Comments

  1. These are undoubtedly the best examples I have come across. Simple and easy to understand. I have found them most helpful. I would be eternally grateful if you could post an example that finds the user's current location and then calculates the route with directions to a fixed location. Thank you and keep up the great work!

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 .

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...

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...

Geodesic Polyline

    Today we will have a look at a very interesting polyline example - "The geodesic polyline". Now the first question that will pop is "What is geodesic?". Mathematically, geodesic means the shortest line between two points on a mathematically defined surface, as a straight line on a plain or an arc of a great circle or sphere.     The next question after reading the above definition is clearly, "Why do we need geodesic polylines?" and that would be followed up with "What is this Great Circle?". We will discuss this first, before we move on to the actual example today. The example is very very similar to the normal polyline example, with just a small change.     Having said so, I will now try to explain why we need a geodesic polyline? The shortest distance between two locations on the earth is rarely a straight line as the earth is roughly spherical in nature. So any two points on the earth, even if they are very close lie on a curve a...

Jugnu: India's first Nano Satellite

          IIT-Kanpur with its nano satellite 'Jugnu' has set new highs in the field of space research. A team of students, working under Dr NS Vyas (the visionary man behind the making of the nano-satellite) and other faculty members of the institute, have successfully made the country's first nano-satellite to be developed for the first time by any educational institute.           The development of the Jugnu started in the year 2008 with a team of 3 students. With time, the team has grown to the size of more than 50 students ranging from 1st year undergraduates to final year postgraduates and 14 professors from different disciplines to complete this challenging mission.            The satellite has been handed over to two ISRO scientists, DVA Raghav Murthy (Project Director, Small Satellite Projects) and Dr SK Shiv Kumar (Director, ISRO sat...
