Autonomous farms
Your mapping is the first step toward farms operating with less and less human intervention.
Mapping Partner network
Available
AG4 Mapper: the mapping kit for certified partners.
With the Mapper and an antenna with corrected signal, AG4 certified partners map fields and become part of the AG4 autonomous farm ecosystem — with early access to what's new.
What sets it apart AG4 ecosystem
Be part of the autonomous farm ecosystem.
An AG4 Mapper partner isn't just buying equipment: they join the network that is building the autonomous farm, together with AG4.
What's new, before everyone else
A profile unlocked in AG4 Atlas as a special customer, testing solutions before launch.
A new service
Offer your customers a field map ready for the machine's optimized route.
How it works Partner network
Mapping is done by certified partners.
AG4 is building a network of partners who take AG4 Mapper to the field. The grower receives the mapped field, ready for route planning.
Gets the kit and is certified
The partner receives AG4 Mapper and goes through AG4 certification.
Maps the fields
With the antenna with corrected signal, they cover the area and record the boundary, obstacles and areas to avoid.
Map ready for Atlas
The survey goes to AG4 Atlas, which calculates the machine's optimized route.

Certified partners across Brazil.
Mapping is done by AG4 Mapper certified partners. To get service, talk to AG4: we learn about your area and refer you to the partner in your region.

The kit AG4 Mapper
Two options. You choose the antenna.
AG4 Mapper collects data in the field with your phone. Get it with the Nordian antenna and corrected signal already included, or use the compatible antenna you already have.
Compatible antennas
- Nordianincluded in the option with antenna
- Trimble NAV-900
- NovAtel
- John Deere StarFire 6000
- Generates field boundaries
- Marks obstacles and points of interest
- More accuracy and less rework
- Easy to use in the field
Product in the field
Easy to carry. Easy to use.
AG4 module and antenna with corrected signal, mounted on a light vehicle — such as a motorcycle — and monitored from your phone. The survey is done by driving around the area.
- ModuleAG4 Mapper
Records the points and the path of the survey.
- AntennaCorrected signal
Every point on the map comes from a corrected position, with the accuracy the machine needs to work.
- PhoneMonitoring
The survey is monitored from your phone along the way.
Mapping workflow Step by step
From field to file, in six steps.
The partner covers the area with the Mapper and the antenna with corrected signal. Each element of the field is recorded with its type, and at the end you get a file package ready for AG4 Atlas.
- 01Identify the field
Choose the farm and the field. Each survey gets a number and is recorded with date and time.
- 02Connect the antenna
The Mapper receives the position from the antenna with corrected signal and tracks signal quality throughout the route.
- 03Choose what to record
Field boundary, no-go area, obstacle, road, gate, refueling point or unloading point.
- 04Drive the outline
The Mapper records points at short distance intervals — in the sample survey, one point every 30 cm. For a pole, a single point with the safety radius is enough.
- 05Finish
When you finish, the Mapper closes the outlines and generates the field files, along with the survey quality report.
- 06Send to Atlas
The operational map goes to AG4 Atlas, which calculates the machine's optimized route.
If speed exceeds the recommended limit for keeping the spacing between points, the Mapper warns you — and the warning is recorded in the report.
Real example The generated map
The field, as it really is.
Real survey of a field: boundary, a waterlogged area the machine must avoid and four poles recorded as obstacles, each with a safety radius.
Field boundary
Area to avoid
Obstacles
What can be recorded
- Field boundary
- No-go areas, with the reason
- Cleared areas
- Obstacles, with safety radius
- Roads
- Gates
- Refueling points
- Unloading points
The generated file GeoJSON
One file package per survey.
At the end of the route, the Mapper creates a folder for the field with the elements separated by type, the complete operational map and the quality report. Maps are exported as GeoJSON, an open format that also opens in QGIS and other GIS software.

Who, where and when
Farm, field, survey number, equipment used, end date and time, distance covered and how many elements of each type were recorded.
Was the survey good?
- How much of the route was done with fixed corrected signal
- Corrected signal losses: how many and for how long
- Actual spacing between points and completeness of the collection
- Satellite geometric quality (HDOP)
- Speed warnings
- Final survey rating
Nothing gets lost
A new survey of the same field creates a new dated folder. Previous versions are kept.
{
"type": "Feature",
"properties": {
"feature_type": "OBSTACLE",
"obstacle_type": "POLE",
"safety_radius_m": 2,
"position_method": "SNAPSHOT",
"fix_type": "RTK_FIXED"
},
"geometry": { "type": "Point", "coordinates": [lon, lat] }
}Each element carries its type and the data the route needs: here, a pole recorded as a single point, with a 2 m safety radius and fixed corrected signal.

The boundary is recorded where the field really ends — at the border with the road.
Mapper → Atlas
The map becomes a route.
The survey goes to AG4 Atlas, which uses the boundary and the recorded elements to calculate the machine's optimized route.

Frequently asked questions.
What do I gain by becoming a partner?
You become part of the AG4 autonomous farm ecosystem, with early access to what's new and a special customer profile in AG4 Atlas, testing solutions before everyone else.
Who does the mapping?
AG4 certified partners, who use AG4 Mapper. If you need your area mapped, AG4 will refer you to a partner.
How do I become a partner?
Fill out the “Become an AG4 partner” form on this page or message us on WhatsApp. AG4 will present the kit, the terms and the certification process.
What comes in the Mapper kit?
Two options: with antenna (AG4 Mapper, Nordian antenna and corrected signal included for 1 year) or without antenna (AG4 Mapper to use with your compatible antenna). Both include an AG4 Atlas profile as a special customer and a place in the autonomous farm ecosystem.
Which antennas are compatible?
Nordian, Trimble NAV-900, NovAtel and John Deere StarFire 6000.
What can be recorded?
Field boundary, no-go areas (with the reason, such as water), cleared areas, obstacles (with type and safety radius), roads, gates, refueling points and unloading points.
What format is the map in?
GeoJSON. Each survey generates a folder with the boundary, no-go areas and obstacles in separate files, the complete operational map, the survey identification (manifest.json) and the quality report (quality.json).
Can I open the files outside AG4 Atlas?
Yes. GeoJSON is an open format and opens in QGIS and other GIS software.
How do I know if the survey was good?
From the quality report: it shows how much of the route was done with fixed corrected signal, signal losses, the actual spacing between points, speed warnings and the final survey rating.
Where does the map go?
To AG4 Atlas, where it becomes the basis for the machine's optimized route.
