Google Maps   by jekky

satellite view provides high resolution satellite images for most urban areas in the united states including hawaii alaska puerto rico and the u s virgin islands canada and the united kingdom as well as parts of australia and many other countries the high resolution imagery has been used by to cover all of egypt s nile valley sahara desert and sinai also covers many cities in the english speaking areas however is not solely an english maps service since its service is intended to cover the world the highest resolution images are in some japanese cities such as tokyo citation needed various governments have complained about the potential for terrorists to use the satellite images in planning attacks 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 previously citation needed the united states capitol and the white house which formerly featured this erased housetop other well known government installations including area 51 in the nevada desert are visible not all areas on satellite images are covered in the same resolution less populated areas usually get less detail some areas may be obscured by patches of clouds 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 geological formations as of november 2008 update the u s national weather service also now uses within its local weather forecasts showing the 5 x 5 km point forecast squares used in forecast models although google uses the word satellite most of the high resolution imagery is aerial photography taken from airplanes rather than from satellites see

and sumatra only israel and parts of the west bank hawaii hong kong japan macau new zealand puerto rico russia moscow area only sabah sarawak taiwan south africa and the us virgin islands not all roads are featured in this country so directions are very limited has directions and places of interest implementation like many other google web applications uses javascript extensively 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 a hidden iframe with form submission is used because it preserves browser history the site also uses json for data transfer rather than xml for performance reasons these techniques both fall under the broad ajax umbrella extensibility and customization as is coded almost entirely in javascript and xml some end users have reverse engineered the tool and produced client side scripts and server side hooks which allowed a user or website to introduce expanded or customized features into the interface 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 interface the script insertion tool greasemonkey provides a large number of client side scripts to customize data combinations with photo sharing websites such as flickr are used to create memory maps using copies of the keyhole satellite photos users have taken advantage of image annotation features to provide personal histories and information regarding particular points of the area api google created the api to allow developers to integrate into their websites with their own data points it is a free service and currently does not contain ads but google states in their terms of use that they reserve the right to display ads in the future by using the api it is possible to embed the full site into an external website developers are required to request an api key which is bound to the website and directory entered when creating the key the api key is no longer required for api version 3 creating a customized map interface requires adding the google javascript code to a page and then using javascript functions to add points to the map when the api first launched it lacked the ability to geocode addresses requiring users to manually add points in latitude longitude format this feature has since been added for premier at the same time as the release of the api yahoo released its own maps api the releases coincided with the o reilly web 2 0 conference yahoo maps which lacks international support included a geocoder in the first release as of october 2006 update the implementation of google gadgets is simpler requiring only one line of script but it is not as customizable as the full api in 2006 yahoo began a campaign to upgrade its maps to compete better with google and other online map companies several of the maps used in a survey were similar to actively promotes the commercial use of its api some of its first large scale adopters were real estate mash up sites google performed a case study about nestoria a property search engine in the uk and spain for Mobile in 2006 google introduced a java application called for mobile intended to run on any java based Phone or mobile device many of the web based site s features are provided in the application on november 28 2007 for mobile 2 0 was released it introduced a gps like location service that does not require a gps receiver the my location feature works by utilizing the gps location of the mobile device if it is available this information is supplemented by the software determining the nearest wireless networks and cell sites the software then looks up the location of the cell site using a database of known wireless networks and cell sites the cell site location method is used by triangulating the different signal strengths from different cell transmiters and then using their location property retrieved from the online cell site database to aid my location in determining the user s current location wireless network location method is calculated by discovering the nearby wifi hotspots and using their location property retrieved from the online wifi database in the same way as the cell site database to further discover the user s location the order in which these take precedence is gps based services wlan based wifi based services cell transmitter based services the software plots the streets in blue that are available with a yellow icon and a green circle around the estimated range of the cell site based on the transmitter s rated power among other variables the estimate is refined using the strength of the Cell Phone signal to estimate how close to the cell site the mobile device is as of december 15 2008 2008 12 15 update this service is available for the following platforms android iphone os iphone ipod touch windows mobile nokia symbian s60 3rd edition only symbian os uiq v3 blackberry phones with java platform midp 2 0 and up for example the sony ericsson k800i palm os centro and newer palm webos palm pre and palm pixi on november 4 2009 navigation was released in conjunction with google android os 2 0 eclair on the motorola droid adding voice commands traffic reports and street view support the initial release is limited to the united states android 2 0 Cell Phones are being increasingly used for navigation assistance however written driving instructions are sometimes very confusing to follow while navigation devices have become a billion dollar industry navigation for android 2 0 is free an iphone implementation is also being planned features provided in the application search in plain english search by voice traffic view search along route satellite view street view car dock mode the neutrality of this section is disputed please see the discussion on the talk page please do not remove this message until the dispute is resolved january 2010 impact navigation is free and this will have a major impact on the navigation industry the drawback of for android is that an internet connection is required to get maps and related information from just like with iphone application it may be possible for google to circumvent the internet requirement a similar system is being developed for The Iphone shares of tom tom garmin and other navigation service providers fell by almost twenty five percent 25 after google s announcement of for navigation the application is only available initially to verizon users with android 2 0 or higher it is doubtful that users will continue to pay for navigation service if google provides it for free navigation is interrupted in cell phone dead zones in contrast iphone app operates as a traditional gps device when there no cell phone signal this is particularly relevant on streets with high rise buildings and on highways parameters in url parameters may be tweaked to offer views and options not normally available through on screen controls 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 a list of parameters and their descriptions is available development history first started as a software application developed by lars and jens rasmussen for the company where2 in october 2004 the company was acquired by google inc where it transformed into the web application the application was first announced on the google
