Project Framework

Meet our strategy

CropAuditing is a technological framework designed to enhance the monitoring of large-scale agricultural areas through the integration of satellite imagery (Sentinel-2) and Machine Learning algorithms. Our solution addresses the limitations of traditional manual surveys by providing an automated, scalable, and precise system for crop species identification and growth stage tracking. By converting complex geospatial data into verifiable analytical reports, the platform optimizes the auditing process for financial institutions and insurance companies. We aim to ensure data transparency, facilitate fraud detection, and provide stakeholders with the necessary tools for informed decision-making in the evolving agricultural landscape.

Crop Identification

Crop Identification

Using Machine Learning and statistical analysis to accurately identify crop species and calculate their specific land areas.

Growth Monitoring

Growth Monitoring

Leveraging Sentinel-2 satellite imagery to automatically determine and track the growth stages of plantations.

Automated Auditing

Automated Auditing

Replacing slow manual surveys with a fast and user-friendly digital process for insurance companies and financial institutions.

Fraud Detection

Fraud Detection

Ensuring data transparency to facilitate fraud prevention and simplify compliance with agricultural government aid programs.

Project Value

Problem → Solution → Impact

CropAuditing connects a clear auditing problem with a scalable technical solution and practical value for institutions that need reliable agricultural verification.

01

Problem

Manual agricultural audits are slow, expensive and difficult to scale across large territories. Field inspections require time, people and repeated verification, making the process inefficient for insurers, banks and public-sector entities.

03

Impact

The platform enables faster verification, scalable monitoring and stronger fraud or inconsistency detection, supporting more transparent decisions in insurance validation, agricultural subsidies and financial risk analysis.

Partners

Developed with support and feedback from academic, agricultural and technology stakeholders.

Solution Architecture

How Our Technology Works

CropAuditing transforms satellite imagery and declared agricultural parcel data into automated crop auditing outputs, combining database management, statistical analysis, Machine Learning and Google Earth Engine visualization.

01

Data Sources

Satellite and declared parcel data

CropAuditing Processing Core DuckDB · Python · ML · NDVI

Database Layer

DuckDB stores and queries large volumes of parcel and crop data.

Feature Extraction

Spectral descriptors, temporal curves and vegetation patterns.

Training / Validation

Data split for model development, testing and performance evaluation.

02

Analysis Models

Classification and phenology monitoring

Final Output

Google Earth Engine Web App

User interface for selecting agricultural terrain, visualizing classified parcels and supporting automated crop audit decisions.

Open Web App

We collect and organize agricultural parcel data using EuroCropsV2 and Sentinel-2 satellite imagery. For the current study, the database focuses on Portugal and selected crops such as corn, rye and oats, supporting both model training and validation.

The processing layer uses DuckDB and Python-based analysis to handle large volumes of declared parcel data, extract satellite-derived features, and prepare the datasets used by the Machine Learning models.

The intelligence layer combines Random Forest classification for crop species identification with NDVI time-series analysis for growth stage monitoring. This allows the system to compare declared agricultural information with satellite-derived evidence.

Results are presented through a Google Earth Engine web application, allowing users to select agricultural terrain, visualize classified areas and access practical crop auditing outputs.

Accuracy & F1 Score

Evaluation of crop type and growth-stage classification performance.

Spatial Accuracy

Comparison between predicted crop maps and validated parcel data.

NDVI Curve Error

MAE and RMSE used to compare predicted and observed vegetation curves.

Temporal Error

Evaluation of growth-stage timing from NDVI time-series behaviour.
