ee.Geometry.MultiLineString.cutLines

本页内容
Examples

Converts LineString, MultiLineString, and LinearRing geometries into a MultiLineString by cutting them into parts no longer than the given distance along their length. All other geometry types will be converted to an empty MultiLineString.

Usage	Returns
`MultiLineString.cutLines(distances, maxError, proj)`	Geometry

Argument	Type	Details
this: `geometry`	Geometry	Cuts the lines of this geometry.
`distances`	List	Distances along each LineString to cut the line into separate pieces, measured in units of the given proj, or meters if proj is unspecified.
`maxError`	ErrorMargin, default: null	The maximum amount of error tolerated when performing any necessary reprojection.
`proj`	Projection, default: null	Projection of the result and distance measurements, or EPSG:4326 if unspecified.

// Apply the cutLines method to the MultiLineString object.

// Print the result to the console.

// Display relevant geometries on the map.
