ee.Geometry.Rectangle.toGeoJSON

  • The toGeoJSON() method converts an Earth Engine Geometry object, such as a Rectangle, into a GeoJSON representation.

  • This functionality is available in both JavaScript and Python environments within the Earth Engine code editor and Google Colab, respectively.

  • The returned GeoJSON object can then be used for further processing or visualization, for instance, displaying the geometry on a map.

  • Examples demonstrate how to define a rectangle, apply the toGeoJSON() method, print the result, and add it as a layer to an interactive map using the geemap library in Python or the Map object in JavaScript.

Returns a GeoJSON representation of the geometry.

UsageReturns

Examples

Code Editor (JavaScript)

// Define a Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);

// Apply the toGeoJSON method to the Rectangle object.
var rectangleToGeoJSON = rectangle.toGeoJSON();

// Print the result to the console.
print('rectangle.toGeoJSON(...) =', rectangleToGeoJSON);

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

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 toGeoJSON method to the Rectangle object.
rectangle_to_geojson = rectangle.toGeoJSON()

# Print the result.
display('rectangle.toGeoJSON(...) =', rectangle_to_geojson)

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