Google Maps could be a net mapping service developed by Google. It offers satellite imagination, street maps, 360° broad views of streets (Street View), time period traffic conditions (Google Traffic), and route designing for traveling by foot, car, bicycle (in beta), or public transportation.

Google Maps began as a C++ desktop program at wherever a pair of Technologies. In October 2004, the corporate was noninheritable  by Google, that reborn it into an internet application. when extra acquisitions of a geospatial information mental image company and a realtime traffic instrument, Google Maps was launched in Gregorian calendar month 2005. The service's forepart utilizes JavaScript, XML, and Ajax. Google Maps offers associate API that permits maps to be embedded on third-party websites, and offers a locater for urban businesses and different organizations in varied countries round the world. Google geographer allowed users to collaboratively expand and update the service's mapping worldwide however was discontinued  from March 2017. However, crowdsourced contributions to Google Maps weren't discontinued  because the company proclaimed those options are transferred to the Google native Guides program.

Google Maps' satellite read could be a "top-down" or "birds eye" view; most of the high-resolution imagination of cities is aerial photography taken from craft flying at 800 to one,500 feet (240 to 460 m), whereas most different imagination is from satellites.abundant of the offered satellite imagination isn't any over 3 years recent and is updated on a daily basis.Google Maps used a variant of the Mercator projection, and thus cannot accurately show areas round the poles. but, in August 2018, the desktop version of Google Maps was updated to point out a 3D globe.


The current redesigned version of the desktop application was created offered in 2013, aboard the "classic" (pre-2013) version. Google Maps for robot and iOS devices was discharged in September 2008 and options GPS turn-by-turn navigation at the side of dedicated parking help options. In August 2013, it had been determined to be the world's hottest app for smartphones, with over fifty four of worldwide smartphone house owners mistreatment it a minimum of once.

In 2012, Google reported  having over seven,100 staff and contractors directly operating in mapping.

Google Maps provides a route planner, permitting users to seek out offered directions through driving, public transportation, walking, or biking. Google has partnered globally with over 800 public transportation suppliers to adopt General Transit Feed Specification (GTFS), creating the information offered to third parties. Google Traffic offers traffic information in time period, employing a coloured map overlay to show the speed of vehicles on explicit roads. Crowdsourcing is employed to get the GPS-determined locations of an outsized range of wireless telephone users, from that live traffic maps area unit created.

Implementation

Like several different Google net applications, Google Maps uses JavaScript extensively. because the user drags the map, the grid squares area unit downloaded from the server and inserted into the page. once a user searches for a business, the results area unit downloaded within the background for insertion into the aspect panel and map; the page isn't reloaded. Locations area unit drawn dynamically by positioning a red pin (composed of many partly clear PNGs) on prime of the map pictures. A hidden IFrame with type submission is employed as a result of it preserves browser history. the positioning conjointly uses JSON for information transfer instead of XML, for performance reasons. These techniques each fall into the broad Ajax umbrella. The result's termed a slick map and is enforced elsewhere in comes like OpenLayers.[citation needed]

In October 2011, Google proclaimed MapsGL, a WebGL version of Maps with higher renderings and power tool transitions.

The version of Google Street read for traditional Google Maps needs Adobe Flash.

Google Indoor Maps uses JPG, .PNG, .PDF, .BMP, or .GIF, for architectural plan.

Extensibility and customization

As Google Maps is coded nearly entirely in JavaScript and XML, some finish users have reverse-engineered the tool and created client-side scripts and server-side hooks that allowed a user or web site to introduce dilated or made-to-order options into the Google Maps interface.

Using the core engine and also the map/satellite pictures hosted by Google, such tools will introduce custom location icons, location coordinates and information, and even custom map image sources into the Google Maps interface. The script-insertion tool Greasemonkey provides an outsized range of client-side scripts to customise Google Maps information.

Combinations with picture sharing websites, like Flickr, area unit accustomed produce "memory maps".[clarification required What area unit memory maps?] mistreatment copies of the hole satellite photos, users have taken advantage of image annotation options to supply personal histories and data relating to explicit points of the realm.

Google Maps API
After the success of reverse-engineered mashups like chicagocrime.org and housingmaps.com, Google launched the Google Maps API in Gregorian calendar month 2005[19] to permit developers to integrate Google Maps into their websites. it had been a free service that did not need associate API key till Gregorian calendar month 2018 (changes went into result on Gregorian calendar month 16), once it had been proclaimed that associate API key connected to a Google Cloud account with charge enabled would be needed to access the API. The API presently doesn't contain ads, however Google states within their terms of use that they reserve the correct to show ads in the future.

By mistreatment the Google Maps API, it's doable to plant Google Maps into associate external web site, on to that site-specific information are often overlaid.though at the start solely a JavaScript API, the Maps API was dilated to incorporate associate API for Adobe Flash applications (but this has been deprecated), a service for retrieving static map pictures, and net services for acting geocoding, generating driving directions, and getting elevation profiles. Over 1,000,000[23] internet sites use the Google Maps API, creating it the foremost heavily used net application development API.

The Google Maps API is free for industrial use, as long as the positioning on that it's being employed is publically accessible and doesn't charge for access, and isn't generating over twenty five,000 map accesses each day.Sites that don't meet these necessities can buy the Google Maps API for Business.

The success of the Google Maps API has spawned variety of competitive  alternatives, together with the HERE Maps API, Bing Maps Platform, Leaflet and OpenLayers via self-hosting.[citation needed]. The Yahoo! Maps API is within the method of being clean up.

In September 2011, Google proclaimed it might discontinue variety of its merchandise, together with Google Maps API for Flash.

Google Maps for robot and iOS devices
Main article: Google Maps (app)
Google Maps is offered as a mobile app for the robot and iOS mobile operational systems.

The robot app was initial discharged in September 2008, tho' the GPS-localization feature had been in testing on cellphones since 2007Google Maps was Apple's answer for its mapping service on iOS till the discharge of iOS half-dozen in September 2012, at that purpose it had been replaced by Apple Maps,with Google emotional its own Google Maps standalone app on the iOS platform the subsequent Dec.

The Google Maps apps on robot and iOS have several options in common, together with turn-by-turn navigation, street read, and transportation system info. Updates in Gregorian calendar month 2012 and will 2014 enabled practicality to let users save sure map regions for offline access,whereas updates in 2017 have enclosed options to actively facilitate U.S. users realize offered parking spots in cities, and to relinquish Indian users a two-wheeler transportation mode for improved traffic accessibility.

Google Maps on iOS received vital praise when its standalone app unleash in Dec 2012, with critics highlight its elaborated info and style as positives. but, the apps have received criticism over privacy considerations, notably a location history pursuit page that provides "step by step" location work, with privacy advocates advising users to disable the feature, which associate April 2014 privacy about-face enabled Google to possess a unified login throughout its iOS apps, serving to it establish every user's interactions among every app.

Google Maps and Street read parameters

A sharable parametrized split read. within the bottom 0.5 the road Maps is shown, whereas within the prime 0.5 the road read is shown. A user will zoom-in and out either of them severally of the zoom level of every. This feature is merely offered in classic Google Maps, and is missing within the redesigned new Maps.

The redesigned version's read with a fixed-zoom level of the little (Street or Satellite) summary that a user can't zoom-in or out.
In Google Maps, computer address parameters area unit typically data-driven in their limits and also the computer program given by the net could or might not replicate those limits. specially, the zoom level (denoted by the z parameter) supported varies.[54] In less inhabited regions, the supported zoom levels may stop at around eighteen. In earlier versions of the API, specifying these higher values may end in no image being displayed. In Western cities, the supported zoom level typically stops at regarding twenty. In some isolated cases, the information supports up to twenty three or bigger, as in these elephants or this read of individuals at a well in Chad, Africa. completely different versions of the API and net interfaces could or might not absolutely support these higher levels.

As of October 2010, the Google map viewer updates its zoom bar to permit the user to zoom all the means once focused over areas that support higher zoom levels. within the classic version, made-to-order (split) Map and Street read views are often saved as parametrized computer address links and shared by users. within the 2013 redesigned version, a way smaller summary window becomes interactive upon hovering it and permits a user to vary the placement and rotate the road read and save a parametrized read, as well.
