation · flood · heat stress. Weights are climate-zone-specific via Köppen classification — a Mediterranean site and a tropical site are not scored the same way. Urban locations receive a canopy-deficit-weighted composite.
