Any text field on your web page can be enhanced with the power of Google Maps auto-complete, giving you fast, accurate and easy address entry. Get deeper insight into how your website visitors interact with your maps with Analytics for Google Maps. Whether you need to show your users nearby bars, coffee shops, airports or supermarkets, you can provide a filtered list of places that are most relevant to your users. You can generate routes between up to 23 locations for driving, walking or cycling.

Up to 3 alternative routes are offered, and users can drag routes on the map to make changes. Routes can avoid toll roads or motorways, and travel time can be reduced by calculating the optimal order to visit each location.

If your application needs to determine travel time and distance quickly between many pairs of locations, you can use the Distance Matrix service of the Google Maps APIs. Google Maps APIs provide predictive travel time based on historical time of day and day of week data. The Google Maps APIs include ready-to-go drawing tools that enable your users to select areas, drop markers, and draw and edit shapes. The Google Maps APIs can deliver elevation profiles along any path, whether along a route or across a continent.

They even return depths underwater. Your mapping application could be crucial to your business so the Google Maps APIs ensure peace of mind by including hour technical support and a service-level agreement. You can switch any map to satellite view using the optional labels. The highest level of detail at a given location can be determined automatically, allowing you to show your users the best image possible. If you spot an error on the map, you can fix it using Google MapMaker and see the change reflected in your Google Maps APIs application within minutes.

Directions Requests

High-resolution screens are detected and the map is adjusted automatically to ensure that it remains perfectly crisp and clear. The Google Maps look and feel is familiar and trusted around the world, but if you need something a little different, the Google Maps APIs Key let you tailor the style of the map to your needs. You can simplify the map to draw more attention to your data, or restyle the map to fit in with the rest of your application. You can control the direction the panorama faces, respond to changes in the view triggered by your users and add interactive elements such as markers, pop-up windows or even your own panoramic images.

By default, directions are calculated as driving directions. The following travel modes are supported:. Note: Both walking and bicycling directions may sometimes not include clear pedestrian or bicycling paths, so these directions will return warnings in the returned result which you must display to the user. When calculating routes using the Directions API, you may specify waypoints to return a route that includes pass throughs or stopovers at intermediate locations.

You can add waypoints to driving, walking or bicycling directions but not transit directions. By default, the Directions service calculates a route using the waypoints in the order they are given. For efficiency and accuracy, use place ID's when possible. Unlike an address, ID's do not require the service to perform a search or an intermediate request for place details; therefore, performance is better.

Alternatively, you can supply an encoded set of points using the Encoded Polyline Algorithm. You will find an encoded set is useful for a large number of waypoints, because the URL is significantly shorter.

Introduction

All web services have a URL limit of characters. The example uses addresses:. For each waypoint in the request, the directions response appends an entry to the legs array to provide the details for stopovers on that leg of the journey. If you'd like to influence the route using waypoints without adding a stopover, add the prefix via: to the waypoint. Waypoints prefixed with via: will not add an entry to the legs array, but will route the journey through the waypoint.

The following URL modifies the previous request such that the journey is routed through Lexington without stopping:. The via: prefix is most effective when creating routes in response to the user dragging the waypoints on the map. Doing so allows the user to see how the final route may look in real-time and helps ensure that waypoints are placed in locations that are accessible to the Directions API.

By default, the Directions service calculates a route through the provided waypoints in their given order. Optionally, you may pass optimize:true as the first argument within the waypoints parameter to allow the Directions service to optimize the provided route by rearranging the waypoints in a more efficient order. This optimization is an application of the traveling salesperson problem. Travel time is the primary factor which is optimized, but other factors such as distance, number of turns and many more may be taken into account when deciding which route is the most efficient.

All waypoints must be stopovers for the Directions service to optimize their route. The following example calculates a road journey from Adelaide, South Australia to each of South Australia's main wine regions using route optimization. Inspection of the calculated route will indicate that calculation uses waypoints in the following waypoint order:. Directions may be calculated that adhere to certain restrictions. Restrictions are indicated by use of the avoid parameter, and an argument to that parameter indicating the restriction to avoid. The following restrictions are supported:.

It's possible to request a route that avoids any combination of tolls, highways and ferries by passing both restrictions to the avoid parameter.

Note: the addition of restrictions does not preclude routes that include the restricted feature; it simply biases the result to more favorable routes. Directions results contain text within distance fields that may be displayed to the user to indicate the distance of a particular "step" of the route.

By default, this text uses the unit system of the origin's country or region. For example, a route from "Chicago, IL" to "Toronto, ONT" will display results in miles, while the reverse route will display results in kilometers. You may override this unit system by setting one explicitly within the request's units parameter, passing one of the following values:. Note: this unit system setting only affects the text displayed within distance fields.

The distance fields also contain values which are always expressed in meters. You can set the Directions service to return results from a specific region by using the region parameter. This parameter takes a ccTLD country code top-level domain argument specifying the region bias.

You may utilize any domain in which the main Google Maps application has launched driving directions. For example, a directions request for "Toledo" to "Madrid" returns appropriate results when region is set to es and "Toledo" is then interpreted as the Spanish city:. A directions request for "Toledo" to "Madrid" sent without a region parameter does not return results, because "Toledo" is interpreted as the city in Ohio and not Spain:.

Directions responses are returned in the format indicated by the output flag within the URL request's path. The above example requests JSON output. It's also possible to request XML output. Because directions results can be quite verbose, repeated elements within the responses have been omitted for clarity.
