ee.Geometry.Point.length

Returns the length of the linear parts of the geometry. Polygonal parts are ignored. The length of multi geometries is the sum of the lengths of their components.

UsageReturns
Point.length(maxError, proj)Float
ArgumentTypeDetails
this: geometryGeometryThe input geometry.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullIf specified, the result will be in the units of the coordinate system of this projection. Otherwise it will be in meters.

Examples

Code Editor (JavaScript)

// Define a Point object.
var point = ee.Geometry.Point(-122.082, 37.42);

// Apply the length method to the Point object.
var pointLength = point.length();

// Print the result to the console.
print('point.length(...) =', pointLength);

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

Python setup

See the Python Environment page for information on the Python API and using geemap for interactive development.

import ee
import geemap.core as geemap

Colab (Python)

# Define a Point object.
point = ee.Geometry.Point(-122.082, 37.42)

# Apply the length method to the Point object.
point_length = point.length()

# Print the result.
display('point.length(...) =', point_length)

# Display relevant geometries on the map.
m = geemap.Map()
m.set_center(-122.085, 37.422, 15)
m.add_layer(point, {'color': 'black'}, 'Geometry [black]: point')
