DYAAN — Data You Analyse & Act oN
Draw a rectangle, trace a shape, or snap to a real lake, park or forest — and Dyaan reads the public satellite archives to return measured hectares, detections and change over time. No API keys. No modelled stand-ins. Every figure ships with the bytes it was counted from.
- Any place on EarthDraw, trace or snap to a real feature — anywhere.
- Straight from the satellitesNASA, ESA & Copernicus public archives — keyless.
- Measured, not modelledEvery number counted from real pixels, with the receipts.

Six answers, measured — not modelled.
Each capability is a real read of a public archive. Where a source is silent, Dyaan says so.
💧
Surface-water change
Hectares of water gained, lost and held since 1984, counted pixel by pixel from the JRC Global Surface Water transitions raster at 30 m.
1984–2021 · 30 M🌿
Vegetation & greenness
Sentinel-2 L2A at 10 m: mean NDVI, the vegetated fraction and a water / bare / sparse / moderate / dense split — counted from the real pixels of the least-cloudy scene over your area.
LIVE · SENTINEL-2 L2A NDVI🛰️
Change detection
Pick two years and Dyaan compares the same area across them — the NDVI shift, greening or browning, measured pixel by pixel. Change over time, not a static snapshot.
LIVE · SENTINEL-2 TIME-SERIES✏️
Draw, trace or snap
Drag a rectangle, trace any polygon, or snap the area to a real OpenStreetMap feature — a lake, park, forest or district — and every analysis clips to that exact shape.
NOMINATIM PLACE SEARCH✨
Ask in plain English
Type a question — “how much water has this lake lost since 1984?” — and Dyaan runs the real analysis and answers with measured numbers. It never invents a figure; if it cannot measure something, it says so.
LIVE · GROUNDED AI ASSISTANT🧾
Evidence on every number
Rasters read, tiles fetched, bytes downloaded, pixels counted, timestamps. If an upstream archive is down you get an error, never a filler value.

USE CASES
What people watch with Dyaan.
Every example below runs on the real, keyless data already in the product — pick an area, get measured numbers, and put it on a Watchlist to be alerted when it changes.
🏗️
Dam & reservoir safety
Track a reservoir's water gained and lost since 1984 and the terrain around the wall, and watch the area for month-to-month change — an early read on drawdown, silting or encroachment.
🌲
Deforestation & land use
See tree-cover loss year by year from Hansen Global Forest Change, alongside land cover and NDVI change, to catch forest converting to cropland or built-up before it is on anyone's radar.
🌾
Crop & farm health
Per-field greenness (NDVI), recent rainfall and dry-spell length, and today's weather — import your own field boundary as GeoJSON or KML and every reading clips to that exact shape.
🚨
Wildfire & disaster watch
Active-fire detections, air quality and weather for an area, on a Watchlist that alerts you when new fires appear or the air turns unhealthy — a standing eye on a town, park or asset.
🏙️
Urban growth & encroachment
Watch built-up land expand into farmland or protected areas by comparing land cover over time — useful for planning authorities, utilities and anyone defending a boundary.
🌊
Water stress & flood context
Combine standing-water change, the last weeks of rainfall and low-lying terrain to build fast flood or drought context for a district — measured, not guessed.
Three steps from a rectangle to an answer.
-
01
Draw, trace, or snap to a feature
Drag a rectangle, trace a custom polygon, or type a name to snap to a real lake, park, forest or district. Dyaan validates the area and tells you up front how much raster it will read.
-
02
Dyaan reads the archives
Fire feeds are parsed row by row; surface-water rasters are range-read over HTTPS and LZW-decoded server-side, so a city AOI costs kilobytes, not 23 MB.
-
03
Read measured results
Hectares, detections, megawatts and per-class breakdowns land in the panel and the attribute table — each with the evidence of how it was counted.
