# 46. Mutation: 多層「ZonesMap」を非同期生成

複数のレイヤーに基づいて「ZonesMap」を非同期で生成します。

{% hint style="info" %}
非同期アプローチは処理するタスク（Generate「generateVectorAnalysisMap」）を生成し、処理が完了次第サブスクリプションが受信されます。
{% endhint %}

属性 `dataLayers` 結果の「ZonesMap」で利用するための各データレイヤーごとの必要な情報を含みます。属性 `係数` は記号を表し、 **重み** データレイヤーの。

{% code overflow="wrap" lineNumbers="true" %}

```graphql
