ee.Feature
Features can be constructed from one of the following arguments plus an optional dictionary of properties:
- 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
// 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);
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
# Create the simplest possible feature.
display(ee.Feature(None)) # Empty feature
# Demonstrate how to set a feature's id.
display(ee.Feature(None, {'id': 'yada'}).id()) # None
display(ee.Feature(None, {'system:index': 'abc123'}).id()) # abc123
# The simplest possible feature with a geometry.
feature = ee.Feature(ee.Geometry.Point([-114.318, 38.985]))
m = geemap.Map()
m.add_layer(feature)
m.center_object(feature, 10)
m
