About TerraZoner
I built the zone tool I spent fifteen-plus years looking for.
I'm Simon Knutson. In all those years I never found a zone map that showed why the lines were where they were. TerraZoner shows you the seasons behind the lines.
- Global satellite coverage
- Browser based, nothing to install
The agronomy stays with you. The tool takes on the sourcing and processing, which I'd put at maybe one or two days per field.
- Satellite imagery included
- 7-day trial, with a Google Meet demo first if you want one
A zone map where every line can be explained
Every zone map I was handed was a picture with no reasoning behind it. No reason a corner got its own zone, and no way to tell whether the field was worth splitting at all. I wanted a map built from years of the field's own record, with lines I could explain to anyone, even on a field that barely needed splitting. TerraZoner is that tool.
Simon Knutson brought the "explain every line" standard from years of standing next to the people who use what gets built.
The years
The field's own record sets the lines, from the seasons you pick.
The ground
Terrain refinement and Landscape Response, using LiDAR where it covers the field, satellite elevation everywhere else, or RTK-quality points.
This season
In-Season: the latest clear scenes for a field, and damage estimates with a report.
Three tools from the same years in the field
TerraZoner is one of three tools Simon Knutson has built or co-built. The other two are for drainage.
TerraZoner
Zones, rate maps and in-season scenes for your fields. An independent GIS4AG product, founded and owned by Simon Knutson.
See what it doesGeo-Surface Pro
Drainage design that runs in the browser, also built by Simon under GIS4AG.
Visit geo-surface.comDitch Assist
On-machine grade control for putting drainage designs in the ground. A Northern Plains Drainage Systems product, with Simon as co-owner and creator/developer.
Visit ditchassist.comYou don't need the other two to get everything TerraZoner offers.
Tools you can put your name on
A zone map carries a name and a reputation. TerraZoner carries mine.
The data decides
Performance Zones lets years of record pick the zones. One odd season is limited in how far it can pull the result, and it's flagged so you can see it.
Support from the people who built it
Questions go to the people who build, test and support TerraZoner.
Imagery and elevation built in
Satellite imagery is included with membership, and the elevation comes with it. You can upload your own RTK-quality points too.
Draw a boundary and read the field
Request a free trial, draw a boundary, and see the years and the ground, all in your browser.
The trial runs 7 days, with a Google Meet demo first if you want one. If you then join, your first membership payment has a 30-day refund.
