Geospatial Primitives, Algorithms, and Utilities

The geo crate provides a number of 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.

Please refer to the documentation for a complete list.

Example

use geo::{Polygon, LineString};
use geo::convexhull::ConvexHull;

// An L shape
let coords = vec![(0.0, 0.0), (4.0, 0.0), (4.0, 1.0), (1.0, 1.0), (1.0, 4.0), (0.0, 4.0), (0.0, 0.0)];
// conversions to geo types are provided from several kinds of coordinate sequences
let poly = Polygon::new(coords.into(), vec![]);

// uses the QuickHull algorithm to calculate the polygon's convex hull
let hull = poly.convex_hull();
let correct = vec![(0.0, 0.0), (0.0, 4.0), (1.0, 4.0), (4.0, 1.0), (4.0, 0.0), (0.0, 0.0)]
assert_eq!(hull.exterior, correct.into());
