GeoRDPy is a Python library that simplifies geodetic-coordinate polylines using the Ramer-Douglas-Peucker algorithm. It ensures accuracy by utilizing the precise distance calculations from the GeographicLib by Charles Karney on the WGS 84 reference ellipsoid.

## Features
- Simplify geodetic-coordinate polylines using the Ramer-Douglas-Peucker algorithm.
- Utilize precise distance calculations with GeographicLib on the WGS 84 reference ellipsoid.
- Easy-to-use interface with a single function call.

## Installation
GeoRDPy releases are available as wheel packages for macOS, Windows and Linux on [PyPI](https://pypi.org/project/geordpy/).
Install it using pip:
```bash
$ pip install geordpy
```

## Usage
```python
>>> import numpy as np
>>> import geordpy
>>> points = np.array([(42.0, -75.0), (42.1, -74.9), (42.2, -75.1), (42.3, -74.8)])
>>> threshold = 15_000  # meters
>>> mask = geordpy.filter(points, threshold)
>>> points[mask]
array([[ 42. , -75. ],
       [ 42.2, -75.1],
       [ 42.3, -74.8]])
```

## Contributing
Contributions are welcome! If you find any issues or have suggestions for improvements, please feel free to submit a pull request.

### Development Setup
To set up your development environment, follow these steps:

1. Clone the repository:
   ```bash
   $ git clone https://github.com/avitase/geordpy.git
   ```

2. Change to the project directory:
   ```bash
   $ cd geordpy
   ```

3. Install the development dependencies using `pip`:
   ```bash
   $ pip install -e .[dev]
   ```

### Pre-Commit-Hooks
To maintain code quality and avoid pushing invalid commits, we recommend using pre-commit hooks. These hooks perform automated checks before commits are made. To set up pre-commit hooks, follow these steps:

1. Install the pre-commit package (if not already installed):
   ```bash
   $ pip install pre-commit
   ```

2. Install the hooks:
   ```bash
   $ pre-commit install
   ```

Now, each time you commit changes, the pre-commit hooks will run checks such as formatting, linting, and more. If any issues are found, they will be flagged before the commit is made.

### Running Tests
You can run tests using the following command:
```bash
$ pytest
```

Make sure to run tests before submitting a pull request to ensure that everything is functioning as expected.
