ST_FrechetDistance()¶

Computes the discrete Frechet distance between two geometries.

Syntax¶

ST_FrechetDistance(geom1, geom2)

Arguments¶

Argument	Description
`geom1`	First GEOMETRY or GEOMETRY32 value.
`geom2`	Second value from the same geometry family.

Return Value¶

Returns FLOAT64 for GEOMETRY inputs and FLOAT32 for GEOMETRY32 inputs.

Usage Notes¶

Examples¶

DROP DATABASE IF EXISTS geo_operation_demo;
CREATE DATABASE geo_operation_demo;
USE geo_operation_demo;

SELECT ST_FrechetDistance(ST_GeomFromText('LINESTRING(0 0,10 0)'), ST_GeomFromText('LINESTRING(0 1,10 1)')) AS distance_value;

DROP DATABASE geo_operation_demo;
