🛰️ Weather Image Analyst Dashboard

Analyse ESA Sentinel-2 satellite imagery for any location. Scenes are fetched from the public AWS Earth Search STAC API.

🟢 rasterio available — real spectral band analysis enabled.

Step 2 — Spectral Band Analysis (Real Pixel Data)

Reads actual Sentinel-2 spectral bands (COG files) and computes vegetation, water, snow and bare soil indices from pixel values.

⚠️ This fetches large GeoTIFF files — may take 1–3 min depending on scene count. Tip: limit scenes with a shorter historical window or tighter cloud filter.

Select Spectral Indices to Compute

NDVI — Vegetation Health NDWI — Water Bodies NDSI — Snow & Ice BSI — Bare Soil

Left panel: true-colour thumbnail. Right panel: computed spectral index map (false colour). Each map shows where the signal is spatially distributed across the scene.
