Suppose we implement the GET request on the unmarkedBlankRegions resource to return the BlankRegion[] field indicating the list of all unmarked blank regions, the structure of the BlankRegion[] field is as follows:
| Field | Type | Description |
| blankRegionId | String | The ID of the unmarked blank region. |
| center | Point2D | The center point for map display. |
| id | int | The ID of the geometric object. |
| markType | MarkType | The type of the marked blank region. NONE indicates the blank region is unmarked. |
| parts | int[] | The numbers of vertices contained by child objects of the geometric object. |
| points | Point2D[] | The array of 2D coordinates of vertices composing the geometric object. |
| style | Style | The style of the geometry object. |
| type | GeometryType | The type of the geometry object. |
The returned rjson format representation after implementing the GET request on the unmarkedBlankRegions resource http://localhost:8090/iserver/manager/tileservice/jobs/7d59376f-f47a-405b-9862-41ac160b8f23/blankregions/unmarked.rjson?scale=8.333333333333333e-7&fromIndex=0&toIndex=5 is as follows:

Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content. The meta-information includes the media-type, content-encoding, transfer-encoding, content-length, etc.
HEAD request can be used to check if the unmarkedBlankRegions resource exists, or if the unmarkedBlankRegions resource can be accessed by clients. It can also determine if the unmarkedBlankRegions resource supports an output format <format> if performed on a URI with .<format> included.
