Real scenes, not illustrations
Each tile states its index, place and acquisition date.
Land clearing, Gran Chaco
Cleared cropland reads pale against remaining dry forest. Those rectangles are field boundaries, not artefacts.
Irrigated desert
Centre-pivot fields, Wadi As-Sirhan.

Published, versioned, reproducible
Band maths, cloud-mask classes, scene selection and verdict thresholds — with the known limitations, and which way each one biases the answer.
Two ways in
EUDR screening
Check whether a plot lost canopy after the 31 December 2020 cutoff.
- NDVI, NDMI and NBR must agree before a verdict is issued
- Every result carries scene dates, cloud cover and pixel count
- One plot, or a CSV of up to 1,000
- PDF report you can file alongside a due-diligence statement
Explore satellite data
Draw an area and measure it, anywhere on Earth.
- Vegetation, fire, burn severity, water, drought, land cover
- Build a custom spectral index from any Sentinel-2 bands
- Track an area over time and get alerted when it changes
- Export GeoTIFF, CSV and publication-ready figures
From the blog
The date you picked is probably not the date of your satellite image
Satellites pass on a fixed orbit and most passes over the wet tropics are too cloudy to use, so an image of your plot on your chosen date often does not exist. What every tool does instead is substitute a different one, usually without saying so. We measured how far that goes: up to 104 days.
Read →EUDR: what actually changed in 2026, and who still has to do the work
The Commission has confirmed 30 December 2026 with no further delay, moved the due diligence burden onto whoever first places goods on the EU market, and taken six product categories out of scope. If you import, here is what applies to you and what no longer does.
Read →What satellite burn mapping can and cannot tell you
NBR is the standard way to map fire damage from satellites, and it has four limitations that matter. We measured all of them against Europe's official fire perimeters, and built the corrections into GeoTown. Here are the numbers and what we do about each.
