ee.Geometry.MultiPoint.projection

  • The projection() method returns the projection of a given geometry, specifically a MultiPoint in this case.

  • This method is useful for obtaining the coordinate reference system (CRS) information associated with the geometry.

  • Usage involves calling projection() on a geometry object, like a MultiPoint, which returns a Projection object.

  • Example code snippets demonstrate using projection() in both JavaScript and Python within the Earth Engine environment.

 Returns the projection of the geometry.

Examples

Code Editor (JavaScript)

// Define a MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);

// Apply the projection method to the MultiPoint object.
var multiPointProjection = multiPoint.projection();

// Print the result to the console.
print('multiPoint.projection(...) =', multiPointProjection);

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

Python setup

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

Colab (Python)

# Define a MultiPoint object.
multipoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]])

# Apply the projection method to the MultiPoint object.
multipoint_projection = multipoint.projection()

# Print the result.
display('multipoint.projection(...) =', multipoint_projection)

# Display relevant geometries on the map.
m = geemap.Map()
