## 📚 Introduction
**RSHR-Bench** evaluates ultra-high-resolution remote-sensing visual understanding and reasoning in multimodal large language models across single-image, multi-image, and multi-turn settings. This release embeds original-resolution images directly in Parquet shards for use with Hugging Face Datasets, without a separate `images/` directory or local image-path resolution.
The benchmark covers real-world scenes from public remote-sensing datasets and UAV imagery, including object-level, region-level, temporal, and anomaly-oriented understanding. It accompanies [A Benchmark for Ultra-High-Resolution Remote Sensing MLLMs](https://arxiv.org/abs/2512.17319). [XHRBench](https://huggingface.co/datasets/RL-MIND/XHRBench) belongs to the same benchmark project and uses a different package layout.
## 🎯 Release Statistics
| Item | Original release |
| --- | ---: |
| Examples | 1,932 |
| Split | `test` |
| Parquet shards | 197 |
| Parquet size | 210.14 GiB (225,641,067,559 bytes) |
| Data language | English |
| One-image examples | 1,862 |
| Two-image examples | 50 |
| Three-image examples | 20 |
These figures describe this Parquet package, as documented in the package manifest and original dataset card; they are distinct from image totals for the full benchmark in the paper. The Hugging Face Parquet release with embedded ultra-high-resolution images was published on **2026-05-19**.
## 🌟 Task Coverage
- **Multiple-choice VQA:** Visual decisions within a fixed answer space.
- **Open-ended VQA:** Free-form visual understanding and compositional reasoning.
- **Regional and object-level understanding:** Grounding, counting, classification, object-state judgment, relations, color, and shape.
- **Multi-image and multi-turn reasoning:** Temporal change, future prediction, anomaly detection, and contrastive reasoning across regions or images.
These describe the benchmark's overall task coverage; the fields and category distribution of this package are detailed below. Answers should be grounded in visual evidence. See the [paper](https://arxiv.org/abs/2512.17319) and [code](https://github.com/Yunkaidang/RSHR) for the evaluation protocol.
## 📦 Data Format

data/test-*.parquet # Parquet shards with embedded images
annotations/*.json # Original task annotations
vqa_summary.json # Merged annotation summary

## 🚀 Quick Start
After installing the required dependencies, stream a sample for an initial inspection. The following example disables image decoding; streaming still transfers the necessary shard or image bytes and is not a text-metadata-only download.
```python
from datasets import Image, load_dataset
# Stream a sample and keep image bytes undecoded during inspection.
ds = load_dataset("RL-MIND/RSHR-Bench", split="test", streaming=True)
for column in ("image_1", "image_2", "image_3"):
ds = ds.cast_column(column, Image(decode=False))
first = next(iter(ds))
print(first["id"], first["category"], first["question"])
```
Loading the full split downloads approximately **210.14 GiB** of Parquet data. Allow additional resources for caching and image decoding.
```python
from datasets import load_dataset
ds = load_dataset("RL-MIND/RSHR-Bench", split="test")
print(ds[0]["question"])
print(ds[0]["image_1"])
```

## 💡 Usage Notes
- This release does not include a separate `images/` directory; image bytes are stored inside Parquet files.
- Images retain their original resolution, reaching hundreds of megapixels; decoding can require substantial memory.
- Original path fields provide provenance and do not require downloading separate image files.
- The `test` split is intended for benchmark evaluation. Align task definitions and evaluation settings with the paper when comparing results.
