A UAV-Based Multispectral and RGB Dataset for Multi-Stage Paddy Crop Monitoring in Indian Agricultural Fields (IMPaCT-UAV)

Overview

Our dataset presents a large-scale unmanned aerial vehicle (UAV)–based RGB and multispectral imaging collected over the paddy fields in the Vijayawada region, Andhra Pradesh, India. The dataset covers the complete crop growth cycle from nursery to harvest stages and was captured using a 20-megapixel RGB camera and a 5-megapixel multispectral camera equipped with four spectral bands: red, green, red-edge, and near-infrared.

It consists of 42,430 raw images (414 GB) acquired over 5 acres of agricultural land with a ground sampling distance (GSD) of approximately 1 cm/pixel. Each image is accompanied by rich metadata including GPS coordinates, flight altitude, and environmental conditions. In addition to the raw UAV imagery, the dataset repository also includes ‘Processed Images’, which contains orthomosaic, Normalized Difference Vegetation Index (NDVI) and Normalized Difference Red Edge Index (NDRE) maps; ‘Drone_Flight_Checklists’, which provides pre flight, during flight and post flight checklists; ‘Field Records’, which includes Field1 and Field2 records, weather data, and crop calendar activity records; README.txt file provides detailed instructions for dataset usage and organization.

This dataset is a valuable resource for precision agriculture research, including crop health monitoring, disease detection, targeted spraying, and yield estimation.

Data Acquisition Platform

RGB images capture the visible spectrum using red, green, and blue bands, similar to human vision, and are useful for visual interpretation and crop monitoring. Multispectral images capture additional wavelength bands, including red-edge and NIR, which provide critical information about vegetation health, chlorophyll content, and crop stress through vegetation indices.

The dataset was collected using a UAV platform equipped with:

  • RGB Camera: 20 MP (Red, Green, Blue)
  • Multispectral Camera: 5 MP (Red, Green, Red-Edge, Near Infrared)

 Image resolutions:

  • RGB: 5280 × 3956
  • Multispectral: 2592 × 1944
Variation in reflectance for different multispectral bands.

Dataset Organization and Folder Structure

Root Directory
The dataset is organized under a main directory named:

Multistage_Paddy_Crop_Data
This root folder contains raw UAV image data from two agricultural fields along with supporting documents and processed outputs.

1. Folder Naming Convention
Within each field folder, UAV data is organized into date-time folders representing individual flight missions.

Format : FX_XX_YYYY_MM_DD_HHMM_Stage

Where

  • FX → Field identifier
  • F1 = Field001
  • F2 = Field002
  • XX → Survey number
  • YYYY_MM_DD → Capture date
  • HHMM → Capture time
  • Stage → Paddy crop growth stage

Example:
F2_03_2025_08_16_1639_Vegetative_Stage
Third survey of Field002, captured on 16 August 2025 at 16:39 during the Vegetative Stage.

Orthomosaic and Vegetation Index Maps

Captured images were processed using Pix4D Fields to generate: Orhtomosaic , NDVI and NDRE  maps.

  • Orthomosaic maps – A geometrically corrected, high-resolution aerial map created by stitching multiple UAV images into a single seamless image of the entire field.

     

  • NDVI and NDRE are vegetation indices derived from multispectral imagery that help assess crop health and growth conditions. They highlight variations in plant vigor, chlorophyll content, and early stress across agricultural fields. These maps enable large-scale crop health assessment and spatial monitoring of vegetation conditions across the agricultural fields.

Applications

Our dataset, enriched with detailed metadata, enables a wide range of research and precision agriculture applications:

  • Precision agriculture – optimizing farming practices using UAV imagery.
  • Targeted pesticide spraying – identifying stressed or diseased areas for efficient spraying.
  • Early pest and crop stress detection – monitoring subtle changes in crop health.
  • Disease analysis – identifying and tracking crop diseases over time.
  • Growth-stage monitoring – tracking development from nursery to harvest stages.
  • Biomass and yield estimation – estimating crop productivity using image analysis.
  • Vegetation index analysis – using NDVI, NDRE, and other indices to assess plant health.
  • Temporal change analysis – comparing crop conditions across different growth stages.
