ee.Geometry.Rectangle.centroid
Stay organized with collections
Save and categorize content based on your preferences.
Returns a point at the center of the highest-dimension components of the geometry. Lower-dimensional components are ignored, so the centroid of a geometry containing two polygons, three lines and a point is equivalent to the centroid of a geometry containing just the two polygons.
Usage Returns Rectangle. centroid (maxError , proj )
Geometry
Argument Type Details this: geometry
Geometry Calculates the centroid of this geometry. 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 this projection. Otherwise it will be in WGS84.
Examples
Code Editor (JavaScript)
// Define a Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);
// Apply the centroid method to the Rectangle object.
var rectangleCentroid = rectangle.centroid({'maxError': 1});
// Print the result to the console.
print('rectangle.centroid(...) =', rectangleCentroid);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(rectangle,
{'color': 'black'},
'Geometry [black]: rectangle');
Map.addLayer(rectangleCentroid,
{'color': 'red'},
'Result [red]: rectangle.centroid');
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 Rectangle object.
rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43)
# Apply the centroid method to the Rectangle object.
rectangle_centroid = rectangle.centroid(maxError=1)
# Print the result.
display('rectangle.centroid(...) =', rectangle_centroid)
# Display relevant geometries on the map.
m = geemap.Map()
m.set_center(-122.085, 37.422, 15)
