Hi Bharath,
It will be better tracked and resolved there. On this mailing list your post will get buried in a few days time, and there are several request posts just like yours (
search here) so it'll be lost in a crowd and may not get noticed later on.
On github, it will stay visible in long term. Others who have that data in some other form like PDF will share it. Someone else will come, take up the geotracing task and share the shapefile (like I did for Pune). So in case you don't get immediate response here, you'll have higher chances of success there.
Note: if you do create a ticket/issue, please make a separate one for each city. That way they can be tracked individually
