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.

The Bicycling Layer...

    Recreational cyclists and bike commuters alike can plot cycle-friendly routes, find trails, and avoid snarling traffic with Google Map's Bicycle layer. Map's bike-friendly, green-toned map layer is very eye-pleasing. The Google Maps API allows you to add bicycle information to your maps using the BicyclingLayer object.     The BicyclingLayer renders a layer of bike paths, suggested bike routes and other overlays specific to bicycling usage on top of the given map. Additionally, the layer alters the style of the base map itself to emphasize streets supporting bicycle routes and de-emphasize streets inappropriate for bicycles.     Let us have a look at the following example. The code has a map which is centered at Pune, India. There are very few cycle tracks in Pune and so you will see just a few dark green lines on the map. But if you would change the latitude-longitude values in the code and center the map at USA, then you will see a...

Google Map's Real-Time Traffic Layer...

    You can now check the traffic condition on the road before you leave for work, or a party or to your friend's place. Google's Traffic layer shows the traffic conditions in your area - LIVE!!! Live traffic data is available in major cities in the United States, France, Britain, Canada and Australia, with new cities and countries frequently added. The Google Maps API allows you to add real-time traffic information (where supported) to your maps using the TrafficLayer object. Traffic information is provided for the time at which the request is made. Consult this spreadsheet to determine traffic coverage support.     Let us now have a look at the Google Maps API - Trafiic Layer example. Copy the following code in a simple text file and save it as html. Click on this html file and it will open in your default browser. You will then see the traffic conditions in your area - LIVE...     The output of the above code looks as seen in the r...

On-click polyline

    Following up on the last example where we saw how to add a hard-coded polyline to our map, today we will see a more user interactive polyline example. In this example we will discuss on-click polyline! What you need to do is, copy the following code into a txt file and save it with dot html (.html) extension and then view it in your browser. So here goes the code!     The output of the above code will be a map centred at Mysore. Click on the map for the first time and a marker will appear there. On the next click, another marker will appear with a polyline between the 2 markers. This will continue for all further clicks and here you have your "On-click polyline" running! The map looks something like seen in the image below!     The next step to this code will be creating a polygon. We will see examples to create polygons on the map at a later stage! If you have any queries or suggestion, please drop a comment here or feel free to ...

Where does Google have live traffic information?

Where does Google have live traffic information.md Where all can I see the real-time traffic data? This question has been asked a several hundred times by several hundred people on several hundred forums. Probably you too have had this question. Well, we now have an answer to it and a very good one. Click on the image below and you would be redirected to a map from Google which will show you all the places at which live traffic data is available. Hope you’ll enjoy this and quench your thirst to know more about the Google Real Time traffic data. Update 10/31/2017 Previously the availability of traffic would be shown as seen in the image below, but now you need to be at a minimum of zoom level 5 and centered on the location of your choice to see where traffic data would be avialble. If haven’t already read from where Google gets it’s traffic data, be sure to check out this earlier post. Do post any question you have about the Google Maps, and I will try and answer as many as I can. Fo...

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...
