Four maps on the same page - Playing with events

    In today's example we will see how to add 4 maps on the same web page and then play a bit around with some events in Google Maps API. Lets have a look at the code. All that you have to do to get the code working is copy the code in a text file and save it with .html extension. Open this html file in your browser and you will see the four maps in action!




    Adding the four maps on a webpage should not be a challenge anymore, and all the more after the example Two Google Maps - Side by side that I shared a few weeks back! All you need to pay attention is to the events. There are two events "drag" and "zoom_changed". As the event names suggest, when you will drag or zoom the first map (upper left map), the remaining three maps will also zoom and pan accordingly! Try it out and leave a comment of what you think of it! You can also drop your queries or doubts about the same here!

    The output of the above code appears as seen in the results section above! Hope you enjoy this example!

    Hi there, This is very cool. Many thanks. I'd like to ask if it's possible to have 4 different maps (different LatLng for each map) on one page. Thanks for your time. Paris

      Hi Paris.

      Of course you can do it. Just set the center attribute to different values in the code.

      Give it a try and let me know if you were able to do it. If not I will tell you how it is done.

      Regards,

    How do I set the center attributes different for each map?

      That's easy. You will need 4 different variables like latlng1, latlng2, etc. Each variable will hold the lat-lng value of the centre of the map.

      Now you change the myOptions variables accordingly and you will get 4 maps centred at 4 different locations.

Playing with the markers and info window bubbles...

    In the last few posts, we have seen some marker examples and some information window examples. Now, lets do something interesting combining these two things. Just writing that "This is an info window" in the information bubble is not very interesting! And I know this...Have gone through the same phase!     So, today we will do something interesting! We will display the latitude- longitude co-ordinates of the point that the user clicks on the map! Doing this is not at all complex! Copy paste the following code and you will see for yourself a map coming to life!     The output of the above code looks as seen in the result section above! If you have any queries regarding the above code please comment on the blog post or feel free to contact me at my mail ID .

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...

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...

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...

A Giant called Google...

    Wondering what you will be reading in this post today and what is "Google Giant"! Well, I was working on a simple project a couple of months back and that is the time when I was amazed and by the size of data that Google Maps servers might be having! As most of the readers (developers and enthusiast included) would know or might have noticed, Google maps are rendered by stitching small images together. You must have observed this on quite a number of occasions, when you see grey tiles when you have a slow internet connection in particular. It takes time for the images or tiles as we call them to be displayed.     Let us try and estimate what could be the size of the Google Maps data! Before proceeding, let's make a few assumptions and considerations. 1. Let's consider the Google Street View maps only. 2. The zoom level that is considered for the calculations is 21 - the max zoom level allowed on Google Maps API. 3. All the numbers are just an esti...
