EUDR plot viewer: 2020 vs now

Load a plot file or draw a plot, then step through every plot: a July–December 2020 Sentinel-2 composite, from before the EUDR cutoff of 31 December 2020, beside a composite of the latest six months, with a divider to drag. It only shows imagery: your team reviews it.

Questions

How it works

  1. Drop your plot file (GeoJSON, KML, KMZ or shapefile) onto the map, draw a plot, or try the sample plots.
  2. The first plot opens with the July–December 2020 composite on the left and the latest six months on the right. Drag the divider across the plot to compare.
  3. Step to the next plot with the arrows or pick one from the list, and note which plots you want to look at more closely.

Input and output

Input
A GeoJSON, KML, KMZ or shapefile with plot polygons or points, or plots drawn on the map.
Output
Each plot on the map, one at a time, with a swipe between a Sentinel-2 composite of July–December 2020 and one of the latest six months.

Example: input

sample-plots.geojson, the sample on the page: three properties from our demo account.

Example: output

Plot 1 of 3 · 32.25 ha
Plot 2 of 3 · 28.13 ha
Plot 3 of 3 · 79.04 ha
Each plot: Sentinel-2 composite of 1 Jul – 31 Dec 2020 left of the divider, a composite of the latest 6 months right of it

Limits

  • It only shows imagery. It doesn't check for deforestation, give a verdict or a score, or tell you whether a plot meets the EUDR.
  • The pictures are Copernicus Sentinel-2 at 10 m a pixel, coarser than Google Earth: a 1 ha plot is about 10 by 10 pixels, so single trees and small clearings do not show.
  • Each picture blends the cloud-free pixels of six months, so very cloudy places can keep haze or gaps, and a dry season can look like lost trees.
  • A point plot has no boundary; the viewer marks the point with a small ring.

Based on the official EU texts. See our EUDR sources, with the version we follow and the day we last checked each one.

Does this tool tell me if a plot is deforestation-free?

No. It only puts two satellite pictures side by side: one from the last six months of 2020, before the EUDR cutoff of 31 December 2020, and one from the last six months. It doesn't detect forest loss, score plots or decide whether they meet the regulation. You look at each plot and decide what needs a closer check.

Where do the satellite pictures come from?

From the Copernicus Sentinel-2 satellites of the European Union, at 10 m a pixel. Each picture blends the cloud-free pixels the satellites recorded over six months. Sentinel-2 is free and covers the whole world every few days, but it is coarser than the high-resolution imagery in Google Earth.

Is my plot file uploaded anywhere?

No. The file is read in your browser and never leaves your computer. To draw the pictures, the map asks for satellite tiles of the area you are looking at, as any online map does.
