2. About Google map
Google Maps is a web mapping service developed
by Google. Google Maps began as a C++ desktop program designed by Lars and
Jens Eilstrup Rasmussen at Where 2 Technologies. In October 2004, the
company was acquired by Google, which converted it into a web application.
Google Maps' satellite view is a "top-down" or "birds
eye" view; most of the high-resolution imagery of cities is aerial photography
taken from aircraft flying at 800 to 1,500 feet (240 to 460 m), while most other
imagery is from satellites.

3. Directions
1. Google Maps provides a route planner, allowing users to find available
directions through driving, public transportation, walking, or biking.
2. A journey planner, trip planner, or route planner is a specialised search
engine used to find an optimal means of travelling between two or more
given locations, sometimes using more than one transport mode.
3. Searches may be optimised on different criteria, for example fastest,
shortest, least changes, cheapest.

4. Implementation
1. Like many other Google web applications, Google Maps uses JavaScript
extensively.
2. Locations are drawn dynamically by positioning a red pin on top of the map
images.
3. A hidden IFrame with form submission is used because it preserves browser
history.
4. The site also uses JSON for data transfer rather than XML, for performance
reasons.

5. Google Maps API
After the success of reverse-engineered mashups such as chicagocrime.org and
housingmaps.com, Google launched the Google Maps API in June 2005 to allow
developers to integrate Google Maps into their websites.
By using the Google Maps API, it is possible to embed Google Maps site into an
external website, on to which site specific data can be overlaid.
The Google Maps API is free for commercial use, provided that the site on which
it is being used is publicly accessible and does not charge for access, and is not
generating more than 25,000 map accesses a day.

6. Google maps for Android and iOS devices
Google Maps is available as a mobile app for the Android and iOS mobile
operating systems.
The Android app was first released in September 2008, though the GPS-
localization feature had been in testing on cell phones since 2007.
Google Maps was Apple's solution for its mapping service on iOS until the
release of iOS 6 in September 2012, at which point it was replaced by Apple
Maps, with Google releasing its own Google Maps standalone app on the iOS
platform the following December.

7. Google Maps and Street View parameters
In Google Maps, URL parameters are sometimes data-driven in their limits and
the user interface presented by the web may or may not reflect those limits.
As of October 2010, the Google map viewer updates its zoom bar to allow the
user to zoom all the way when centered over areas that support higher zoom
levels.
In the 2013 redesigned version, a much smaller overview window becomes
interactive upon hovering it and enables a user to change the location and rotate
the Street View and save a parameterized view, as well.

8. History
1. The application was first announced on the Google Blog on February 8,
2005, and was located at Google. It originally only supported users of
Internet Explorer and Mozilla web browsers.
2. Coverage of the area around Turin was added in time for the 2006 Winter
Olympics.
3. On January 29, 2007, Local Universal results were upgraded and more data
included in the main Google results page.
4. On November 15, 2017, Google announced a significant update to the
Google Maps formatting.
