getMapStyleDescriptor   
  This operation is no longer current and may be deprecated in the future. We recommend upgrading to GetStyleDescriptor unless you require Grab data.
- GetMapStyleDescriptoris part of a previous Amazon Location Service Maps API (version 1) which has been superseded by a more intuitive, powerful, and complete API (version 2).
- The version 2 - GetStyleDescriptoroperation gives a better user experience and is compatible with the remainder of the V2 Maps API.
- If you are using an AWS SDK or the AWS CLI, note that the Maps API version 2 is found under - geo-mapsor- geo_maps, not under- location.
- Since - Grabis not yet fully supported in Maps API version 2, we recommend you continue using API version 1 when using- Grab.
- Start your version 2 API journey with the Maps V2 API Reference or the Developer Guide. Retrieves the map style descriptor from a map resource. 
The style descriptor contains specifications on how features render on a map. For example, what data to display, what order to display the data in, and the style for the data. Style descriptors follow the Mapbox Style Specification.
