## [MaxZoomService](https://developers.google.com/maps/documentation/javascript/reference/max-zoom.md.txt#MaxZoomService) class class `google.maps.MaxZoomService` library `"maps"` A service for obtaining the highest zoom level at which satellite imagery is available for a given location. ```javascript const {MaxZoomService} = await google.maps.importLibrary("maps"); ``` | ### Constructor || |---|---| | `MaxZoomService` | `MaxZoomService()` **Parameters:** None Creates a new instance of a `MaxZoomService` that can be used to send queries about the maximum zoom level available for satellite imagery. | | ### Methods || |---|---| | `getMaxZoomAtLatLng` | `getMaxZoomAtLatLng(latlng[, callback])` **Parameters:** - `latlng: LatLng|LatLngLiteral` - `callback: function(MaxZoomResult): void optional` **Return Value:** `Promise` Returns the maximum zoom level for which detailed imagery is available at a particular `LatLng` for the `satellite` map type. As this request is asynchronous, you must pass a `callback` function which will be executed upon completion of the request, being passed a `MaxZoomResult`. | ## [MaxZoomResult](https://developers.google.com/maps/documentation/javascript/reference/max-zoom.md.txt#MaxZoomResult) interface interface `google.maps.MaxZoomResult` A MaxZoom result in JSON format retrieved from the MaxZoomService. | ### Properties || |---|---| | `zoom` | **Type:** `number` The maximum zoom level found at the given `LatLng`. | | `status` optional | **Type:** `MaxZoomStatus optional` Status of the request. This property is only defined when using callbacks with `MaxZoomService.getMaxZoomAtLatLng` (it is not defined when using Promises). | ## [MaxZoomStatus](https://developers.google.com/maps/documentation/javascript/reference/max-zoom.md.txt#MaxZoomStatus) constants constants `google.maps.MaxZoomStatus` library `"maps"` The status returned by the `MaxZoomService` on the completion of a call to `getMaxZoomAtLatLng()`. Specify these by value, or by using the constant's name. For example, `'OK'` or `google.maps.MaxZoomStatus.OK`. These constants are also usable as strings. In TypeScript, the string literals are defined by the `MaxZoomStatusString` type. ```javascript const {MaxZoomStatus} = await google.maps.importLibrary("maps"); ``` | ### Constants || |---|---| | `ERROR` | An unknown error occurred. | | `OK` | The response contains a valid `MaxZoomResult`. |
