# ee.data.computeFeatures (Python only)

<br />

Computes a list of features by applying a computation to features.

<br />

Returns:
A list of GeoJSON features reprojected to EPSG:4326 with planar edges.

| Usage | Returns |
|---|---|
| `ee.data.computeFeatures(params)` | List |

| Argument | Type | Details |
|---|---|---|
| `params` | Object | An object containing parameters with the following possible values: `expression` - The expression to compute. `pageSize` - The maximum number of results per page. The server may return fewer images than requested. If unspecified, the page size default is 1000 results per page. `fileFormat` - If present, specifies an output format for the tabular data. The function makes a network request for each page until the entire table has been fetched. The number of fetches depends on the number of rows in the table and `pageSize`. `pageToken` is ignored. Supported formats are: `PANDAS_DATAFRAME` for a Pandas DataFrame and `GEOPANDAS_GEODATAFRAME` for a GeoPandas GeoDataFrame. `pageToken` - A token identifying a page of results the server should return. `workloadTag` - User supplied tag to track this computation. |

## Examples

Python setup

See the [Python Environment](https://developers.google.com/earth-engine/guides/python_install) page for information on the Python API and using
`geemap` for interactive development.

```python
import ee
import geemap.core as geemap
```

### Colab (Python)

```python
# Region of interest.
pt = ee.Geometry.Point([-122.0679107870136, 36.983302098145906])
# Imagery of interest.
images = (ee.ImageCollection('LANDSAT/LC08/C02/T1_L2')
          .filterBounds(pt).filterDate('2021-01-01', '2021-12-31'))


def point_overlay(image):
  """Extracts image band values for pixel-point intersection."""
  return ee.Feature(pt, image.reduceRegion('first', pt, 30))

# Convert an ImageCollection to a FeatureCollection.
features = images.map(point_overlay)

features_dict = ee.data.computeFeatures({'expression': features})

display(features_dict)
# Do something with the features...
