1) Area of Interest
Click the map to set Lat/Lon for a point.
Rectangle: first click = Start (SW); second click = End (NE). We auto-fill fields.
2) Mode
3) Data Sources
Appears in Long-term mode.
4) Dates & Aggregation
Scale
Window
Variables
SPI uses precipitation. (SPEI/PDSI need P + PET and are disabled in demo.)
| End date | Window sum (mm) | SPI | Category |
|---|
SPI — line
Precip anomaly (mm) — bars
SPI — boxplot
Drought severity — SPI line with shaded events
Drought events
| # | Start | End | Duration (steps) | Min SPI | Magnitude |

Wavelet summary (auto-generated from numeric results)
Wavelet text will appear here after running SPI.
Wavelet scalogram (power vs time & period)
The horizontal axis is the Time Index, and the vertical axis is the Scale Index (Period) in SPI time steps. The color intensity represents wavelet power: Blue indicates low power/weak periodicity, and Yellow indicates high power/strong periodicity.
Global wavelet spectrum (SPI)
SPI–precipitation coherence vs period
Select a chart for AI interpretation
Choose which chart you want the AI to describe. You can visually inspect the chart in its own tab (Charts or Wavelet) and then return here to request an expert interpretation. The AI will use both the selected chart image and the SPI metadata (index type, location, dates).
