Geospatial Primitives, Algorithms, and Utilities

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.

Please refer to the documentation for a complete list.

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


use geo::{line_string, polygon};
use geo::convex_hull::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: 0.0, y: 0.0),
    (x: 0.0, y: 4.0),
    (x: 1.0, y: 4.0),
    (x: 4.0, y: 1.0),
    (x: 4.0, y: 0.0),
    (x: 0.0, y: 0.0),
