Powerful Topography Features

TerraZoner uses LiDAR elevation data to create topography-based management zones optimized for variable rate seeding and precision input management.

Step 1

Import Your Field Boundary

Import an accurate field boundary in industry-standard shapefile format to get started. TerraZoner displays your field boundary on the map so you can confirm the correct location, then you're ready to fetch LiDAR elevation data.

Industry-standard shapefile format
Visual confirmation of field location
Ready to fetch LiDAR terrain data

Step 2

Fetch LiDAR Elevation Data

Automatically download high-resolution LiDAR elevation data for your field. TerraZoner processes this data to calculate Topographic Position Index (TPI) and wetness potential, the foundation for terrain-based zone creation.

Automatic LiDAR download (virtually all US, extensive Canadian coverage)
High-resolution terrain analysis
TPI and wetness potential calculation
Upload elevation shapefile where LiDAR unavailable

Step 3

Generate TPI & Wetness Potential Zones

Create topography-based management zones using Topographic Position Index (TPI) and Wetness Potential analysis. Choose from 2 to 10 zones based on terrain position and moisture accumulation patterns—ideal for variable rate strategies.

2 to 10 management zones
TPI (Topographic Position Index) analysis
Wetness potential mapping
Optimized for variable rate seeding
Instant visual feedback

Advanced

Advanced Terrain Classification

Fine-tune your topography zones with advanced classification methods and adjustment controls. You have complete control over how terrain-based zones are created.

Multiple classification algorithms
Manual zone boundary adjustment
Real-time zone statistics
Terrain position analysis

⭐ VALIDATE YOUR ZONES

Interactive 3D Zone Validation

See your management zones draped over a true 3D terrain model—instantly understand how classifications align with the landscape.

TerraZoner's 3D viewer brings your zones to life. Rotate, zoom, and explore your field from any angle to validate zone boundaries against actual terrain features. Make classification adjustments and watch the results update in real-time—ensuring your zones accurately capture the topographic variations that matter.

Analysis

Topography-Based Zone Delineation

Delineate management zones based on accurate topographic metrics—Wetness Potential and Topographic Position Index (TPI). These terrain-derived zones may be useful for applications such as variable rate seeding, where different plant populations are targeted based on topography-related germination and mortality risk factors.

Topographic Position Index (TPI) classification
Identify landscape positions prone to water accumulation
Export zones for variable rate applications

Export

Flexible Export Options

Export your topography zones in multiple formats to suit your workflow. Download zones as shapefiles for precision ag software, GeoTIFF rasters, or KMZ overlays for Google Earth visualization. You can also download the raw LiDAR elevation data as GeoTIFF and generate professional PDF map layouts for reports and client presentations.

Nearly all major agricultural regions have LiDAR for automatic topography-based zone creation. From the Red River Valley to Iowa's rolling hills, Illinois to Nebraska—green overlay means LiDAR available. No LiDAR? Upload RTK-collected elevation shapefiles.

Use the map above to check LiDAR availability. Green overlay = automatic topography zones. Transparent = upload RTK elevations required.

✓ Get Started

TerraZoner is designed for professional agronomists, agrologists, and crop consultants to create topography-based management zones from LiDAR elevation data. While TerraZoner provides tools for creating prescription files and analyzing terrain characteristics, 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 topography maps, and apply them appropriately within their agronomic practice.

✓ Acceptable Use Cases

✓ One agronomist shares license with their assistant who prepares zone maps
✓ Small 3-person consulting office operating from one location shares one license
✓ Lead consultant shares access with GIS technician and field data collector
✓ Individual farmer uses TerraZoner for their own operation and shares with farm manager

✗ Not Permitted

✗ Two independent agronomists in a partnership sharing one license
✗ Regional consulting team with 4 lead agronomists sharing one license
✗ Multi-location business with separate client portfolios per location using one license
✗ Reselling or sublicensing TerraZoner access to other consultants or businesses

Output Sharing & Client Services

Zone maps, shapefiles, and analysis outputs created with TerraZoner may be freely shared with clients as part of professional consulting services. There are no restrictions on distributing TerraZoner-generated zone maps to your clients for use in their precision agriculture operations.

Prohibited Activities

Unauthorized reproduction, redistribution, or sublicensing of TerraZoner software is strictly prohibited:

✗ Sharing login credentials with individuals who should have their own license
✗ Reverse engineering, decompiling, or modifying the TerraZoner software
✗ Circumventing authentication, usage tracking, or licensing controls
