ee.Geometry.intersection

  • Theintersection method returns the shared area between two geometries.

  • It takes aright geometry and optionalmaxError andproj arguments.

  • Theright argument specifies the second geometry for the intersection operation.

  • ThemaxError argument defines the maximum acceptable error during reprojection.

  • Theproj argument specifies the projection in which to perform the intersection.

 Returns the intersection of the two geometries.

UsageReturns
Geometry.intersection(right,maxError,proj)Geometry
ArgumentTypeDetails
this:leftGeometryThe geometry used as the left operand of the operation.
rightGeometryThe geometry used as the right operand of the operation.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullThe 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.
