# Geographic dissolve

The Geographic dissolve step allows you to aggregate or merge geographical entities into larger units. It's particularly useful for simplifying complex geographical data or creating higher-level geographical representations, such as grouping countries into continents.

### Step parameters

* `Group rows by...`: The column(s) by which data to dissolve should be grouped
* `And aggregate...`: Optional. The column(s) you wish to aggregate in addition to the column containing geo data. See [`aggregate`](https://weaverbird.toucantoco.dev/docs/aggregate/) step for details on the format.

### Example

**Input**

<figure><img src="/files/ZeSMLVieQjR0s3poOPTp" alt=""><figcaption><p>Geo - dissolve input</p></figcaption></figure>

**Configuration**

```json
{
    "groups": ["name"],
    "include_nulls": false,
    "aggregations": [
        {
            "aggfunction": "distinct",
            "columns": ["coffee shop"],
        }
    ]
}
```

**Output**
