Detailed Description

Computes the distance between a point and a geometry (which may be a collection containing any type of geometry).

Also computes the pair of points containing the input point and the nearest point on the geometry.

IndexedDistanceToPoint()

geos::algorithm::construct::IndexedDistanceToPoint::IndexedDistanceToPoint

(

const Geometry &

geom

)

Creates an instance to find the distance from points to a geometry.

Parameters

geom	the geometry to compute distances to

Member Function Documentation

distance()

double geos::algorithm::construct::IndexedDistanceToPoint::distance

(

const Point &

pt

)

Computes the distance from the base geometry to the given point.

Parameters

pt	the point to compute the distance to

Returns

the computed distance

nearestPoints()

std::unique_ptr<geom::CoordinateSequence> geos::algorithm::construct::IndexedDistanceToPoint::nearestPoints

(

const Point &

pt

)

Computes the nearest point on the geometry to the point.

The first location lies on the geometry, and the second location is the provided point.

Parameters

pt	the point to compute the nearest point for

Returns

the points that are nearest
