Description
The Xunwu River Basin in southern China is the focus of this multi-temporal land use and land cover dataset. It contains pixel-based classification labels for citrus orchards under protective screens, uncovered citrus, forest, and other land, derived from Sentinel-2 and Sentinel-1 satellite imagery from 2018 to 2025. The dataset was released in 2026 by a single researcher using the Google Earth Engine platform and visual interpretation, with reported annual classification accuracy exceeding 90%.
Use Cases
Mapping the expansion dynamics of citrus orchards covered with protective screens based on the multi-temporal classification labels.
Conducting change detection and time-series analysis based on the eight-year period of land cover data.
Training and validating remote sensing classification models for agricultural land use based on the visually interpreted sample points.
Studying the impact of protective screens on orchard land cover classification based on the distinct category labels.
Strengths
Covers an eight-year period from 2018 to 2025, enabling longitudinal analysis.
Reported overall classification accuracy exceeds 90% for each year, with user's and producer's accuracies for citrus orchard classes consistently above 88%.
Sample points were verified against high-resolution Google Earth imagery and underwent cross-validation across years for consistency.
Data is provided in GeoTIFF format, a standard for geospatial analysis.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
The dataset size of 152.8 MB is provided, but the spatial resolution and exact pixel count are not specified in the available metadata.
