Terms & Privacy

The full terms of service and privacy policy are below.

One fact worth stating plainly: satellite imagery is requested by TerraZoner on the operator's behalf. Field boundaries and project files stay in the operator's browser and in the exports the operator creates.

Damage estimates: acres reported by the In-Season damage assessment are estimates from satellite imagery, provided as documentation support only. TerraZoner makes no guarantee that any report will be accepted by an insurer, adjuster or other party as the actual damaged acres, and accepts no liability for any claim, settlement or decision made in reliance on it.

Terms of Service

These Terms of Service (“Terms”) are provided by 17449275 Canada Inc., a corporation operating in Manitoba, Canada (“the Company”). By using TerraZoner, you agree to these Terms. If you disagree, discontinue use immediately.

What TerraZoner Is

TerraZoner is a web-based tool for satellite-derived productivity zone mapping, used by agronomists and consultants to analyze fields. The tool also accesses public elevation and weather data to support analysis.

What We Don’t Warrant

TerraZoner outputs are estimates and planning aids only. They are not substitutes for professional engineering, agronomy, surveying, or regulatory approvals. The Company makes no warranty regarding yield, profit, soil outcomes, environmental compliance, or performance of any prescription or action derived from the tool.

Your Account & Use

  • Your login is for you and the people working with you on the same client files, as set out in Licensing. Lending it or sharing it with anyone else is prohibited.
  • You may not overload systems, bypass technical controls, violate third-party licenses, reverse-engineer, use automated scripts or bots, or access accounts without authorization.
  • Field boundaries and project files are processed in your browser and remain your property. They are not uploaded to our servers unless you explicitly export them.
  • Satellite data is retrieved from public APIs using minimal operational metadata.

Data Sources

TerraZoner accesses public elevation data from the U.S. Geological Survey (USGS 3DEP), Natural Resources Canada (NRCan HRDEM), the Province of British Columbia (LidarBC) and the Copernicus DEM (GLO-30, © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014-2018, provided under COPERNICUS by the European Union and ESA), and Sentinel-2 satellite imagery from the Copernicus programme, served through the Company’s imagery providers. You are responsible for downstream compliance with any licensing or attribution requirements of these data sources.

Service Availability

TerraZoner depends on third-party infrastructure and public data sources, which may be unavailable or removed by providers. The Company provides no service-level agreement and offers no refunds or credits for outages or data unavailability, apart from the 30-day refund under Subscriptions & Refunds.

File Processing

TerraZoner processes field boundaries, uploaded survey and elevation points and project files in the browser; they are not stored by the Company, and a project backup is a file the operator downloads and keeps. A request for satellite imagery passes the area of the field to the imagery provider on the operator’s behalf. Where a Company service does receive a file, it is retained only during processing and for two hours thereafter, then deleted; the Company does not keep backups of user-uploaded files.

Subscriptions & Refunds

You can ask for a full refund within 30 days of your first membership payment, for any reason, by contacting us. After that, and on renewals, membership fees are non-refundable except where required by law. Subscriptions auto-renew unless cancelled before the renewal date.

Liability

The Company is not liable for indirect, consequential, or punitive damages. Direct liability is capped at the amount you paid in the preceding twelve months. Any claim must be brought within twelve months after it arises, or it is permanently barred.

Changes to the Service

Algorithm updates may produce different zone outputs for the same field boundary. Features may change without notice.

Governing Law & Dispute Resolution

These Terms are governed by the laws of the Province of Manitoba, Canada, and Manitoba courts have exclusive jurisdiction. Before initiating formal legal proceedings, contact the Company via the contact form at gis4ag.com/contact and allow thirty days to attempt informal resolution.

Effective Date: November 6, 2026
