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>
