The mobile meta tag

If you have ventured into the world of Mobile web development, you would have realized the importance of the viewport meta tag in the head section of your HTML page. Without the proper meta tag included in your HTML, your web page would zoom, move, be dragged around and basically not client acceptable. To avoid all of this, we need to include a viewport meta tag in the HTML in the head section.

Jquery mobile suggests the users to use the following viewport meta tag.

By using the above viewport meta tag, the width would be set to pixel width of the device. This would avoid the resizing of the page and there-by the web page would not be draggable any more. However, this would not disable our zooming issue. The user can still zoom the web page by tapping the screen or by pinching it. Jquery mobile suggests that this is a feature that should be included, however, many a times, in most cases, this is not desirable. By using the above meta tag, your web page won't zoom when the device is in the Portrait mode, but when you change the orientation of the device the user can start zooming the web page. To avoid all of the above issues, the following meta tag should be used instead of the one suggested by Jquery Mobile.

The user-scalable=no property disables the zoom feature of all the mobile devices in both the orientations. Hope this post helps a lot of web developers who are or would have faced this issue.

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...

Two maps on the same page - Side-by-side

How good I am feeling to post a code example after such a long time! It's been all "news" over the past so many posts! Well now that I am finally doing a code example, I am posting a very highly requested code sample. Placing two Google Maps on the same page (Now that's simple you would say!), but side by side. Now this is the thing that most people struggle with. Well, implementing the second part is also very simple, as you will see in today's code. Let's see the code. Here it is! The output of the above code will be as seen in the result section above. As most of you will realize, there are two maps, one centered at "Pune" and other at "Noida". Why I chose these two locations? Well, just like that!...The main issue of concern is how the maps appeared side-by-side and not one below the other as would be normal behavior of two "div" elements used in the same page. Now here is the trick! Check out the...

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 .

How I authored a technical book?

Here is the reason why I have not been writing over the last 6-8 months! I was busy writing my first technical book - Mastering jQuery Mobile with +Chip Lambert and what better subject to choose than jQuery Mobile. I have been extremely lucky to get the opportunity to author a book with Chip. This project started off about a year back, when I was approached by Packt Publishing to review this book that was being written by Chip. I instantly grabbed this opportunity, as I was getting a chance to review some work on a framework that I totally love. Chip had about 4 chapters complete at this time and I had provided my comments on the content of these chapters to the best of my knowledge. I was waiting for the further chapters, when I fine morning, I received a mail from the content editor of the book... I thought that it would be the next chapter for review. But nope! It was him asking me if I would like to author this book with Chip, to speed up the process as C...

Integrated GPS cameras...

GeoSpatial Experts has introduced three new GPS Camera bundles designed specifically for geotagging and mapping digital photographs. The firm now offers its popular GPS-Photo Link 5.0 photo-mapping software with the new Ricoh G700SE, Sony A55, and Casio EX-H20G GPS cameras. All of the GPS cameras below will provide you with geotagged photos, additionally, some can also offer the ability to capture the direction the photo was taken with a built-in compass, or the ability to collect attribute data in the field. WiFi and Bluetooth will allow you to communicate with laser range finder equipment to measure exact distance from the photographer to the item being photographed. Some GPS cameras provide a ruggedized camera to withstand harsh conditions. In 2007, Ricoh introduced its 500SE model as the first GPS-eq...
