NWPU YRCC GFICE

<!-- Provide a quick summary of the dataset. -->

NWPU_YRCC_GFICE (GFICE) is a satellite remote-sensing semantic segmentation dataset for fine-grained river-ice mapping. It is built from multi-spectral GF-2 satellite imagery over the Yellow River (Ningxia–Inner Mongolia section) and is designed to support hydrological monitoring and ice-flood early warning research.

Dataset Details

Dataset Description

<!-- Provide a longer summary of what this dataset is. -->

The NWPUYRCCGFICE dataset provides pixel-level annotations for river-ice scenes captured from satellite view, addressing the limited spatial coverage of prior river-ice datasets that mainly rely on UAV or ground-based imagery. The dataset covers freeze–thaw cycles and annotates river-ice conditions into eight fine-grained semantic classes.

• —Curated by: Northwestern Polytechnical University (NWPU) research team (authors of the companion paper)
• —License: CC BY-NC-SA 4.0 (cc-by-nc-sa-4.0)

Uses

<!-- Address questions around how the dataset is intended to be used. -->

Direct Use

<!-- This section describes suitable use cases for the dataset. -->

• —Training and evaluating semantic segmentation models for river ice mapping from satellite imagery.
• —Research on fine-grained ice characterization across freeze–thaw cycles.
• —Developing algorithms for hydrological monitoring and ice-flood early warning (research/non-commercial use under the dataset license).
• —Benchmarking segmentation architectures (the companion work evaluates many segmentation models and includes improved YOLO-/SegFormer-based variants).

Out-of-Scope Use

<!-- This section addresses misuse, malicious use, and uses that the dataset will not work well for. -->

• —Commercial use without meeting the constraints of CC BY-NC-SA 4.0.
• —Direct deployment to other rivers/regions/sensors without considering domain shift (different illumination, sediment, width, climate, sensor bands, spatial resolution, etc.).

Dataset Structure

<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->

The dataset is intended for semantic segmentation with mmsegmentation dataset style. A typical sample contains:

• —image: a multi-spectral GF-2 TIFF image
• —label: a per-pixel label map with 8 classes (integer IDs)

Splits (recommended):

• —train set contains 22700 images
• —validation set contains 5675 images

Label schema: The dataset contains eight fine-grained classes for river ice across freeze–thaw cycles.
