# IsolineShapeGeometry
<a name="API_IsolineShapeGeometry"></a>

Represents the shape of a reachable area. The geometry can be provided either as coordinate pairs (`Polygon`) or in encoded format (`PolylinePolygon`), matching the format specified in the request.

 ** Polygon **   <a name="location-Type-IsolineShapeGeometry-Polygon"></a>
A series of coordinate rings defining the reachable area when Simple geometry format is requested. Each ring is a list of `[longitude, latitude]` coordinate pairs. The first ring defines the outer boundary; subsequent rings define holes representing unreachable areas.  
Polygon and PolylinePolygon are mutually exclusive properties.
Type: Array of arrays of arrays of doubles  
Array Members: Minimum number of 1 item.  
Array Members: Minimum number of 4 items.  
Array Members: Fixed number of 2 items.  
Required: No

 ** PolylinePolygon **   <a name="location-Type-IsolineShapeGeometry-PolylinePolygon"></a>
An encoded representation of the reachable area when FlexiblePolyline geometry format is requested. Provides a compact representation suitable for transmission and storage. The first string defines the outer boundary; subsequent strings define holes representing unreachable areas. For more information on polyline encoding, see [https://github.com/aws-geospatial/polyline](https://github.com/aws-geospatial/polyline).  
Polygon and PolylinePolygon are mutually exclusive properties.
Type: Array of strings  
Array Members: Minimum number of 1 item.  
Length Constraints: Minimum length of 1.  
Required: No
