# WildfireSimMaps

## Description

This is a dataset containing real-world map data for wildfire simulations. 
The data is in the form of 2D maps with the following features:

- `name`: The name of the map data.
- `shape`: The shape of the area, in pixels.
- `canopy`: The canopy cover in the area, in percentage.
- `density`: The density of the area, in percentage.
- `slope`: The slope of the area, in degrees.

## Quick Start

Install the package using pip:

```bash
pip install datasets
```

Then you can use the dataset as follows with **NumPy**:

```python
import numpy as np
from datasets import load_dataset

# Load the dataset
ds = load_dataset("xiazeyu/WildfireSimMaps", split="train")
ds = ds.with_format("numpy")

def preprocess_function(examples):
    # Reshape arrays based on the 'shape' field
    examples['density'] = [d.reshape(sh) for d, sh in zip(examples['density'], examples['shape'])]
    examples['slope'] = [s.reshape(sh) for s, sh in zip(examples['slope'], examples['shape'])]
    examples['canopy'] = [c.reshape(sh) for c, sh in zip(examples['canopy'], examples['shape'])]
    
    return examples

ds = ds.map(preprocess_function, batched=True, batch_size=None)  # Adjust batch_size as needed

print(ds[0])
```

To use the dataset with **PyTorch**, you can use the following code:

```python
import torch
from datasets import load_dataset

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

# Load the dataset
ds = load_dataset("xiazeyu/WildfireSimMaps", split="train")
ds = ds.with_format("torch", device=device)

def preprocess_function(examples):
    # Reshape arrays based on the 'shape' field
    examples['density'] = [d.reshape(sh.tolist()) for d, sh in zip(examples['density'], examples['shape'])]
    examples['slope'] = [s.reshape(sh.tolist()) for s, sh in zip(examples['slope'], examples['shape'])]
    examples['canopy'] = [c.reshape(sh.tolist()) for c, sh in zip(examples['canopy'], examples['shape'])]
    
    return examples

ds = ds.map(preprocess_function, batched=True, batch_size=None)  # Adjust batch_size as needed

print(ds[0])
```

## Next Steps

In order to make practical use of this dataset, you may perform the following tasks:

- scale or normalize the data to fit your model's requirements
- reshape the data to fit your model's input shape
- stack the data into a single tensor if needed
- perform data augmentation if needed
- split the data into training, validation, and test sets

In general, you can use the dataset as you would use any other dataset in your pipeline.

And the most important thing is to have fun and learn from the data!
