Functions

stDistance(Expression g1, Expression g2, {Expression? useSpheroid}) → FunctionExpression
For geometry types returns the minimum 2D Cartesian (planar) distance between two geometries, in projected units (spatial ref units).
stDWithin(Expression g1, Expression g2, Expression tolerance, {Expression? useSpheroid}) → FunctionExpression
Returns true if the geometries are within a given distance.
