GIS4Ag PowerZoner™
You've walked those fields. You know what the data should show.
Stop outsourcing your expertise - build the zones yourself.
PowerZoner
See what you've always suspected - hilltops and depressions finally separated. Satellite zones refined by terrain & wetness.
TerraZoner
Maps that match what you see walking the field. Pure terrain-driven zones for VR seeding, spraying, and fertility.
Your Agronomy, Amplified
Great zones come from great agronomists - not expensive subscriptions or service providers. These tools let you apply what you know, test different approaches, and refine until the map matches reality. No per-acre fees. No waiting. No outsourcing. You are in control.
See What You've Always Known
You've scouted these fields. You know that hilltop and that low spot need different treatment - even though they both show up as "low productivity" in standard NDVI. PowerZoner finally separates them. Zones that match your instincts.
Zones That Finally Make Sense
You've always known that hilltop and that wet corner need completely different management - even though both show up "red" on standard maps. PowerZoner uses LiDAR or SAR-based moisture data to split low productivity into wet-limited and dry-limited areas. Now your prescriptions can reflect what you've seen for years.
How It Works
Load Field Boundary
Import your field boundaries in standard shapefile format. Works with boundaries from any GIS software or precision ag platform.
Fetch Multi-Year Satellite Data
Fetch peak biomass NDVI from Sentinel-2 back to 2015. Preview each year, select which seasons to include, remove drought or hail years.
Generate Management Zones
Create 2-10 productivity zones using a Crop Productivity Index (CPI) derived from multi-year NDVI analysis.
Advanced Classification
Fine-tune zone boundaries with multiple classification algorithms. Adjust parameters to match local conditions.
Topo-Refined Zones with Wetness Index
You've seen it a hundred times: that "low productivity" zone lumps drought-prone hilltops with waterlogged depressions. Everyone knows these aren't the same agronomically. NDVI can't tell the difference - but terrain can. PowerZoner uses LiDAR-derived wetness indices to split these apart, so your low zones actually mean something when you're writing rates.
SAR Wetness Alternative
Where LiDAR isn't available, split low zones into wet and dry based on Synthetic Aperture Radar (SAR) soil moisture captured during spring thaw and post-harvest. Available globally.
3D Terrain Viewer
Visualize zones draped over true 3D terrain models. Validate zone boundaries against actual landscape features.
Maps That Match How The Field Looks
Take advantage of free high-resolution LiDAR data covering most of the US and expanding across Canada. Where LiDAR isn't available, import your own RTK or drone elevation data. Ridges, slopes, and depressions mapped exactly as you'd draw them yourself.
Trust Your Terrain Knowledge
You can spot a knoll or depression from the cab. Now get zones that match. TerraZoner maps where water will be scarce or excessive based purely on terrain - no yield data history needed, no waiting on satellite passes. Just landscape truth that supports your VR seeding decisions.
How It Works
Import Field Boundary
Load your field boundaries in shapefile format from any GIS software or precision agriculture platform.
Automatic LiDAR Download
TerraZoner automatically fetches high-resolution LiDAR elevation data. Extensive US and expanding Canadian coverage.
TPI & Wetness Zones
Generate 2-10 zones based on terrain position and moisture potential. Identify ridges, slopes, flats, and depressions.
Advanced Terrain Classification
Fine-tune topography-based zones with advanced classification parameters. Adjust TPI window sizes and wetness thresholds.
Interactive 3D Validation
See your zones draped over a true 3D terrain model. Rotate, zoom, and validate alignment with landscape features.
Bring Your Own Elevation
Where LiDAR isn't available, upload your own elevation data: RTK point shapefiles, drone LiDAR GeoTIFFs, or other sources.
Your Instincts, Mapped
You know where to sample - the tools just remember. Place points exactly where your experience tells you, then navigate to those same spots year after year. No algorithm picks better than an agronomist who knows the field.
Zone-Based Soil Sampling Tool
Place sampling points exactly where your agronomic instincts tell you - within each zone, guided by your field knowledge. Save locations and navigate to the same GPS coordinates year after year for consistent, repeatable sampling. Works with zones from either PowerZoner or TerraZoner.
Shapefile Export
Export zones as industry-standard shapefiles compatible with all precision ag platforms, farm management software, and equipment.
VR Prescription Generator
Convert zones into variable rate prescriptions. Set seeding rates, fertilizer rates, or any input by zone for direct equipment loading.
Multiple Export Formats
Beyond shapefiles, export to GeoTIFF, KMZ for Google Earth, and PDF map layouts for reports and client presentations.
Unlimited Zone Creation
No per-field or per-acre fees. Create zones for unlimited fields across your entire client base with a single annual subscription.

Topo-Refined Zones Where LiDAR Exists. SAR* Everywhere.
PowerZoner works everywhere. LiDAR enables automatic topo-refined zones where available. Where LiDAR isn't available, use Synthetic Aperture Radar (SAR) moisture data—available globally—or upload your own RTK elevation data. TerraZoner works where LiDAR is shown on these maps, or anywhere with uploaded RTK data.
CA In Canada? Check Your Coverage
Virtually complete LiDAR coverage across Ontario. Complete coverage in southern Manitoba, with expanding coverage in Saskatchewan and Alberta. Where LiDAR exists, PowerZoner automatically creates topo-refined zones. No LiDAR? Use SAR moisture data (available globally) or upload RTK elevation data.
Use the map above to check LiDAR availability. Areas with visible hillshade have auto topo-refined zones available.
✓ Get StartedUS In the USA? Check Your Coverage
Nearly all major agricultural regions have LiDAR for auto topo-refined zones. From the Red River Valley to Iowa's rolling hills, Illinois to Nebraska—green overlay means LiDAR available. No LiDAR? Use SAR moisture data (available globally) or upload RTK elevation data.
Use the map above to check LiDAR availability. Green overlay = auto topo-refined zones. Transparent = use SAR moisture or upload RTK elevations.
✓ Get Started*SAR is experimental and may not work as intended in all situations, particularly where there may be standing water at certain times of the season.

Professional Tool Notice
PowerZoner is designed for professional agronomists, agrologists, and crop consultants to create satellite-based management zones from multi-year NDVI data. While PowerZoner provides tools for creating prescription files and analyzing crop variability, it does not provide agronomic advice, interpretation, or recommendations regarding seeding rates, input application strategies, or any other agronomic decision-making. Users are expected to possess the professional expertise necessary to determine appropriate input rates, interpret zone maps, and apply them appropriately within their agronomic practice.
