Area watch · dated imagery

Your field, dated every day.

Drop a pin. For the field, we keep one frame per acquisition day, choosing Sentinel-2, Landsat, or Sentinel-1 in that order. Around it, a daily 240 km true-colour mosaic and a Meteosat-12 frame every three hours.

The whole record

A season, month by month.

Eleven months over the same field. Each frame is the clearest field pass of its month, with its date and clear share. Weather frames are context, not a substitute for the field.

How it works

One frame a day. Whichever satellite saw it.

No polygon to draw. A coordinate, a radius and a period. The record fills in as the archives are searched.

  1. 01

    Drop a pin

    A coordinate and a radius. No shapefile, no drawing. Two kilometres around a field is enough to start.

  2. 02

    Take the best source

    Sentinel-2 first, Landsat second, Sentinel-1 radar when both optical passes are cloudy. One source is enough for a day.

  3. 03

    Keep the field and the weather

    The first source that qualifies for the field, then the daily mosaics and Meteosat-12 frames around it. The newest detail frame is the cover.

The sources

Four sources. One record.

For the field, one frame per acquisition day, chosen from Sentinel-2, Landsat, or Sentinel-1 in that order, plus the weather around it. Every frame is labelled with its source and width.

  • Sentinel-2

    10 m · 2–3 days

    The first optical source the record checks.

  • Landsat 8/9

    30 m · 8 days

    A second optical attempt when the Sentinel-2 pass is cloudy.

  • Sentinel-1

    10 m radar · 6 days

    Radar. It sees through cloud and at night; brighter ground is rougher.

  • Weather

    250 m–2 km · daily to 3 h

    Daily mosaics at 250–375 m over 240 km, and Meteosat-12 at 2 km over 800 km.

Radar is never used on a day with a clear optical scene. Weather frames are context, not the field: 240 or 800 km wide. MODIS and VIIRS via NASA GIBS; Meteosat via EUMETSAT.

Weather

The weather around the field.

A 240 km daily mosaic shows the weather system. An 800 km Meteosat-12 frame shows it every three hours. Both are context, not the field.

MODIS Terra · 1 Aug 2026 · 240 km wide · 250 m · one per day 240 km
MODIS Terra · 1 Aug 2026 · 240 km wide · 250 m · one per day
Meteosat-12 · 1 Aug 2026 · 12:00 UTC · 800 km wide · 2 km · every three hours 800 km
Meteosat-12 · 1 Aug 2026 · 12:00 UTC · 800 km wide · 2 km · every three hours
Context, not the field
Weather frames are wider than the watch. Each frame states its width.
One mosaic a day, per satellite
Five polar satellites, five daily mosaics, from Terra in the morning to NOAA-21 in the afternoon.
Every three hours
Meteosat-12 is geostationary. It covers the same field day and night, at 00, 03, 06 … UTC.
Only inside the disc
The Meteosat disc covers Europe, Africa, and the Middle East. Outside it, no weather frame is claimed.

In orbit

Thirteen satellites. Every frame says which.

Thirteen satellites in three groups: field detail at 10–30 m, daily mosaics at 250–375 m, and one geostationary weather imager at 2 km.

Detail

  • Sentinel-2A · 2B · 2C

    ESA / Copernicus · 10 m · 2–3 days

    The first optical source.

  • Landsat 8 · 9

    NASA / USGS · 30 m · 8 days

    A second optical source.

  • Sentinel-1C · 1D

    ESA / Copernicus · 10 m radar · 6 days

    Radar, through cloud and at night.

Daily mosaic

  • Terra

    NASA · 250 m · daily

    Morning true colour, 240 km wide.

  • Aqua

    NASA · 250 m · daily

    Afternoon true colour, 240 km wide.

  • Suomi NPP

    NASA / NOAA · 375 m · daily

    VIIRS, the first in the series.

  • NOAA-20

    NOAA · 375 m · daily

    VIIRS, afternoon orbit.

  • NOAA-21

    NOAA · 375 m · daily

    VIIRS, the newest polar pass.

Weather

  • Meteosat-12

    EUMETSAT · 2 km · every 3 h

    A weather frame around the field, 800 km wide.

Every frame names its satellite and its width. Weather frames are labelled as weather.

Limits

What it is not.

Not a tree
10 m is a field, a block, an orchard row. You see the row, not the tree.
Not real time
Sentinel-2 publishes hours to days after capture; radar in about half a day.
Not always a photo
On a closed day the frame is radar, dated and labelled as radar.
Not the same scale
A detail frame is a few kilometres of field. A weather frame is 240 to 800 km around it.
Not unlimited
260 detail frames and 240 weather frames per watch, 36 months. The timeline keeps the newest.
Not a live feed
A weather frame arrives every three hours, and only where the Meteosat disc sees the field.
