```go theme={"system"}
func UnmarshalDatapoint(
    descriptor *datasets.DatapointDescriptor,
    data []byte,
) (map[string]any, error)
```

Decode a raw protobuf datapoint into a JSON-like map using a dataset descriptor.

## Parameters

<ParamField path="descriptor" type="*datasets.DatapointDescriptor" required>
  The descriptor returned by [`NewDatapointDescriptor`](/api-reference/go/datasets/NewDatapointDescriptor).
</ParamField>

<ParamField path="data" type="[]byte" required>
  The raw protobuf datapoint bytes returned by a datapoint query.
</ParamField>

## Returns

A map of datapoint fields, or an error if the raw datapoint cannot be decoded.

<RequestExample>
  ```go Go theme={"system"}
  descriptor, err := datasets.NewDatapointDescriptor(dataset)
  if err != nil {
      return err
  }

  for data, err := range client.Datapoints.Query(ctx,
      dataset.ID,
      datasets.WithTemporalExtent(queryInterval),
  ) {
      if err != nil {
          return err
      }

      datapoint, err := datasets.UnmarshalDatapoint(descriptor, data)
      if err != nil {
          return err
      }
      fmt.Println(datapoint["id"])
  }
  ```
