In Continuation of my previous email, here is a CSV file
which shows just how bad the GDAM dataset is.

Hi Sharad,
I just download the GDAM data again, to confirm what you
have said.
I'm going to have to disagree with you about the quality
of the IND_adm3 data.
Acoording to the 2001 Census, there are 5454 Sub
Districts in India
<http://www.socialjustice.nic.in/pdf/tab11.pdf>. The GDAM
dataset has just 2299 features.
So clearly these taluk features do not correspond to the
2001 Census. I cross checked for some areas I have ground
knowledge of, and I can say that this dataset is not from
any specific era. Some tehsils in the file were created
post 2001, while others created in the 90's were not present.
In my opinion the GDAM data is pretty much unusable.
Regards,
Devdatta

I have downloaded and checked the GADM boundaries (my
version is 2011). The taluka boundary layer probably
holds good today, becuase few talukas get split.
Districts get split regularly (every so many years)
so the district boundary layer in this GADM set is
quite of date (may apply to 2001 or so). The spatial
registration (positional accuracy is ~1km, and the
spatial detail is of course not as good as the
boundaries given in a Survey of India 50k topo, but
then that is an unfair standard, so by a more
generalized standard, the quality is okay.

Mr Thakkar,
Please also look at another post (more than one)
on this group about Taluk Shapefiles by Justin
Meyers
So far as I know GADM is the source that has
Taluk files.
I am not sure about its completeness and accuracy
as on today

Sharad,
I am working on some things will revert
in about a week or may be more.
Thejesh,
Go ahead,
Actually there was one more source a Low
Resolution (vertices) District map by VDS
technologies.
I have it as Polylines in Autocad. I seem
to have lost the original file.
If anyone has then please share it. (it
does not seem to be on their site now)

Dear Dilip and others:
I have been following this thread
with interest, but to be honest
am a bit lost now. Can someone
post a summary of which maps
mentioned so far have what
features (which coverage,
pertaining to which year, what
attributes (such as census
codes), etc.)? Would be most helpful.

Hello,
This is an old post.
However this is the
appropriate place to add an
additional source.
I had downloaded the set from
Grid Geneva many years ago.
The original complete source
was named as GNV197 which is
24 MB
Titled as "HUMAN POPULATION
AND ADMINISTRATIVE BOUNDARIES
DATABASE FOR ASIA"
I am attaching the South
Central Asia E00 file.
That set contains The
disputed areas under the
country name IN1 and IN2
This dataset can not be
easily found at present on
the GRID Geneva site
http://www.grid.unep.ch/index.php?lang=en
in the same name.
may be it is still there
somewhere with some other name.
For copyright check the
metadata file which is here

All the shapefiles for

PoK and Aksai Chin as
part of India. Does
anyone here have access
to shapefiles that

looking to publish
(online) some maps, so
want to make sure that
it's accurate.
(I looked through the
group archives, and all
sources mentioned there
do not show these regions
as part of India)
Thanks
