34 |
* <p> |
|
35 |
* The scala parameter can be used by the DataStore as a hint about the quality |

|
37 |
* As an example, it may use the scala to return only a representative subset of |
|
38 |
* the data, or maybe to return Data with less detail, like a point or a line |
|
39 |
* instead of a polygon. |
