GIS Technology to identify all properties in BBMP Limits

          The Bruhat Bangalore Mahanagara Palike (BBMP) has for the last two years, been in the process of conducting a massive exercise to map the 13.87 lakh properties in the 198 wards in the city. Geographical Information System (GIS) has proven to be an effective tool for analysing and displaying thematic maps of all the roads for proper evaluation and correction of zones.

           As of now, 11 lakh properties have come under the tax net. The aim of this programme, which is perhaps the first such exercise being conducted in the country on such a large scale, covering 800 square km, is to bring all properties under the tax net and ensure that the BBMP has accurate information pertaining to the properties’ dimension, built-up area, land use and classification. The process of validation of GIS maps will be completed in January 2011.

          The process uses satellite digital maps of the BBMP area to generate a vector map from the information obtained. These high resolution satellite images are then used to extract details of roads, plots and buildings. However, the challenge will be to tag properties in zones that do not have an orderly maintenance of records, and to demarcate tank bunds, government lands and slums. The old BMP area constituted 225 sq km of area and with all the wards and numbers having been changed to include them in the 800 sq km new BBMP area, the ward boundaries have also changed and these changes will have to be incorporated.

          The new property identification numbers (PIDs) will be a complete identity of your property - not just updation of ward numbers. They will be ‘geo-tagged’ with the exact spacial dimensions of your property and have the latest photograph of your house. After January, one can access details on the BBMP website about any property in the city using the PIDs. There are two teams assigned per ward. Each team comprises engineers, a tax inspector and revenue inspector. These teams have been going around the ward, mapping properties and taking their photographs. They will be equipped with self-assessment scheme (SAS) property tax data collection and verification sheet. Special notice will be issued instantly to those who have not paid tax. For this to happen, the BBMP officials will be working together with KEONICS for immediate updation in the database.

          With GIS-based property survey finally reaching completion, it will now have access to a complete property database with details of dimensions, directions and land use. Even the number of floors in each building can be tracked. It’s a tough target ahead for the BBMP, with just a little over three months remaining, to meet its Rs 1,500 crore estimate from property tax for this financial year. As on December 9, 2010, BBMP has collected a total of Rs 904 crores from 10.12 lakh properties across the city. This is its highest collection with the revised tax under the self-assessment scheme (SAS) The cost for the base map preparation is around Rs 2 crores.

  4. Hello Mr. Shreerang,

    Can you help me to get revised BBMP map with area of 800 sq.km. When i downloaded the BBMP map from BBMP.org site and digitised, i am getting the area around 728.99 sq.km. Why this discrepency!?

    Regards,

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...

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 .

Form info window

         Today we will look at a Google Maps API v3 example to add a form in the information bubble! This is usually required when we wish to accept some data/information from the user! This data can be saved to a server in the form of an XML file or a database! The information can then be retrieved back at a later stage, when necessary!          In this example we will only look at form in the information bubble! The connectivity part with the server will be discussed in another post! So, today's code snippet is as seen below! <html> <head> <title> Google Maps API v3 - Adding marker and info window on Click and creating a form in the infowindow with the lat-lng information in it. </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using ev...

Retriving co-ordinates...

         We have seen 2 Google Maps API v3 examples wherein we have retrieved the latitude-longitude co-ordinates of the point of click on the map. In the first example we have displayed the co-ordinates in the information window and in the second , we have displayed the co-ordinates in a form in the information window.         Today we will create a code to retrieve the latitude longitude co-ordinates in a text box while simultaneously a marker appears on the map as well. So, here goes the code. <html> <head> <title> Google Maps API v3 - Adding marker on Click and retrieving the co-ordinates in a text box </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using event as a parameter to a function declare map, strictly as a global variable fun...

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...
