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.

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...

Jquery Mobile - Basic Listview

    Continuing with the Jquery Mobile Examples, today we will take a look at the listviews in Jquery Mobile. Listviews are popularly used in websites and web-applications that are built on the Jquery Mobile platform and hence we will look at the various list patterns available with Jquery Mobile. Lists are used for a various purposes like data display, navigation, result lists and data entry. We will start with the most basic listview example and look through several examples over a number of posts.     A listview is simply an unordered list containing linked list items with a data-role="listview" attribute. jQuery Mobile will apply all the necessary styles to transform the list into a mobile-friendly listview with right arrow indicator that fills the full width of the browser window. When you tap on the list item, the framework will trigger a click on the first link inside the list item, issue an Ajax request for the URL in the link, create the new pag...

The bitter divorce of PSD and HTML

    Today's article is an interesting post that I read. The original post in Portuguese and authored by Fabricio Teixeira  can be found at arquiteturadeinformacao  (Now don't ask me pronounce this =)).     Some are calling it the death of PSD  but I prefer calling it a "divorce". PSD and HTML are both healthy and living strong, just that they do not live together anymore. "PSD to HTML", which for years was the most accurate and sometimes the only right path to web design process, seems like has its days counted.     Firstly you draw a page in Photoshop; impeccable layout, representing exactly how the web pages would appear when opened in a browser. After a sign-off on this picture (PSD) from the client the front end developer transforms these pictures into HTML, CSS and Javascript. The assets are cut, one by one, exported from the PSD and integrated into the HTML. Plugins and new tools are created in the process and some companies eve...

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...
