Abstract 

This study introduces a novel soil texture dataset designed to overcome geographic constraints and improve the generalization of classification models. Using the USDA soil classification triangle as a framework, the dataset is systematically generated by combining pure sand, silt, and clay in varying proportions to create diverse soil texture classes. The soil mixtures are captured using a multispectral sensor with seven bands, ensuring a rich representation of spectral information. This self-generated dataset enables the development and evaluation of advanced classification techniques, offering a standardized and comprehensive resource for soil texture studies. By addressing the limitations of existing datasets, this work provides a robust foundation for advancing soil texture classification research across diverse fields.

Instructions: 
  • The dataset consists of soil samples created by manually mixing pure sand, silt, and clay in specific proportions based on the USDA soil classification triangle. The mixture encompasses a wide range of soil texture categories, providing a comprehensive dataset for classification tasks.
  • Soil samples were captured using the Parrot Sequoia multispectral sensor, which records data in seven distinct bands: RGB (Red, Green, Blue), Green, Red, Red Edge (REG), and Near Infrared (NIR). These bands offer a rich, multidimensional view of the soil's spectral characteristics.
  • The dataset includes the proportion table, which outlines the exact composition of each soil mixture and the corresponding seven-band images for each sample, allowing for detailed analysis and classification of soil textures.
