AI-generated Key Takeaways
-
Features can be constructed from an ee.Geometry, a GeoJSON Geometry, a GeoJSON Feature, or a computed object.
-
An optional dictionary of properties can be included when constructing a Feature.
-
The
ee.Feature(geometry, properties)usage returns a Feature object. -
Examples demonstrate creating simple and empty features in JavaScript and Python, as well as setting a feature's ID and adding a feature with geometry to a map.
- An ee.Geometry.
- A GeoJSON Geometry.
- A GeoJSON Feature.
- A computed object: reinterpreted as a geometry if properties are specified, and as a feature if they aren't.
| Usage | Returns |

Object, optional | A dictionary of metadata properties. If the first parameter is a Feature (instead of a geometry), this is unused. |
Examples
Code Editor (JavaScript)
// Create the simplest possible feature. print ( ee . Feature ( null )); // Empty feature // Demonstrate how to set a feature's id. print ( ee . Feature ( null , { 'id' : 'yada' }). id ()); // null print ( ee . Feature ( null , { 'system:index' : 'abc123' }). id ()); // abc123 // The simplest possible feature with a geometry. var feature = ee . Feature ( ee . Geometry . Point ([ - 114.318 , 38.985 ])); Map . addLayer ( feature ); Map . centerObject ( feature , 10 );
