Use of the Google Maps API requires that you indicate whether your application is using a sensor (such as a GPS locator) to determine the user's location.

The Google Maps API uses the browser's preferred language setting when displaying textual information such as the names for controls, copyright notices, driving directions and labels on maps. In most cases, this is preferable; you usually do not wish to override the user's preferred language setting. However, if you wish to change the Maps API to ignore the browser's language setting and force it to display information in a particular language, you can specifying the language to use.

The Maps API serves map tiles and biases application behavior, by default, using the country of the host domain from which the API is loaded (which is the USA for maps.google.com). If you wish to alter your application to serve different map tiles or bias the application (such as biasing geocoding results towards the region), you can override this default behavior by adding a region parameter to the Maps API javascript code. The region parameter accepts Unicode region subtag identifiers which (generally) have a one-to-one mapping to country code Top-Level Domains (ccTLDs). Most Unicode region identifiers are identical to ISO 3166-1 codes, with some notable exceptions. For example, Great Britain's ccTLD is "uk" (corresponding to the domain .co.uk) while its region identifier is "GB." For example, to use a Maps API application localized to the United Kingdom, add this settings to the code-behind as shown below:

CopyC#

GoogleMap1.Region = "GB";
