Returns true if and only if one geometry contains the other.
Usage
Returns
LinearRing.contains(right, maxError, proj)
Boolean
Argument
Type
Details
this: left
Geometry
The geometry used as the left operand of the operation.
right
Geometry
The geometry used as the right operand of the operation.
maxError
ErrorMargin, default: null
The maximum amount of error tolerated when performing any necessary reprojection.
proj
Projection, default: null
The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere.
