## 🌄 Overview

`elevatr` is a Python library designed for downloading and processing elevation data. It is particularly useful for geospatial analyses and visualizations. The library supports high-resolution raster data and offers easy-to-use tools for displaying and exporting elevation information. 🗺️📊

<!---------------------------------------------->

## 📦 Installation

To install `elevatr`, run the following command:

```bash
pip install elevatr
```

<!---------------------------------------------->

## 🛠️ How To Use

### 📥 Download Elevation Data

Here is a simple example of how to use `elevatr` to download elevation data:

```python
import elevatr as elv

# Define the bounding box of the area of interest (min_lon, min_lat, max_lon, max_lat)
bbx = (-5.14, 41.33, 9.56, 51.09)

# Set the level of precision (between 0 and 14)
zoom = 6

# Access the elevation data
raster = elv.get_elev_raster(locations=bbx, zoom=zoom)
```

> **📝 Note:**
> Please choose the zoom level incrementally, a high level of zoom on a large area can take a lot of time and memory.

### 🖼️ Display the elevation data:

```python
raster.show(cmap='terrain', clip_zero=True)
```

#### 🌍 Example output:

<div style="text-align: center;">
    <img src="https://raw.githubusercontent.com/titouanlegourrierec/elevatr/main/assets/raster_example.png" alt="alt text" width="50%">
</div>

### 🏔️ Visualize in 3D

```python
raster.show_3d(
    solid=True,
    light_intensity=0.5,
    transparent_background=True,
    zscale=40,
    phi=30,
    theta=180,
    file_path="elevation.png",
)
```

Render a stunning 3D view of your elevation data! 🌐✨

#### 🌍 Example output:

<div style="text-align: center;">
    <img src="https://raw.githubusercontent.com/titouanlegourrierec/elevatr/main/assets/3d_raster_example.png" alt="alt text" width="50%">
</div>

### 💾 Save to TIFF File

```python
raster.to_tif("elevation.tif")
```

Save your elevation data to a TIFF file for further use! 🗂️✨
