Features

Google Maps features a map that users can pan (by dragging the mouse) and zoom (by using the mouse wheel). In Computing, a mouse (plural mice, mouse devices, or mouses) Users may enter an address, intersection or general area to quickly find it on the map. An address is a Code and abstract concept expressing the fixed location of a home business or other building on the earth's surface In the field of Road transport, an intersection is a road junction where two or more Roads either meet or cross at grade (they are

Users can also search for businesses and attractions (for example, theatres, restaurants and hotels) in or near a given place. Theatre (or theater, see spelling differences) is the branch of the Performing arts defined by Bernard Beckerman as what "occurs when one A restaurant is a retail establishment that serves prepared Food to Customers. A hotel is an establishment that provides paid lodging usually on a short-term basis For example, a user can enter a query such as "Waffles in Ottawa" to find restaurants serving waffles in the city. A restaurant is a retail establishment that serves prepared Food to Customers.

Like many other map services, Google Maps can generate driving directions between any pair of locations in the United States and Canada, as well as many other countries. Navigation is the process of reading and controlling the movement of a craft or vehicle from one place to another It shows turn-by-turn instructions, an estimate of the trip time, and the distance between the two locations. Since July 2007, a user can drag any point on the route to another location to add a waypoint, and instantly see the revised route and length while dragging.

Starting November 21, 2007, users with a Google account can adjust the location of markers for businesses and other destinations. Events 164 BC - Judas Maccabaeus, son of Mattathias of the Hasmonean family restores the Temple in Jerusalem. Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. According to a video posted on "YouTube" "Sometimes a location can be a little off on a map and your friends can't find you. Now you can fix that. " If a user moves the marker by more than 200 meters, the change must go through moderation before it appears online.

Google Maps offers five viewing modes by default: Map (topographic and street map), Satellite (satellite and high-resolution aerial photographs), "Terrain" (geographic features in high relief with street overlay), Street View (ground level 360 degree view of certain streets, introduced on May 30, 2007), and Traffic' (traffic congestion maps).

The "link to this page" link on each Google Maps map targets a URL which can be used to find the location on the map at a later time. The latitude and longitude can be used as input to NASA World Wind or TerraServer-USA, which in some cases have higher-resolution imagery. WorldWind is a free Open source Virtual globe developed by NASA and open source community for use on Personal computers running Microsoft TerraServer-USA is a free online repository of Public domain Aerial imagery and Satellite imagery, formerly known as Microsoft TerraServer

Various governments have complained about the potential for terrorists to use the satellite images in planning attacks[1]. Google has blurred some areas for security (mostly in the United States), including the U.S. Naval Observatory area (where the official residence of the Vice President is located), and until recently, the United States Capitol and the White House (which formerly featured erased housetop). The United States Naval Observatory ( USNO) is one of the oldest Scientific agencies in the United States. The Vice President of the United States is the first person in the presidential line of succession, becoming the new President of the United States upon the death See also Executive Office of the President of the United States The White House, formerly known as the Executive Mansion, is the Official residence Other well-known government installations are visible including Area 51 in the Nevada desert. Area 51 is a nickname for a military base located in the southern portion of Nevada in the western United States Nevada ( is a state located in the western region of the United States of America.

With the introduction of an easily pannable and searchable mapping and satellite imagery tool, Google's mapping engine prompted a surge of interest in satellite imagery. Sites were established which feature satellite images of interesting natural and man-made landmarks, including such novelties as "large type" writing visible in the imagery, as well as famous stadia and unique earth formations.

Although Google uses the word "satellite", some of the high-resolution imagery is aerial photography taken from airplanes rather than from satellites. Aerial photography is the taking of Photographs of the ground from an elevated position [2]

Implementation

Like many other Google web applications, Google Maps uses JavaScript extensively. This article catalogs the coverage detail of Google Maps. Coverage details Localization JavaScript is a Scripting language most often used for Client-side web development As the user drags the map, the grid squares are downloaded from the server and inserted into the page. When a user searches for a business, the results are downloaded in the background for insertion into the side panel and map - the page is not reloaded. Locations are drawn dynamically by positioning a red pin (composed of several partially-transparent PNGs) on top of the map images. Portable Network Graphics ( PNG) is a bitmapped image format that employs Lossless data compression.

The technique of providing greater user-interactivity by performing asynchronous network requests with Javascript and XMLHttpRequest has recently become known as Ajax. XMLHttpRequest ( XHR) is an API that can be used by JavaScript and other Web browser Scripting languages to transfer XML Maps actually uses XmlHttpRequest sparingly, preferring a hidden IFrame with form submission because it preserves browser history. IFrame (from Inline Frame) is an HTML element which makes it possible to embed an HTML document inside another HTML document It also uses JSON for data transfer rather than XML, for performance reasons. JSON (ˈdʒeɪsɒn ie "Jason" short for JavaScript Object Notation, is a lightweight Computer data interchange format Don't change "Extensible" These techniques both fall under the broad Ajax umbrella.

The GIS (Geographic Information System) data used in Google Maps are provided by Tele Atlas, NAVTEQ, and MAPIT MSC, Malaysia,[3] while the small patches of high-resolution satellite imagery are largely provided by DigitalGlobe and its QuickBird satellite, with some imagery also from government sources. Tele Atlas is a Netherlands -based company founded in 1984 which delivers digital Maps and other dynamic content for Navigation and Location-based Navteq is a Chicago Illinois -based provider of Geographic Information Systems (GIS data and is a dominant company in providing the base electronic maps Satellite imagery consists of photographs of Earth or other planets made by means of Artificial satellites. DigitalGlobe, of Longmont Colorado, USA, is a privately held commercial vendor of space imagery and geospatial content and operator of civilian Specifications Sensors (137 μrad Panchromatic at Nadir (547 μrad Multispectral at Nadir The main global imagery base called NaturalVue was derived from Landsat 7 imagery by MDA Federal (formerly Earth Satellite Corporation). Earth Satellite Corporation (EarthSat was an early pioneer in the commercial utilization of the Earth observation satellite. This global image base provides the essential foundation for the entire application.

Extensibility and customization

As the Google Maps code is almost entirely JavaScript and XML, some end-users reverse-engineered the tool and produced client-side scripts and server-side hooks which allowed a user or website to introduce expanded or customised features into the Google Maps interface. JavaScript is a Scripting language most often used for Client-side web development Don't change "Extensible"

Using the core engine and the map/satellite images hosted by Google, such tools can introduce custom location icons, location coordinates and metadata, and even custom map image sources into the Google Maps interface. In Mathematics and its applications a coordinate system is a system for assigning an n - Tuple of Numbers or scalars to each point Metadata ( meta data, or sometimes metainformation) is "data about data" of any sort in any media The script-insertion tool Greasemonkey provides a large number of client-side scripts to customize Google Maps data, and the mymaps.com website provides an interface for easily adding your own set of locations and viewing them on Google Maps. Greasemonkey is a Mozilla Firefox extension that allows users to install scripts that make on-the-fly changes to most HTML-based

Combined with photo sharing websites such as Flickr, a phenomenon called "memory maps" emerged. Photo sharing is the publishing or transfer of a user's digital photos online thus enabling the user to share them with others (whether publicly or privately Flickr is an image and video hosting Website, Web services suite and Online community platform Using copies of the Keyhole satellite photos of their home towns or other favorite places, the users take advantage of image annotation features to provide personal histories and information regarding particular points of the area.

Google Maps API

Google created the Google Maps API to facilitate developers integrating Google Maps into their web sites with their own data points. It is a free service, which currently does not contain ads, but Google states in their terms of use[4] that they reserve the right to display ads in the future.

By using the Google Maps API you can embed the full Google Maps on an external web site. Start by creating an API Key,[5] it will be bound to the web site and directory you enter when creating the key. Creating your own map interface involves adding the Google JavaScript code to your page, and then using Javascript functions to add points to the map. JavaScript is a Scripting language most often used for Client-side web development

When the API first launched, it lacked the ability to geocode addresses, requiring you to manually add points in (latitude, longitude) format. Geocoding is the process of finding associated Geographic coordinates (often expressed as Latitude and Longitude) from other geographic data such This has since been rectified.

At the same time as the release of the Google Maps API, Yahoo! released their own Maps API. [6] Both were released to coincide with the O'Reilly Web 2. 0 Conference. Yahoo! Maps lacks international support, but included a geocoder in the first release.

As of October 2006, Google Gadgets' Google maps implementation is much easier to use with just the need of one line of script. Google Desktop is Desktop search software made by Google for Mac OS X, Linux, and Microsoft Windows. The drawback is that it is not as customizable as the full API.

In late 2006, Yahoo began a campaign to upgrade their maps, to compete better with Google Local and other online map companies. Several of the maps used in a survey were similar to Google maps.

Google Maps actively promotes the commercial use of their API. One of its earliest adopters at large scale are real estate mashup sites. Google's case study is about Nestoria, a property search engine in the UK and Spain. Nestoria is a vertical Search engine for real estate In terms of reach Nestoria is the 7th largest property web site in the UK and the 14th in Spain ( ComScore

Google Maps for Mobile

In late 2006, Google introduced a Java application called Google Maps for Mobile, which is intended to run on any Java based phone or mobile device. Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. Most, if not all, web based features are available from within the application. [7] On November 28th, 2007, Google Maps for Mobile 2. 0 was released. It introduced a GPS-like location service that does not require a GPS receiver. As of April 20, 2008, this service[8] is available for the following platforms:

Google Maps parameters

In Google Maps, the URL parameters may be tweaked to offer views and options not normally available through on-screen controls. The Sony Ericsson K800i, and its variant the Sony Ericsson K790, are mobile phones of their class from Sony Ericsson.

For instance, the maximum zoom level offered is normally 18, but if higher-resolution images are available, changing the z parameter, which sets the zoom level, will allow the user to access them, as in this view of elephants or this view of people at a well deep in Chad, Africa using the parameter z=23. Chad (Tchad تشاد Tshād) officially known as the Republic of Chad, is a Landlocked country in Central Africa.

A list of Google Maps parameters and their descriptions is available.

More Mars data sets with more recent data are available at Google Maps based interface at http://jmars.asu.edu/maps provided by Arizona State University

Google Ride Finder

Google launched an experimental Google Maps-based tool called Ride Finder, tapping into in-car GPS units for a selection of participating taxi and limousine services. Arizona State University ( ASU) is the largest public Research university in the United States under a single administration with total student Basic concept of GPS operation A GPS receiver calculates its position by carefully timing the signals sent by the constellation of GPS Satellites high above the Earth A taxicab, also taxi or cab, is a type of Public transport for a single passenger or small group of passengers typically for a non-shared ride A limousine (or limo) is a longer than normal Luxury car. The chassis may have been extended by the manufacturer or by an independent coach builder traditionally The tool displays the current location of all supported vehicles of the participating services in major US cities, including Chicago and San Francisco on a Google Maps street map. Chicago (ʃɪˈkɑːgoʊ is the largest City by population in the state of Illinois and the American Midwest of the United States. The City and County of San Francisco is the fourth most populous city

Google Transit

In December 2005, Google launched Google Transit. PortalCurrent events News collections and sources See WikipediaNews collections and sources. This is a web application (listed in Google Labs), that plans a trip using public transportation options. Google Labs is a website demonstrating new Google projects "that aren't quite ready for prime time" Google Transit launched with support for Portland, Oregon. Portland is a city located in the Northwestern United States, near the Confluence of the Willamette and Columbia rivers Information for Eugene, Oregon; Honolulu, Hawaii; Pittsburgh, Pennsylvania; Seattle, Washington; and Tampa, Florida was added on September 27 2006,[17] with more added since including adding cities in Canada, Europe, Japan and Perth.

Perth is the capital and largest city of the Australian state of Western Australia. The service calculates route, transit time and cost, and can compare the trip to one using a car.

Google My Maps

In April 2007, My Maps was a new feature added to Google's local search maps. April 2007 is the fourth month of that year It began on a Sunday and 30 days later ended on a Monday. My Maps lets users and businesses create their own map by positioning markers, polylines and polygons onto a map. The interface is a straightforward overlay on the map. A set of eighty-four pre-designed markers is available, ranging from bars and restaurants to webcam and earthquake symbols. Polyline and Polygon colour, width and opacity are selectable. Maps modified using My Maps can be saved for later viewing and made public (or marked as private), but cannot be printed.

Each element added to a My Map has an editable tag. This tag can contain text, rich text or HTML. Embeddable video and other content can be included within the HTML tag.

Upon the launch of My Maps there was no facility to embed the created maps into a webpage or blog. A few independent websites have now produced tools to let users embed maps and add further functionality to their maps. [18] This has been resolved with version 2. 78.

Google Street View

Main article: Google Street View

On May 25, 2007, Google released Street View, a new feature of Google Maps which provides 360° panoramic street-level views of various U. Google Street View is a feature of Google Maps and Google Earth that provides 360° Panoramic street-level views and allows users to view parts of selected Events 1085 - Alfonso VI of Castile takes Toledo Spain back from the Moors. Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. S. cities. On this date, the feature only included five cities, but has since expanded to twenty-three, with plans for more U. S. and Canadian cities in the future. Some cities, like San Francisco, are in high resolution, while other cities are limited in resolution.

Google Street View has also gained a significant amount of controversy in the days following its release; privacy concerns have erupted due to the uncensored nature of its panoramic photographs. [19][20]

Criticism

See also: Satellite images censored by Google Maps

Street map overlays, in some areas, may not match up precisely with the corresponding satellite images. Some locations on free publicly-viewable satellite map services including Google Maps, have missing incomplete or unclear map data. The street data may be entirely erroneous, or simply out of date:

The biggest challenge is the currency of data, the authenticity of data," said Google Earth representative Brian McLendon. In other words: The main complaints the Google guys get are "that's not my house" and "that's not my car. " Google Maps satellite images are not in real time; they are several years old. [23]

As a result, Google has recently added a feature to edit the locations of houses and businesses. [24]

Restrictions have been placed on Google Maps through the apparent censoring of locations deemed potential security threats. In some cases the area of redaction is for specific buildings, but in other cases, such as Washington, DC[25], the restriction is to use outdated imagery. These locations are fully listed on Satellite images censored by Google Maps. Some locations on free publicly-viewable satellite map services including Google Maps, have missing incomplete or unclear map data.

Canadian driving directions where the starting address is close to the US border have switched to imperial measurements, giving all directions in feet and miles, though the rest of Canada receives directions in standard metric.

Sometimes objects on Google Maps are hidden by normal clouds. For example, the mast of Arbrä Transmitter near Bollnäs in Sweden is hidden under a cloud [2].

A further weakness is that date and time when the photograph is made are not available. If it were, it would be possible to determine the height of a tall structure by measuring the length of its shadow.


Also, the map uses the Mercator projection, which is increasingly distorted towards the polar regions. The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator, in 1569
