Note: This feature is highly experimental.

In any of the data specs, there is now the option of providing spatial dimensions. For example, for a JSON data spec, spatial dimensions can be specified as follows:

<code>
{
    "type": "JSON",
    "dimensions": <some_dims>,
    "spatialDimensions": [
        {
            "dimName": "coordinates",
            "dims": ["lat", "long"]
        },
        ...
    ]
}
</code>
