No, iPhone location tracking isn't harmless and here's why
Analysis It didn't take long for the blogosphere to pooh pooh research presented on Wednesday that detailed a file in Apple iPhones and iPads unknown to the vast majority of its users that stored a long list of their time-stamped locations , sometimes with alarming detail.On Thursday, a forensics expert who sells software to law enforcement agencies gave a first-hand account why scrutiny of the location-tracking database is crucial. We'll get to that in a moment. But first, let's take a sampling of the rampant naysaying.
The most common criticism was that the contents of the SQLite file, which is stored on the phone and on any computer backups, were wildly imprecise. Blogger and web developer Will Clarke , for instance, used the researchers' freely available software to map the coordinates gathered by his own iPhone during a recent round-trip bike tour he took from Philadelphia to New Jersey. When he compared the results to the actual route, he found that “almost all the points were way off.”
In an interview with The Reg , he said some of the points on the resulting map were as much as 3,000 meters, or almost two miles, away from his true location.
“The data that is exposed basically reveals which city you were in at a given time,” he concluded in a post that called the research “sensational.” “Nothing more specific than that. It can't tell what house you live in, it can't tell what route you jog on, nothing like that.”
He went on to conclude: “Apple is not storing the device's location, it's storing the location of the towers that the device is communicating with.”
Software analyst David “Lefty” Schlesinger found similar inaccuracies when he used the database contents of his iPhone to plot a train ride he took in July from Amsterdam to Den Haag, about 60 kilometers away. He also found that the iPhone file showed he was in Santa Cruz, California, on Christmas Day and traveled as much as 80 miles, when in fact he stayed in the state's Central Valley, some 130 miles away, the entire day.
Like several other bloggers, he also noted huge inconsistencies in the time intervals that locations were logged. Sometimes iPhones and iPads went days without updating the database, and on one occasion went almost two weeks.
The critics make a valid point that the data stored in the consolidated.
Map Location By Lat And Long - News

The first in the browser, an application which uses javascript to report location (lat/long) and fetches a series of venues, shops, clubs etc, within a 0.5 radius (more on this application later). The second, an actual mobile native app on the device.
WP7 only transmits location data when an app requests it. Compare that to Google collecting it as long as location services are on or your beloved Apple who collects that information in the background no matter what settings you turn off.
Geographical location to latitude and longitude using Yahoo Maps ...
Converting address to latitude and longitude is necessary in many applications. Various websites are providing APIs to consume this service. Yahoo is one of the top sites with user limit of 5000. User limit is figure kept by corresponding sites which indicates maximum number of requests it accepts per day from a particular IP. Google’s limit is 2500.

We need only one php file for this demo. Â The file contains a php block which gets serialized php data from yahoo api. Below written is the code
<?php error_reporting(0); if (isset($_GET["address"])) { // output=php means that the request will return serialized PHP $request = 'http://local.yahooapis.com/MapsService/V1/geocode?appid=ofRNGV6m&location="' . urldecode($_GET["address"]) . '"&output=php'; // receiving the response of request $response = file_get_contents($request); //converting response to a multidimensional array $phpobj = unserialize($response); } ?>
Now, there is another javascript block which marks the address on google map. Here is the code.
<script type="text/javascript"> function initialize() { var tlat=document.getElementById('latitude'); var tlon=document.getElementById('longitude'); var latlng = new google.maps.LatLng(tlat.value, tlon.value); var myOptions = { zoom: 4, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); var markerdraw = new google.maps.Map Location By Lat And Long - Bookshelf
