public interface DataQuery
Defines the properties of a collection of data, as a result of a query through a DataStore.
The scale parameter can be used by the DataStore as a hint about the quality or resolution of the data needed to view or operate with the data returned. As an example, it may use the scale to return only a representative subset of the data, or maybe to return Data with less detail, like a point or a line instead of a polygon.
