What is Agriculture Drone Mapping?
Agriculture drone mapping is the process of using unmanned aerial vehicles (UAVs), commonly known as drones, to collect aerial data on crops, soil, livestock and more. The drone uses cameras and other sensors to capture images, video, thermal data, and multispectral information as it flies over fields.
This data is then processed by specialized software to create detailed 2D and 3D maps, models, and analytics. Common maps derived from drone mapping include:
- Orthomosaic maps – aerial photos stitched together for an overview of an entire field.
- Digital surface models – 3D representations of the terrain and topography.
- Point clouds – detailed 3D models made of millions of coordinate points.
- NDVI maps – images showing crop health based on near-infrared light absorption.
In addition to maps, drone mapping generates accurate measurements, scouting reports, yield predictions and vegetation indices that provide key insights into crop performance.
Major Applications of Drones in Agriculture
Agricultural drones have a wide range of uses across the planting, growing and harvesting process. Here are some of the most common drone mapping applications:
Soil Analysis and Field Planning
- Create 3D maps of farmland for drainage, nutrient deficiency and irrigation planning.
- Survey and map topography to determine optimal locations for planting.
- Assess moisture levels and requirements throughout fields.
- Use NDVI analysis to determine crop readiness for planting.
- Create variable-rate planting prescription maps based on soil analysis.
- Monitor and guide machinery for efficient planting patterns.
Crop Monitoring and Management
- Visually inspect crops to identify pest damage, weed infestations, nutrient deficiencies, etc.
- Calculate vegetation indices like NDVI to assess crop health and growth.
- Create variable-rate prescription maps for applying fertilizer, pesticides, irrigation etc.
- Guide machinery for precise spraying, fertilizing and harvesting applications.
Yield Estimation and Reporting
- Use orthomosaic maps and 3D models to estimate acreage and crop inventory.
- Generate detailed crop progress reports for insurance claims and government audits.
- Continuously monitor fields to predict final crop yields.

How to Choose Drone Mapping Software
Once you have a drone, you need software to process the images and data it captures. There are a few options to consider:
Off-the-Shelf Drone Mapping Software
Many consumer and commercial drones include their own basic software. DJI and other drone manufacturers bundle user-friendly apps to generate maps, 3D models, and basic analytics. While convenient, built-in software often lacks advanced features needed for agriculture.
Specialized Agriculture Drone Software
For professional agricultural use, specialized drone mapping software typically delivers the best results. Leading options like Pix4Dfields, Drone Deploy, and DJI Terra offer advanced analytics, vegetation index calculations, easy prescription map generation, and integration with farm management information systems.
Custom Drone Mapping Solutions
For advanced users with specific needs, custom software development is an option. Custom drone mapping apps can incorporate specialized data inputs, analytics, machine learning, and automation tailored to your farm. They also allow seamless integration with existing equipment and processes.
When selecting software, it’s important to consider your budget, technical capabilities, and the types of data analytics you want to leverage. User-friendly mobile apps offer convenience, while advanced platforms provide more detailed insights.
Getting Started with Drones for Agriculture
Interested in leveraging drones on your own farm? Here are some tips to get started:
Choose a drone optimized for agricultural applications – Look for UAVs that offer swappable cameras, sensors, and flight times over 20 minutes. Rugged, waterproof designs perform best in farm environments.
Select sensors tailored to your needs – RGB cameras provide visual data, while multispectral and hyperspectral cameras gather specialized crop analytics. Also consider LiDAR for detailed 3D terrain modeling.
Start small to learn the ropes – Before mapping your entire farmland, practice with test flights over smaller representative areas. Master flying, image capture techniques, and data analysis.
Invest in durable storage and computing power – Drone mapping generates huge image datasets. Have robust data management and processing capabilities on hand.
Consider hiring professionals your first time – Agricultural drone mapping has a learning curve. Contracting experts your first time can jumpstart the process.
Integrate drone data into your processes – To get the most value, incorporate drone maps, models, analytics and reports into your existing farm management systems.
Case Studies and Examples
Avocado growers use drone technology to measure water loss in orchards
Thermal imaging and drones are used to calculate water loss through transpiration. The technology helps farmers use water more efficiently and produce better fruit. Knowing the amount of water trees transpire can improve overall tree health and fruit quality. Drones equipped with thermal imaging can identify areas of the orchard that require more irrigation.

Marcos Esteve Pamias, a farmer in Spain, implemented precision farming to reduce costs and environmental impact. Using PIX4Dfields, Marcos was able to identify areas affected by weeds and create a prescription map for targeted herbicide application, saving 56% on costs. The project reduced herbicide applied per hectare, halving the product used and cost, and promoting sustainability and environmental friendliness. PIX4Dfields enabled Marcos to quickly collect data, process imagery, and analyze results. Read Case Study.
