Required. The type of the pollen heatmap. Defines the combination of pollen type and index that the map will graphically represent.
zoom
integer
Required. The map's zoom level. Defines how large or small the contents of a map appear in a map view.
Zoom level 0 is the entire world in a single tile.
Zoom level 1 is the entire world in 4 tiles.
Zoom level 2 is the entire world in 16 tiles.
Zoom level 16 is the entire world in 65,536 tiles.
Allowed values: 0-16
x
integer
Required. Defines the east-west point in the requested tile.
y
integer
Required. Defines the north-south point in the requested tile.
Request body
The request body must be empty.
Response body
Message that represents an arbitrary HTTP body. It should only be used for payload formats that can't be represented as JSON, such as raw binary or an HTML page.
This message can be used both in streaming and non-streaming API methods in the request as well as the response.
It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body.
Example:
message GetResourceRequest {
// A unique request id.
string request_id = 1;
// The raw HTTP body is bound to this field.
google.api.HttpBody http_body = 2;
}
service ResourceService {
rpc GetResource(GetResourceRequest)
returns (google.api.HttpBody);
rpc UpdateResource(google.api.HttpBody)
returns (google.protobuf.Empty);
}
Application specific response metadata. Must be set in the first response for streaming APIs.
An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.
