Multiple markers...

            It rarely happens that there is just one point of interest or just one location that you would like to mark! Generally there is a bunch of markers that appear on the map! Specifically, you want a list of latitude and longitude pairs representing the points of the markers you'll plot.

            To store the list of points, you can combine the power of Javascript's array and object constructs. An array stores a list of numbered entities. To access the elements of the array, you must use their numeric indices. So array[0] will point to the first element in the array while array[n] will point to the nth element in the array.

            I will use the following piece of Javascript code to demonstrate how multiple markers can be made to appear on a map using the array structure and the for loop for iteration.



            Nothing here should be much of a surprise! You can see that the google.maps.Marker function is called for each of the markers, so you can see two markers at two different locations on the map. The result above displays the output that is generated. Feel free to add your own locations and more number of markers on the map! Keep following for more examples and more information on GIS! Till next post, happy mapping!

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...

The bitter divorce of PSD and HTML

    Today's article is an interesting post that I read. The original post in Portuguese and authored by Fabricio Teixeira  can be found at arquiteturadeinformacao  (Now don't ask me pronounce this =)).     Some are calling it the death of PSD  but I prefer calling it a "divorce". PSD and HTML are both healthy and living strong, just that they do not live together anymore. "PSD to HTML", which for years was the most accurate and sometimes the only right path to web design process, seems like has its days counted.     Firstly you draw a page in Photoshop; impeccable layout, representing exactly how the web pages would appear when opened in a browser. After a sign-off on this picture (PSD) from the client the front end developer transforms these pictures into HTML, CSS and Javascript. The assets are cut, one by one, exported from the PSD and integrated into the HTML. Plugins and new tools are created in the process and some companies eve...

My first blog!

          " W hy is it that there are no Goolge Maps API examples which show India specific data?"...This question kept bothering me all through my learning phase. I always thought why aren't there any examples that use a map which shows Indian locations. Anybody who is new to Google Maps API application development would love to see a location that he knows of on the map! This is what I longed for all the way through and now have decided to put up simple examples and other supporting data for building customised simple Google Maps and all will show locations in India! When starting something new, if one finds something familiar out there, then it gives a feeling of comfort! And this is what I will try to provide to all those out there who are facing a similar problem that I faced! I am not an expert at Google Maps API, I am learning too...But, I will like to help out people along the way! So, all comments from the novice to the profession...

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 .
