Zones you can explain.
When a grower asks why that corner got its own zone, you have a real answer: the imagery, the years it's performed, or the shape of the ground. Not a map you're taking on faith.
Nothing to install. Sentinel-2 public imagery back to 2015, included with membership.
The questions change. The evidence doesn’t.
Why is that end always behind? Is this one worth splitting at all? Which acres do we sample? How many did the storm take? Different field, different question — and the answer comes off one of three things every time: the seasons on record, the lay of the ground, or what the satellite saw this week.
-
Because it's run below the rest of the field most seasons. That's the pattern, not one bad year.
Performance Zones compares every part of the field with the field average across the seasons on record, graded on the same scale on every field, so Below Average means the same thing on every farm. One odd season can't drag the lines on its own, and a uniform field can honestly come back as one or two zones.

Because it's the low ground. Water sits there, and the knoll beside it dries out first.
Elevation loads on its own for fields in the US and Canada wherever public LiDAR covers them, or you supply RTK-quality points. Landscape Response reads the whole field's position, high, low and slope, against how each spot has performed. Or refine one poor zone into its wetter and drier halves and preview the split before anything changes.

Because here's the field the day after the hail, next to the week before.
In-Season pulls fresh satellite scenes for a field whenever it needs a look, and after a flood, hail or drought it puts a severity call on every acre with a report ready for the grower or the adjuster.

Behind all three is the same clean picture of the field. Each season's value for a spot is the greenest clear look the satellite got that summer, with cloud, haze and snow screened out first, so the peak that gets used is the crop, not the weather.
The map is allowed to say no.
Performance Zones grades every part of the field on the same fixed scale, season after season. A field that performs alike doesn't get forced into five colors just to give you something to look at — it comes back in one near-average band, and the result says so in plain words: "Most of this field performs alike. Only small areas stand apart from the field average."
Under the result, the zone history shows how often each zone repeated — how often it stayed clearly below, near, or above the field average across the seasons on record. A zone that repeats season after season has earned its place on the map. One that doesn't is called out, in the same plain words.
From field boundary to finished zone map.
Draw the boundary
Draw it or upload it, and TerraZoner pulls the imagery for that field automatically.
Pick a method
Run one-click Performance Zones once you've got the seasons for it, pick the method and count yourself with Composite Zones, or bring in terrain where the ground earns a say. Any of them can be merged down to the count the job needs.

Performance Zones grades on the same fixed scale every time, so a field that performs alike comes back in one band instead of five. The zone history under the result shows how often each zone repeated across the seasons on record.
Tidy it and use it
Fix the odd stray zone by hand, then export the shapefile, a rate map, or take the KMZ into the field on a phone.
Everything on every membership. No per-acre charges, ever.
Every zone method, the terrain tools, In-Season with damage estimates, and every export come with every plan. Run as many fields and seasons as the work calls for. There's no usage tier and nothing held back for a higher plan; the plans differ by seats, nothing else.
An Individual membership is meant for one lead operator and the support staff on the same client files; agronomists with their own clients take a seat each. Use it as hard as the work needs; we only step in if an account is plainly being shared beyond that or automated.
- Satellite imagery included. Nothing to set up. Sentinel-2 at 10 m, seasons back to 2015, anywhere in the world.
- Elevation loads on its own in the US and Canada, wherever public LiDAR covers the field. Outside that coverage, or anywhere else in the world, upload RTK-quality elevation points and the same terrain tools run on them.
- Every export. A two-page PDF report, a KML that opens in Google Earth with every zone coloured and clickable, shapefile, GeoTIFF and a KMZ picture of the map, rate maps for up to six products with acres beside each rate, soil sampling points, and full project backups.
Start with a field you already have in mind.
