Blue census, Water census...

The Uttar Pradesh State Water and Sanitation Mission (SWSM) will soon be documenting the drinking water resources across six zones of the state. These zones are Allahabad, Ghaziabad, Gorakhpur, Lucknow, Varanasi and Moradabad. The documentation - to be done through Geographical Information System (GIS) and Global Positioning System (GPS) mapping - will take note of ponds (manmade and natural), wells and handpumps. This exercise which is a part of the National Rural Drinking Water Programme (NRDWP) will help the officials to create a proper database of these resources, which will be used for their management.

Through the mapping, all the details of all the resources will be compiled, complete with their longitude and latitude dimensions. The department plans to start off the exercise by April 1, 2011 and should end by March 31, 2012. The focus will initially be on villages where the drinking water condition is really bad in summer and this data will be mapped within three months. This would help the authorities to finalise plans for providing emergency relief to these villages. After the mapping, the details will be given to the selected civil society organisations in these villages, who will then do a regular monitoring of the water quality.

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 …
