ee.Geometry.LineString.toGeoJSON

AI-generated Key Takeaways

• The toGeoJSON() function returns a GeoJSON representation of a given Earth Engine geometry, such as a LineString.

• This function can be used with any Earth Engine Geometry object, and it takes no arguments besides the Geometry instance itself.

• Examples are provided in both JavaScript and Python (using geemap) to showcase the function's usage and display the resulting GeoJSON.

Returns a GeoJSON representation of the geometry.

Usage	Returns
LineString.toGeoJSON()	GeoJSONGeometry

Argument	Type	Details
this: geometry	Geometry	The Geometry instance.

Examples

Code Editor (JavaScript)

// Define a LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);

// Apply the toGeoJSON method to the LineString object.
var lineStringToGeoJSON = lineString.toGeoJSON();

// Print the result to the console.
print('lineString.toGeoJSON(...) =', lineStringToGeoJSON);

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

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 LineString object.
linestring = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]])

# Apply the toGeoJSON method to the LineString object.
linestring_to_geojson = linestring.toGeoJSON()

# Print the result.
display('linestring.toGeoJSON(...) =', linestring_to_geojson)

# Display relevant geometries on the map.
