# @ohos.geoLocationManager (Geolocation Manager) (System API) The **geoLocationManager** module provides location services such as Global Navigation Satellite System (GNSS)-based positioning, network positioning, geofencing, as well as geocoding and reverse geocoding. > **NOTE** > > The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version. > This topic describes only system APIs provided by the module. For details about its public APIs, see [@ohos.geoLocationManager (Geolocation Manager)](js-apis-geoLocationManager.md). > This module supports only the WGS-84 coordinate system. ## Applying for Permissions Before using basic location capabilities, check whether your application has been granted the permission to access the device location information. If not, your application needs to obtain the permission from the user as described below. The system provides the following location permissions: - ohos.permission.LOCATION - ohos.permission.APPROXIMATELY_LOCATION - ohos.permission.LOCATION_IN_BACKGROUND If your application needs to access the device location information, it must first apply for required permissions. Specifically speaking: API versions earlier than 9: Apply for **ohos.permission.LOCATION**. API version 9 and later: Apply for **ohos.permission.APPROXIMATELY\_LOCATION**, or apply for **ohos.permission.APPROXIMATELY\_LOCATION** and **ohos.permission.LOCATION**. Note that **ohos.permission.LOCATION** cannot be applied for separately. | API Version| Location Permission| Permission Application Result| Location Accuracy| | -------- | -------- | -------- | -------- | | Earlier than 9| ohos.permission.LOCATION | Success| Location accurate to meters| | 9 and later| ohos.permission.LOCATION | Failure| No location obtained| | 9 and later| ohos.permission.APPROXIMATELY_LOCATION | Success| Location accurate to 5 kilometers| | 9 and later| ohos.permission.APPROXIMATELY_LOCATION and ohos.permission.LOCATION| Success| Location accurate to meters| To access the device location information when running in the background, an application needs to request for a continuous task of the LOCATION type. In this way, the system continues to report device location information after your application moves to the background. For details about how to request for a continuous task, see [Continuous Task](../../task-management/continuous-task.md). A user can grant the **ohos.permission.LOCATION_IN_BACKGROUND** permission for an application on the setting page. For details, see [ohos.permission.LOCATION_IN_BACKGROUND](../../security/AccessToken/permissions-for-all.md#ohospermissionlocation_in_background). You can declare the required permission in your application's configuration file. For details, see [Requesting User Authorization](../../security/AccessToken/request-user-authorization.md). ## Modules to Import ```ts import { geoLocationManager } from '@kit.LocationKit'; ``` ## GeoAddress Geocoding address information. **System capability**: SystemCapability.Location.Location.Geocoder | Name| Type| Read Only| Optional| Description| | -------- | -------- | -------- | -------- | -------- | | isFromMock | Boolean | No| Yes| **true**: The geographic address is obtained from the mock reverse geocoding function.
