ee.Feature
Page Summary
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 |
|---|---|
ee.Feature(geometry,properties) | Feature |
| Argument | Type | Details |
|---|---|---|
geometry | ComputedObject|Feature|Geometry|Object | A geometry or feature. |
properties | 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());// nullprint(ee.Feature(null,{'system:index':'abc123'}).id());// abc123// The simplest possible feature with a geometry.varfeature=ee.Feature(ee.Geometry.Point([-114.318,38.985]));Map.addLayer(feature);Map.centerObject(feature,10);
