### Mutation
Use this mutation to import a template specifically designed to work with the `GroundValueChecker` type. This template uses a Zabbix Script item to dynamically calculate a BBOX around the host's coordinates and fetch ground values from the NRW BORIS WMS service.

```graphql
mutation ImportGroundValueTemplate($templates: [CreateTemplate!]!) {
  importTemplates(templates: $templates) {
    host
    templateid
    message
    error {
      message
      code
    }
  }
}
```

### Variables
The following variables define the `GROUND_VALUE_CHECKER` template. It uses the host's user macros (`{$LAT}` and `{$LON}`) to fetch localized ground value data.
