area method

double area(
  1. Map object
)

Returns the projected planar area (typically in square pixels) for the specified GeoJSON object.

Point, MultiPoint, LineString and MultiLineString geometries have zero area. For Polygon and MultiPolygon geometries, this method first computes the area of the exterior ring, and then subtracts the area of any interior holes. This method observes any clipping performed by the transform.

Implementation

double area(Map object) => planar.area(object, _transformStream);
