AI-generated Key Takeaways
-
Returns the minimum distance between a MultiPoint geometry and another geometry.
-
The distance calculation can be performed using a specified projection or in a spherical coordinate system (default, with distances in meters).
-
Optional parameters allow for specifying an error margin (
maxError
) for reprojection. -
The result is a float representing the minimum distance.
Usage | Returns |
---|---|
MultiPoint.distance(right, maxError, proj, spherical) | Float |
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. |
spherical | Boolean, default: false | If 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. |
