# PolylineQuality

A set of values that specify the quality of the polyline.

| Enums ||
|---|---|
| `POLYLINE_QUALITY_UNSPECIFIED` | No polyline quality preference specified. Defaults to `OVERVIEW`. |
| `HIGH_QUALITY` | Specifies a high-quality polyline - which is composed using more points than `OVERVIEW`, at the cost of increased response size. Use this value when you need more precision. |
| `OVERVIEW` | Specifies an overview polyline - which is composed using a small number of points. Use this value when displaying an overview of the route. Using this option has a lower request latency compared to using the `HIGH_QUALITY` option. |
