140 users have liked.

 The latest version of Google earth has introduced a new feature of viewing the earth at different periods of time, starting with the year 2000. This allows us to see the changes on any part of the earth over a given period of time starting with the year 2000. I had listed in my earlier blog entry about 48 lakes as on May 15, 2009. Here I give a list of of 43 lakes, with two links, a and b. The link (a) pertains to an earlier time where as the link (b) is for current (May 2009) period.

Kindly browse and give your comments if any. Casual scrutiny is not revealing, though. There are no maps seperately for the earlier Google earth data. This makes it difficult to visualise any change in land use authentically.

An onsite study is perhaps in order.

  Sir,

     Indeed you are working on an important topic. But, I guess, the two links provided here are the same data ( ie. the same date and location). I can believe if the surrondinngs of the lake have witnessed no change over the decade. But, can the shape of the froth over the lake be exactly the same?

Yes I agree

 The two seemed to be identical. Yes the froth was also identical. I have now replaced the earlier links with those giving the Google Earth pictures at different years directly. we can see the difference with this correction. Thanks Mr. srivastava V.

My God, such excellent work, and so hidden and buried on Praja. Well nothing new, but I will take your lake out pics of some lakes that have seen big changes in this period 2000-2009 and highlight the point you have made here.

It is now almost 4 years since sept 2009 comment by SB. Lot of water has flown since then.

Planning to down load the most recent version of Google earth, to contunue the work further.  A huge area of the lake bed is being claimed for commertial purpose since then. Click [1]

Bellandur Lake is approachable from behind this Temple near Sarjapur road fly over

As seen behind the Temple wall. It was a feat to take this picture beyond this 5 feet [?] heigh wall though!

I could have gone near to the water, but was difficult to walk on the difficult terrain without a proper foot wear.

A meeting with the head of google operations in asia pacefic,at Bangalore may be useful. This can be thought of as and when required.

Great contact sir. But why bother him right now. Unless its tough to pull out old satellite pics ourselves.

Meanwhile, pulling out pics from your earlier work.

Here is May 2002

 
And in April, 2008
