# Geolocation

The Geolocation module provides location services such as GNSS positioning, network positioning, geocoding, reverse geocoding, country code and geofencing.

> **NOTE**
> The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version.
> The APIs provided by this module are no longer maintained since API version 9. You are advised to use [geoLocationManager](js-apis-geoLocationManager.md) instead.

## 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|

If your application needs to access the device location information when running in the background, it must be configured to be able to run in the background and be granted the **ohos.permission.LOCATION_IN_BACKGROUND** permission. In this way, the system continues to report device location information after your application moves to the background.

You can declare the required permission in your application's configuration file. For details, see [Access Control (Permission) Development](../../security/accesstoken-guidelines.md).
