This dataset contains multispectral UAV image samples, derived training patches, metadata, and trained CNN models for agricultural sub-class classification. The samples were collected using RGB and CIR UAV sensors with ground sampling distances (GSD) of 0.027 m, 0.053 m, and 0.064 m, and were resampled to spatial resolutions of 0.060 m and 0.080 m. Data was acquired over agricultural sites in Germany and structured by crop type - Winter Wheat (WW), Spring Barley (SG), Rapeseed (WR), and Corn (KM) - with labels assigned using a thematic sub-class labeling system based on the BBCH scale (vital/dry crop, vital/dry lodged crop, ripening/flowering crop, bare soil and weed infestation). The dataset includes raw (tif) and augmented image patches, patch matrices, and TensorFlow CNN models trained separately for each crop type. Each ZIP file includes a dedicated README.txt. A complete project-wide README.md is provided with this record, detailing the sampling strategy, structure, licensing, and references. This dataset supports the study under review titled: *Toward Generalizable CNN-Based Classification of Agricultural Sub-Classes*.
