Description
The multidimensional resource returns multidimensional information for the service. This resource is supported if the has property of the service is true.
Common data sources for multidimensional image services are mosaic datasets created from netCDF, GRIB, and HDF data.
Request parameters
| Parameter | Details |
|---|---|
| Returns the dimension values of an image service. Values: |
| Added at 10.9. This parameter specifies the rendering rule for how the requested image service will be processed. The response is the multidimensional information that reflects a custom processing as defined by the rendering rule. See raster function JSON objects for the syntax and examples. |

The response format. The default response format is Values: |
Example usage
The following is a sample request URL that demonstrates returning the multidimensional information for an image service:
https://machine.domain.com/arcgis/rest/services/MyService/ImageServer/multidimensionalInfo?f=pjsonJSON Response syntax
The response contains dimensions for each variable in the service.
