ee.Geometry.Point.area

  • The area method returns the area of a geometry, with points and line strings having an area of 0 and multi geometries having an area equal to the sum of their components.

  • The method takes optional maxError and proj arguments to specify the maximum tolerated error during reprojection and the desired output projection, respectively.

  • The method returns a Float value representing the calculated area.

 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).

UsageReturns
Point.area(maxError, proj)Float
ArgumentTypeDetails
this: geometryGeometryThe geometry input.
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 square meters.

Examples

Code Editor (JavaScript)

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

// Apply the area method to the Point object.
var pointArea = point.area({'maxError': 1});

// Print the result to the console.
print('point.area(...) =', pointArea);

// 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 area method to the Point object.
point_area = point.area(maxError=1)

# Print the result.
display('point.area(...) =', point_area)

# 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')
