+# SFT and RL Traning dataset of GeoZero
+
+
+## Dataset Composition
+
+GeoZero consists of three variants:
+
+| File | Description |
+|------|------------|
+| **GeoZero-Raw.json** | Raw aggregated data across heterogeneous datasets |
+| **GeoZero-Instruct.json** | Unified instruction-tuned dataset for supervised fine-tuning |
+| **GeoZero-Hard.json** | Challenging subset for RL training |
+
+All image files are stored under the `images/` directory.
+
+
+
+## Directory Structure
+
+```
+GeoZero_Train_Datasets/
+├── images/
+│   ├── AID-0000.tar
+│   ├── AID-0001.tar
+│   ├── RSVQA-HR-0000.tar
+│   ├── ...
+│
+├── GeoZero-Raw.json
+├── GeoZero-Instruct.json
+├── GeoZero-Hard.json
+└── Readme.md
+```
+
+If tar shards are used, each tar file preserves relative paths:
+
+```
+RSVQA-HR/8766.png
+```
+
+
+## JSON Format Examples
+
+Each JSON file contains a list of samples in the following structure:
+
+For GeoZero-Raw.json and GeoZero-Instruct.json: 
+
+```json
+{
+  "messages": [
+    {
+      "role": "user",
+      "content": "<image>\n[vqa] Is there a residential building on the right of the university?"
+    },
+    {
+      "role": "assistant",
+      "content": "no"
+    }
+  ],
+  "images": [
+    "RSVQA-HR/8766.png"
+  ]
+}
+```
+
+For GeoZero-Hard.json: 
+
+```json
+{
+  "messages": [
+    {
+      "role": "system",
+      "content": "system prompt"
+    },
+    {
+      "role": "user",
+      "content": "<image>\n[vqa] What is the area covered by residential buildings? Give a response of yes or no."
+    }
+  ],
+  "images": ["RSVQA-HR/118.png"],
+  "solution": "<answer> 1934m2 </answer>\n",
+  "task_type": ["vqa"]
+}
+```
+
+
+## Loading the Dataset
+
+### Load JSON Directly
+
+```python
+import json
+
+with open("GeoZero-Instruct.json", "r", encoding="utf-8") as f:
+    data = json.load(f)
+```
+
+
+
+### Load with Hugging Face Datasets
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset(
+    "hjvsl/GeoZero_Train_Datasets",
+    data_files="GeoZero-Instruct.json"
+)
+```
+
+

+
+```bibtex
