## Geospatial Primitives, Algorithms, and Utilities

### Chat or ask questions on [Discord](https://discord.gg/Fp2aape)

The `geo` crate provides geospatial primitive types such as `Point`, `LineString`, and `Polygon`, and provides algorithms and operations such as:

- Area and centroid calculation

- Simplification and convex hull operations

- Euclidean and Haversine distance measurement

- Intersection checks

- Affine transforms such as rotation and translation

- All DE-9IM spatial predicates such as contains, crosses, and touches.

Please refer to [the documentation](https://docs.rs/geo) for a complete list.

The primitive types also provide the basis for other functionality in the `Geo` ecosystem, including:

- [Coordinate transformation and projection](https://github.com/georust/proj)

- Serialization to and from [GeoJSON](https://github.com/georust/geojson) and [WKT](https://github.com/georust/wkt)

- [Geocoding](https://github.com/georust/geocoding)

- [Working with GPS data](https://github.com/georust/gpx)

## Example

```rust

// primitives

use geo::{line_string, polygon};

// algorithms

use geo::ConvexHull;

// An L shape

let poly = polygon![

    (x: 0.0, y: 0.0),

    (x: 4.0, y: 0.0),

    (x: 4.0, y: 1.0),

    (x: 1.0, y: 1.0),

    (x: 1.0, y: 4.0),

    (x: 0.0, y: 4.0),

    (x: 0.0, y: 0.0),

];

// Calculate the polygon's convex hull

let hull = poly.convex_hull();

assert_eq!(

    hull.exterior(),

    &line_string![

        (x: 4.0, y: 0.0),

        (x: 4.0, y: 1.0),

        (x: 1.0, y: 4.0),

        (x: 0.0, y: 4.0),

        (x: 0.0, y: 0.0),

        (x: 4.0, y: 0.0),

    ]

);

```
