Stay organized with collections
Save and categorize content based on your preferences.
Returns the minimum distance between two geometries.
Usage Returns MultiPolygon. distance (right, maxError , proj )
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.
Examples
Code Editor (JavaScript)
// Define a MultiPolygon object.
var multiPolygon = ee.Geometry.MultiPolygon(
[[[[-122.092, 37.424],
[-122.086, 37.418],
[-122.079, 37.425],
[-122.085, 37.423]]],
[[[-122.081, 37.417],
[-122.086, 37.421],
[-122.089, 37.416]]]]);
// Define other inputs.
var inputGeom = ee.Geometry.Point(-122.090, 37.423);
// Apply the distance method to the MultiPolygon object.
var multiPolygonDistance = multiPolygon.distance({'right': inputGeom, 'maxError': 1});
// Print the result to the console.
print('multiPolygon.distance(...) =', multiPolygonDistance);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPolygon,
{'color': 'black'},
'Geometry [black]: multiPolygon');
Map.addLayer(inputGeom,
{'color': 'blue'},
'Parameter [blue]: inputGeom');
