Ten-plus seasons of the same field, from space.
Every zone method in TerraZoner, from Composite Zones to one-click Performance Zones, starts with the same source: Sentinel-2, the satellite program the European Space Agency runs through Copernicus. It's open data — global coverage, a decade-plus of growing seasons already on file for a field before you ever draw its boundary.
Pixel size — small enough to trace a real zone boundary, not guess at one.
Every growing season since, already on file the moment you draw the boundary.
Sentinel-2 flies over cropland everywhere. Coverage is never the reason a field gets left out.
Public data from the European Space Agency's Copernicus programme — not a licensed feed you pay extra for.
What that history buys a zone map: one wet spring, or a stand that never came in right, proves nothing on its own. Ten-plus seasons of the same field give every zone method a real pattern to draw from, and one odd season can’t drag the lines on its own.
Each season, TerraZoner reads how green and thick the crop got at its peak — the crop-vigor reading known as EVI2, with the older NDVI (classic) reading still one click away. Performance Zones grades every field against that same history on a fixed scale, so when the imagery says a field doesn’t have enough difference across it to be worth zoning, the result says so in plain words.
Elevation that shows up on its own, or comes from your own GPS.
Automatic where public LiDAR covers the field. Uploaded everywhere else.
Load a boundary in the US or Canada and, wherever public LiDAR covers it, elevation is already there — USGS 3DEP for the US, HRDEM for Canada, pulled in automatically. Nothing to upload, nothing to set up. Coverage isn't wall to wall yet, so check the field's area on the live map below. Where there's no LiDAR, or anywhere else in the world, upload your own RTK-quality elevation points as a zipped point shapefile and TerraZoner builds the same terrain model from them.
What elevation adds
-
Terrain refinement.
Split the zone that's actually giving you trouble into wetter and drier ground, without a terrain pass on the rest of the field.
-
Landscape Response.
A whole-field read on position — high ground, low ground, slope — lined up against how the ground has actually performed.
-
3D view.
Tilt the field into 3D and see the terrain underneath the zone lines before deciding whether a refine pass is worth running.
Check your area
These maps show where public 1 m LiDAR elevation exists in the United States and Canada — the same public services TerraZoner checks the moment a boundary loads. Each map draws the government coverage layer live, so what you see is what the app will find today. If that service is offline, the map falls back to the published 1 m LiDAR project outlines from the same public archives.

Outside the highlighted areas, elevation comes from your own survey instead: upload RTK-quality elevation points and TerraZoner builds the same terrain model from them.
