Generate "ZonesMap" for the "Field".

{% hint style="info" %}
Execution time is different (from 4sec till 5mins), it depends on the number of images and field area to process, and the Subscription will be received after the successful generation of "ZonesMap".
{% endhint %}

{% hint style="danger" %}
We recommend using an **asynchronous** approach to generate ZonesMaps
