Quake Risk Assessment Application...

            A GIS application has been designed to help the Chennai Corporation and the departments concerned to take quick decisions when a major earthquake strikes the city. The application has been prepared based on data collected as part of the seismic vulnerability screening of over 50,000 buildings with more than three floors by the civic body in association with the Centre for Disaster Mitigation and Management, Anna University. However, buildings in the defence areas were not covered in the seismic vulnerability screening.

           The civic body has started taking measures towards providing the GIS application to other agencies such as Fire and Rescue Services, Police and Home Guards. The GIS application could be used to find out if any of the residential or commercial buildings with three of more storeys are safe when an earthquake strikes. The number of buildings that are likely to be damaged with a particular magnitude of earthquake in the city could be estimated.

           As soon as an earthquake with a certain magnitude is recorded in the city, the officials of the civic body would be able to trace the buildings that could have got damaged using the GIS application. The safe escape route of the injured residents of the damaged building to the nearest hospital would also be mapped with the help of the GIS application and the authorities at the ward level would take action at the quickest possible time. The application would also be used to make a decision on the establishment of relief centres by locating strong earthquake-resistant structures in each of the 155 wards of the Corporation.

           The civic body is likely to take a decision shortly on permitting the public too to make use of the GIS application for better disaster preparedness. This could help those purchasing an apartment in a multi-storeyed residential building make an informed decision.
 
            More and more such applications of Risk Assessment using GIS should be implement throughout the states in India, as India faces the risks from natural catastrophes like floods, earthquakes and tsunamis. These applications will definitely help the government and also the people of the country in making wise decisions while buying property, land, etc.

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…

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!

Get directions between different states in India

Having seen a simple hard coded directions example yesterday, today we will have a look at another simple example but not an hard coded one. In today's  example we will see the directions between different states in India. We have two simple list boxes stating Origin and Destination as lists of the states in India. You can select a state from either of the lists and then you will get the directions between the two selected cities.

    If you see yesterday's code and today's code you will find a lot of similarities and so  it would be easy to follow. The code will look lengthy, but it is just because of the list boxes code. So don't worry about the code, just go for it.


    The output of the above code will look as seen in the results section above. Hope you find this code helpful in understanding the directions services even further. Tomorrow, we will look at another - a bit complex example. Till then, happy mapping.
Note: The above code will not display any results …

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 the first
