 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.

Something not correct!!

Srivatsava - 17 May, 2009 - 01:21

  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?

 

-Srivatsava V

Yes I agree

psaram42 - 18 May, 2009 - 03:19

 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.

Excellent work sir

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.

Not needed sir. here, 2 pics of Bellandur Lake, 2002 and 2008

silkboard - 7 June, 2013 - 10:22

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

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.
