Is Google cheating?

I found this piece of interesting fact, accidently while browsing the internet. Google shows different maps for India, China and USA. Confused hun! Well don’t be…Just read on… In Indian version of Google Maps, you can see Arunachal Pradesh and eastern part of Jammu and Kashmir as integral part of India. In US version of Google Maps, you can see Arunachal Pradesh and Jammu and Kashmir as a disputed region. In the Chinese version of the Google Maps, you can see Arunachal Pradesh and JnK as not a part of India. Many people complained this issue to Google. A Google employee responded : “ We do show different versions of this border, because we required to by law. Indian law requires us to show it one way, and the Chinese law requires us to show it another way . If we can legally do so, we strive to present b...

Form info window

Today we will look at a Google Maps API v3 example to add a form in the information bubble! This is usually required when we wish to accept some data/information from the user! This data can be saved to a server in the form of an XML file or a database! The information can then be retrieved back at a later stage, when necessary! In this example we will only look at form in the information bubble! The connectivity part with the server will be discussed in another post! So, today's code snippet is as seen below! <html> <head> <title> Google Maps API v3 - Adding marker and info window on Click and creating a form in the infowindow with the lat-lng information in it. </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map; //When using ev...

Retriving co-ordinates...

We have seen 2 Google Maps API v3 examples wherein we have retrieved the latitude-longitude co-ordinates of the point of click on the map. In the first example we have displayed the co-ordinates in the information window and in the second , we have displayed the co-ordinates in a form in the information window. Today we will create a code to retrieve the latitude longitude co-ordinates in a text box while simultaneously a marker appears on the map as well. So, here goes the code. <html> <head> <title> Google Maps API v3 - Adding marker on Click and retrieving the co-ordinates in a text box </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map; //When using event as a parameter to a function declare map, strictly as a global variable fun...

Drive along - Cool coding

This is something that will demonstrate to you the power of mapping! This is a Google Maps API v2 example, but just copy and paste the code in an html file and you will see something very cool! This will prove that mapping is real fun! Let's have a look at the code first. Copy this code in your html file. Don't worry about the length of the code and the post in general. Just execute the code and you will surely enjoy what you see! <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title> Drive Along </title> <script src="http://maps.google.com/maps?file=api&v=2&sensor=false&key=ABQIAAAAu3HXU_hLdVPTFGqLed_FCxT2yXp_ZAY8_ufC3CFXhHIE1NvwkxQbblEPYBGNoRsuuSU9aBfSq4VAZA" type="text/javascript"> </script> <script src="http://econym.org.uk/gmap/epoly.js" type="text/javascript"> ...

Where does Google get it's live traffic data from?

Referring to a post that I wrote earlier, Google’s - Live traffic Layer , ever wondered how Google collected this data? I was wondering the other day, how Google received live data to display it on their maps as a layer! I looked up the web and found something very interesting and am sharing the same with you all. As we all know, the traffic layer is available most accurately in several states in USA. Most major metro areas in the US have sensors embedded in their highways. These sensors track real time traffic data. Easy to miss at high speeds (hopefully anyway, traffic permitting), more commonly noticed may be the similar sensors that often exist at many busy intersections that help the traffic lights most efficiently let the most amount of people through. The information from these tracking sensors is reported back to the Department of Transportation (DOT). The DOT uses this data to update some of the digital signs that report traffic conditions in many metro areas. They als...
