Crop Classification Data for Donggang City Using Sentinel-1 and Sentinel-2 Imagery

19.6 MB of data and code supports a study on crop classification in Donggang City, Liaoning Province, China. It includes sample points for land cover types, multi-source remote sensing features from Sentinel-1 SAR and Sentinel-2 optical imagery, and classification model implementations. The dataset was created by Cong Gao and last updated on 2026-04-19.

Use Cases

• Training supervised crop classification models based on labeled sample points for maize, rice, and other land cover types.
• Analyzing the effectiveness of multi-source remote sensing features, including spectral bands, vegetation indices, and temporal statistics, for crop mapping.
• Comparing the performance of Random Forest and other classification models for generating crop maps.
• Conducting feature selection to reduce redundancy and improve classification performance using the provided code.
• Reproducing and extending research on crop classification in a specific geographic area (Donggang City).

Strengths

• Includes both data (sample points, features, mapping results) and executable code for feature construction, preprocessing, and model implementation.
• Data is provided in standard formats (TIF, TXT, PY, CSV) and uses the WGS 84 coordinate system (EPSG:4326).
• Explicitly designed to support reproducibility in crop classification and multi-source data fusion research.

Limitations

• Row count and specific column details are unknown, which may limit suitability assessment for specific modeling tasks.
• Geographic scope is limited to Donggang City, Liaoning Province, China, which may affect generalizability.
• Column-level documentation is absent; field semantics must be inferred after download.
