ee.Geometry.MultiLineString.area

本页内容
Examples

Returns the area of the geometry. Area of points and line strings is 0 and the area of multi geometries is the sum of the areas of their components (intersecting areas are counted multiple times).

Usage	Returns
`MultiLineString.area(maxError, proj)`	Float

Argument	Type	Details
this: `geometry`	Geometry	The geometry input.
`maxError`	ErrorMargin, default: null	The maximum amount of error tolerated when performing any necessary reprojection.
`proj`	Projection, default: null	If specified, the result will be in the units of the coordinate system of this projection. Otherwise it will be in square meters.

// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
   [[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
    [[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);

// Apply the area method to the MultiLineString object.
var multiLineStringArea = multiLineString.area({'maxError': 1});

// Print the result to the console.
print('multiLineString.area(...) =', multiLineStringArea);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiLineString,
             {'color': 'black'},
             'Geometry [black]: multiLineString');
