Dear Experts,

                 This topic must have been discussed many times - but the threads are a bit confusing (for me!) to decide on the best possible course of action. I am writing here to be enlightened and hoping for some good advice.

I am looking out for the correct district boundaries for Kerala (India) as a shape or a KML file. We do a bit of citizen science activities in mapping birds in the state. However, the boundaries we have are off [=dated] for one of our districts (Ernakulam district), which I am trying to fix. 

After much looking up, I found a github repo which had 2011 data (which is post boundary changes for that district) but sadly, this particular change has not effectuated there. Infact, Google has the updated boundary ! There is also an SVG file with correct boundaries but I dont know how to convert it to a SHP or a KML file nor can I assess fidelity loss during a conversion.

Hence my next attempt was to look for Taluk/Panchayat level boundaries to fix this boundary myself but no shape file is available publicly at that administrative level.  Some JPGs elsewhere exists, which is very nice and detailed, to the village level or taluk level. I saw some discussion that the forum admin did attempt to procure the shape files of similar JPGs from the same source, but I do not see an evidence that she succeeded. Hence, I treat this as something that is not readily accessible.  

What I have/can? QGis & Inskscape, Scripting (python/perl/R) with limited GIS knowledge. 

Any help on how to proceed would be very much appreciated.

thanks & best rgds

PS: How I got the current boundaries is probably not much relevant - it reached me after several hand-overs and almost certainly its origins are from a publicly accessible website like GADM or 2011 Census Data.
