ee.Geometry.distance

  • TheGeometry.distance method returns the minimum distance between two geometries as a Float.

  • The method takesright (the second geometry), optionalmaxError, optionalproj for projection, and optionalspherical parameters.

  • ThemaxError parameter specifies the maximum tolerated error during reprojection.

  • Theproj parameter specifies the projection to use; otherwise, it defaults to a spherical coordinate system.

  • Thespherical parameter determines whether calculations are done on a unit sphere or elliptically, and it is ignored ifproj is specified.

 Returns the minimum distance between two geometries.

UsageReturns
Geometry.distance(right,maxError,proj,spherical)Float
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.
sphericalBoolean, default: falseIf true, the calculation will be done on the unit sphere. If false, the calculation will be elliptical, taking earth flattening into account. Ignored if proj is specified. Default is false.
