The mystery of the "Vanishing Island"

    A 60 square mile land mass know as the Sandy island or the Sable Island has vanished without a trace from the Pacific Ocean. This island was supposed to be located between Australia and New Caledonia and can be seen in the older versions of Google Maps and several other scientific and nautical maps.

The original location of the Sandy Island

    Just recently a research vessel sailed to the location to find nothing but deep blue Pacific more than 4,500 feet deep. The researchers and doctoral students overboard the ship saw this mysterious island on all the scientific maps and weather maps but not on one navigational chart that was on their ship. There was no indication of any land mass at the exact location where the Sandy Island was shown.

    If Sandy Island did exist, it would sit in the French territorial waters. But the French government denies that any of its official maps ever listed the invisible island. If such an island never existed, how did it find its way on several maps. Google is not the only one to depict this invisible island. Bing Maps, Yahoo maps and several other nautical maps, weather maps and scientific maps show this phantom island at the exactly same location.

    A number of theories abound about the mysterious island. For instance, it's possible that it was added to a map at some point to prevent copyright infringements. This sort of tactic is common on street maps, where phantom streets are sometimes added to flag counterfeiters. But the practice is highly unusual for nautical charts, since these maps rely on strict accuracy for their credibility. Google Maps does not show this mysterious Sandy or the Sable Island.

 The current Google Maps does not show Sandy Island

    The phantom island, which is also called Sable Island on some charts, is reminiscent of another famous fictional island, the one from the television series "Lost". In the series, a group of strangers crash land on a mysterious island in the middle of the Pacific Ocean. The island is eventually revealed to possess magical qualities, such as the ability to become invisible when outsiders search for it.

    Could this disappearing island be a case of fiction masking reality? It's certainly fun to think about.

Difference between word-break: break-all versus word-wrap: break-word

The 2 CSS properties word-break: break-all and word-wrap: break-word appear to work in the same way or generate the same output, but there is a slight difference between the 2 and we will be discussing these differences today.



    Take a look at the example above. The difference is quite evident, however I will try to explain it further.

word-break: break-all Irrespective of whether it’s a continuous word or many words, break-all breaks them up at the edge of the width limit even within the characters of the same word
word-wrap: break-word This will wrap long words onto the next line.break-word adjusts different words so that they do not break in the middle.
    So if you have many fixed-size spans which get content dynamically, you might just prefer using word-wrap: break-word, as that way only the continuous words are broken in between, and in case it’s a sentence comprising many words, the spaces are adjusted to get intact words (no break within a word).     In case you want to exp…

Geodesic, Draggable Onclick Polygon

After creating a simple polygon and then creating an on-click polygon, we will today see how to create a polygon which can be changed, altered, dragged; basically edited on the fly. We will also cover the geodesic polygon in this example itself. If you want to read and understand more about what "geodesic" is, read this post.

    Nothing exceptional about the code that I think needs explanation! You can create a geodesic polygon which can be edited on the fly. Click, hold and drag any marker, and the two polylines connected by this marker will change accordingly. By clicking on the marker, that marker would disappear, and the polygon will reform itself! Here is today's code.


    You can copy the above code in a text file and save it with .html extension. Click on this file; it will open in your default browser and you will see an exciting map in action! The output of the above code appears as seen in the result section above! If you have any doubts or queries regard…

Onclick polygon

Yesterday we had a look at a simple polygon example. But that example was not exciting as it was all hard-coded with no user interaction and which means no fun! Today's example will deal with creating a polygon on the fly, i.e. an on-click polygon in action!

    The code for creating a polygon is very much similar to creating a polyline! The only difference is that you need to replace "Polyline" by "Polygon" in such examples. Let's head on to our code.


    The output of the above code can be viewed in the result section above. If you have any doubts or queries regarding the above code then please comment here or feel free to drop me a mail! Till then, happy mapping!

Jquery Mobile - Readonly listview

The Jquery Mobile Listview that is used generally used to link each list item to a new page in the application or to link that list item to another list. However, it is not always necessary to have a linked list. Sometime we need to display a list that does not have to be linked to anything else.

    Using Jquery Mobile, we can have non-interactive, read-only listviews in our web pages. This list can be generated using the ordered or un-ordered lists that don't have any linked items, i.e. we basically do not include any anchor tags within our list item tags. This will render the listview as a non-interactive, read-only listview.

    Take a look at the JsFiddle below. The code and the actual result will give you a better picture of how you can implement the non-interactive, read-only listviews.



    Hope you find this example useful. Please drop a comment if you face any problems or have any queries. I would be happy to help and learn more. You can take a look at more examples …
