 Hey Vaishnavi,
 That looks interesting.

 I've scraped the boundaries for the 6 cities, and put them here:
 https://github.com/datameet/PincodeBoundary

 At first glance, there are some oddities in the data, so I'll suggest
 that you cross check before using them.

Re: [datameet] Pincode Boundaries of India

[Vaidya]

Hi Gaurav,

562112 seems to point to Harohalli which is in Ramanagara district?
There is a new pincode map here that has some 562XXX codes that cover the
suburbs of Bangalore.
Hope this helps.

 FYI

 *#Pincode*

 I had spoken a week back to a friend from the Indian Postal service
 regarding pincode layers, here's what she replied :

 "We do not have an official map yet. Currently am working in geotagging
 all our post offices with delivery boundaries. We have geotagged 15
 post offices. Drawing pincode boundaries with ISRO. Hope to provide public
 access in 4-5 months."

 So will check with her again in August.

 *#Geocodes #GLC*

 On a related matter, I was wondering what the group's knowledge is on
 standardised codes for government properties. To explain - in the last
 couple of months I have been struggling with poorly specified addresses
 provided by Government authorities for purposes as diverse as Chennai rain
 shelter locations to assembly election polling booths. If the rain shelter
 information provided was maddeningly obfuscatory, the polling booth entries
 were uniquely different for the SAME polling station location. Extensive
 manual cleanup by volunteers had to happen before it could even be
 processed by the polling booth access audit app.

 My question is this :

 Surely as part of data.gov.in an initiative that standardises data
 collection codes across departments and ministries can be developed which
 will save everyone a lot of time and effort? So while the thrust would be
 on ALL government buildings initially - layers like schools, parks,
 post-office, revenue office, ration shop etc should be available on a drill
 down basis.

 So if one needs to reference a particular postoffice in rural Tamil
 Nadu - a code comprising standard census state, district downwards code +
 rural / urban indicator + administrative allotment (political, centre vs
 state cs Municipal vs panchayat) + purpose
 
 indicator + building particulars (toilet availability, parking facility
 etc)

 Something open and internationally standard on these lines with scope
 for evolution and addiition is what I'm imagining -
 http://vcgi.vermont.gov/sites/vcgi/files/standards/partii_section_j.pdf
 - does anything like this exist? Is it on the cards? What IS the
 international open standard adopted across governments?

 Looking forward to the group's thoughts / knowledge in this respect.

 Dear Avinash and all,

 I will try to make some time this week to scrape the pincodes from
 electoral rolls for all polling booths in my electoral GIS shapefiles.

 Since pincode is in latin script, this should not be affected by the
 much discussed PDF scraping issues with electoral rolls.

 We could then either go down the voronoi route, or alternatively use the
 heatmap processing chain that I used to generate AC boundaries - this
 latter would have the advantage of dealing with wrong coordinates in the
 booth point dataset (basically, not all electoral booth coordinates are
 correct; consequently, if we only voronoi, we would have a blip of
 pincode B within a see of pincode A quite frequently. The heatmap stuff
 takes care of this).

 Since I am not familiar with postal boundaries: can anyone here confirm
 whether pincode areas are contiguous, and whether each pincode has only
 one area? Or can it be that several non-contiguous areas have the same
 pincodem intersparsed with other pincodes? (In

Re: [datameet] Pincode Boundaries of India

[Vaishnavi Jayakumar (Inclusive India)]

Reminder in case anyone has inputs on this a year later - the geo-entities
standard bit.

ALSO - what is the latest feedback on postal GIS? Any feedback I could pass
on? In July 2016 it was still work in progress.

http://postoffice.umd.nic.in:8080/nicutility/#
FYI

*#Pincode*

I had spoken a week back to a friend from the Indian Postal service
regarding pincode layers, here's what she replied :

"We do not have an official map yet. Currently am working in geotagging all
our post offices with delivery boundaries. We have geotagged 15 post
offices. Drawing pincode boundaries with ISRO. Hope to provide public
access in 4-5 months."

So will check with her again in August.

*#Geocodes #GLC*

On a related matter, I was wondering what the group's knowledge is on
standardised codes for government properties. To explain - in the last
couple of months I have been struggling with poorly specified addresses
provided by Government authorities for purposes as diverse as Chennai rain
shelter locations to assembly election polling booths. If the rain shelter
information provided was maddeningly obfuscatory, the polling booth entries
were uniquely different for the SAME polling station location. Extensive
manual cleanup by volunteers had to happen before it could even be
processed by the polling booth access audit app.

My question is this :

Surely as part of data.gov.in an initiative that standardises data
collection codes across departments and ministries can be developed which
will save everyone a lot of time and effort? So while the thrust would be
on ALL government buildings initially - layers like schools, parks,
post-office, revenue office, ration shop etc should be available on a drill
down basis.

So if one needs to reference a particular postoffice in rural Tamil Nadu -
a code comprising standard census state, district downwards code + rural /
urban indicator + administrative allotment (political, centre vs state cs
Municipal vs panchayat) + purpose

indicator + building particulars (toilet availability, parking facility
etc)

Something open and internationally standard on these lines with scope for
evolution and addiition is what I'm imagining - http://vcgi.vermont.gov/
sites/vcgi/files/standards/partii_section_j.pdf - does anything like this
exist? Is it on the cards? What IS the international open standard adopted
across governments?

Looking forward to the group's thoughts / knowledge in this respect.

Re: [datameet] Pincode Boundaries of India

@veena

I did scrape the polling booth addresses in 2014 for Bangalore.
https://github.com/openbangalore/ps

For example, for Bangalore Rural

https://github.com/openbangalore/ps/blob/master/processed/Points_bangalore_rural.csv

It has the following columns
Latitude, Longitude, State, CEO_Name,
DIST_NO_NAME,DEO,AC_No_NAME,ERO_Name,PS_No_Name,BLO_Name

You can reverse geocode the street address using Lat, Long

Hi Veena
I may be able to help if you can clearly define the steps (not able to 
understand the kannada language). 
As far as i can see, pincode in the pdf is 6 digit number which can be easily 
grepped from pdf.The question is where is the polling booth name.

Re: [datameet] Pincode Boundaries of India

[Veena Ramanna]

Dear Raphael,

I understand that you have looked at Polling booth data. I am interested in
accessing the polling booth addresses for Karnataka state. Could you please
tell me if I can get that in the excel format ?

I have been able to access the polling booth names by clicking on each MLA
Constituency in each district at
http://ceokarnataka.kar.nic.in/FinalRoll-2017/Dist_List.aspx. However, we
have to click open pdfs at each of the polling booth names to get the pin
code.

Any help with this would be useful.

regards,
Veena

 Hi Raphael,

 Firstly, thanks a lot for extracting this information.

 I was looking at http://dx.doi.org/10.4119/unibi/2674065, but I could
 find only the Boundaries for the constituencies.

 Can you tell us where we can find the locations of the polling booths
 that you had extracted?

 Secondly, can you also share (if you still have them) the heatmaps code
 that you used to create the constituency boundaries? I think that is what
 will be required to create the pincode boundaries as well.

Dear Avinash,

I was looking at the pincodes_censuscodes.zip

in
the github at the location you have specified. This is helpful.

In addition to the pin codes, you have also been able to get gram panchayat
names. How have you managed that? Could you please tell me.

Re: [datameet] Pincode Boundaries of India

[Avinash Celestine]

Adding some relevant data.

The district handbooks released by census provide pincode details for
village areas. for each village / location code, they provide the relevant
pincode which covers that village. I have collated that data from the
handbook files and put them up here:

https://github.com/avinashcelestine/pincodes_censuscodes

Unfortunately, the district handbooks only provide such pincode data for
villages, not towns or wards. And even within villages, a number of
locations dont have the relevant pincode info (i think a large part of
Madhya Pradesh is blank for instance). Another bunch of villages have
pincodes in less than 6 digits. Despite these issues however, there are
still 4.13 lakh villages out of a total of 6.4 lakh, for whom six digit
pincodes are given.

the handbooks are here:
http://www.censusindia.gov.in/2011census/dchb/DCHB.html

(For the sake of completeness, i have not removed entries for those
villages for which pincodes are not given)

These will be useful for anyone looking to map census data to pincodes.

regards

Avinash

Hi Devdatta,

What is the data that you are looking for. 
I had saved it. 
But it is huge. About 1.55 GB consisting of about 135 shapefiles out of 
which 70 are raw booths.

Re: [datameet] Pincode Boundaries of India

[Raphael Susewind]

Hi Dev,

there are state/state.boothraw.* shapefiles, these should contain the
raw polling booth locations.

Heatmap scripts are terribly customized - I would have to look into this
myself, I am afraid, which could take some time (very busy)

You would have to go with voronois for now, sorry,

Best,
Raphael

Re: [datameet] Pincode Boundaries of India

[Raphael Susewind]

Dear all,

following up on my earlier email, I just pushed a list of pincodes for
all electoral booths across India to GitHub and made a pull request to
the datameet repository:

https://github.com/datameet/pincodes/pull/2

Please note that this can be incomplete, and is based on a rather
brutish, quick and dirty hack - see comments in rolls2pincode.pl. But it
does use the same IDs as those in the 2014 elections, and hence can be
combined with my GIS shapefiles for polling booths:

http://dx.doi.org/10.4119/unibi/2674065

I leave it to others to double-check accuracy and create actual pincode
maps. I hope this is useful,

Best,
Raphael

Re: [datameet] Pincode Boundaries of India

[Vaishnavi Jayakumar (Inclusive India)]

FYI

*#Pincode*

I had spoken a week back to a friend from the Indian Postal service
regarding pincode layers, here's what she replied :

"We do not have an official map yet. Currently am working in geotagging all
our post offices with delivery boundaries. We have geotagged 15 post
offices. Drawing pincode boundaries with ISRO. Hope to provide public
access in 4-5 months."

So will check with her again in August.

*#Geocodes #GLC*

On a related matter, I was wondering what the group's knowledge is on
standardised codes for government properties. To explain - in the last
couple of months I have been struggling with poorly specified addresses
provided by Government authorities for purposes as diverse as Chennai rain
shelter locations to assembly election polling booths. If the rain shelter
information provided was maddeningly obfuscatory, the polling booth entries
were uniquely different for the SAME polling station location. Extensive
manual cleanup by volunteers had to happen before it could even be
processed by the polling booth access audit app.

My question is this :

Surely as part of data.gov.in an initiative that standardises data
collection codes across departments and ministries can be developed which
will save everyone a lot of time and effort? So while the thrust would be
on ALL government buildings initially - layers like schools, parks,
post-office, revenue office, ration shop etc should be available on a drill
down basis.

So if one needs to reference a particular postoffice in rural Tamil Nadu -
a code comprising standard census state, district downwards code + rural /
urban indicator + administrative allotment (political, centre vs state cs
Municipal vs panchayat) + purpose

indicator + building particulars (toilet availability, parking facility
etc)

Something open and internationally standard on these lines with scope for
evolution and addiition is what I'm imagining -
http://vcgi.vermont.gov/sites/vcgi/files/standards/partii_section_j.pdf -
does anything like this exist? Is it on the cards? What IS the
international open standard adopted across governments?

Looking forward to the group's thoughts / knowledge in this respect.

Vaishnavi

Re: [datameet] Pincode Boundaries of India

[Raphael Susewind]

Dear Avinash and all,

I will try to make some time this week to scrape the pincodes from
electoral rolls for all polling booths in my electoral GIS shapefiles.

Since pincode is in latin script, this should not be affected by the
much discussed PDF scraping issues with electoral rolls.

We could then either go down the voronoi route, or alternatively use the
heatmap processing chain that I used to generate AC boundaries - this
latter would have the advantage of dealing with wrong coordinates in the
booth point dataset (basically, not all electoral booth coordinates are
correct; consequently, if we only voronoi, we would have a blip of
pincode B within a see of pincode A quite frequently. The heatmap stuff
takes care of this).

Since I am not familiar with postal boundaries: can anyone here confirm
whether pincode areas are contiguous, and whether each pincode has only
one area? Or can it be that several non-contiguous areas have the same
pincodem intersparsed with other pincodes? (In which case voronoi would
perhaps be the better solution at last)

In any case, I hope to give you the pincode for each polling booth by
end of the week or so (based on all-India 2014 electoral rolls),

Best,
Raphael

Re: [datameet] Pincode Boundaries of India

[Avinash Celestine]

perhaps one way is to avoid using postal data altogether.

All header pages in electoral rolls(the first page) contain the name of the
polling station related to that roll, the PS number, and importantly the
pin code.

 A site like psleci.nic.in has geog coordinates of polling stations (though
Raphael had collected the data earlier*). Matching the two will give a
fairly dense scattering of points  - in fact much more dense than if we
used some of the methods earlier in this thread.

We thus have a way of associating a pin code with a geo coordinate. We can
then use the voronoi method.

Electoral rolls are mostly in pdf which make them difficult to scrape. But
from what i have seen, for any given state, the location on the header
page, of the pincode number is more or less constant, making it possible to
target just that part of the page with any pdf parser.

Electoral rolls have become difficult to download in bulk( a good thing!)
but i understand different people on this group have the pdfs for different
states. Putting this stuff together should give us comprehensive data on
header pages for atleast some states. Alternatively, we can file RTIs for
just the header pages of electoral rolls, though i dont know how successful
that would be.

Re: [datameet] Pincode Boundaries of India

[srinivas kodali]

Well, There were postal delivery zones in the past and the postal
department even used to make maps of these zones. The Delhi postal delivery
zone map

had
boundaries for delhi. I am not sure if other cities had them or how long
the postal department was doing this, but it certainly can help with the
boundaries for cities.

Re: [datameet] Pincode Boundaries of India

[Arun Ganesh]

Shravan, crowdsourcing the boundaries of pincodes is not as trivial as you
think. To start with, an area does not fall under a pincode, rather a
street does based on the post office that services it. Read this:
http://www.georeference.org/doc/zip_codes_are_not_areas.htm

You may also want to do some background reading of existing research that
has been done by the group here:
https://datameet.hackpad.com/M4hPFJVV2Gm?eid=v4YoXN4tTw5

To sum up, nobody has precise pincode boundaries like how you imagine them,
not even the postal department. Any existing datasets are an estimate at
best using some data processing on a large volume of address data.

Thank You guys. I think we should use the power of crowd sourcing /
community project to define these boundaries on OpenStreetMap. Any
suggestions are welcome.

Thanks,

 Hi Shravan,

 You can get them either from gadm[1] where there are some restrictions
 on the use of data or from OSM boundaries[2] site where the data is
 available under ODbL. But I'm not sure whether Tehsils of all Indian states
 have been mapped in OSM and also gadm data may not be complete/accurate.

Tehsil/Taluk boundaries are a union of respective revenue village

Re: [datameet] Pincode Boundaries of India

I would think that the tehsil/taluka boundaries would be a union of
respective village/town boundaries.

Re: [datameet] Pincode Boundaries of India

[Yogesh]

Hi Shravan,

You can get them either from gadm[1] where there are some restrictions 
on the use of data or from OSM boundaries[2] site where the data is 
available under ODbL. But I'm not sure whether Tehsils of all Indian 
states have been mapped in OSM and also gadm data may not be 
complete/accurate.

cheers,
yogi

Re: [datameet] Pincode Boundaries of India

[shravan]

Thanks guys!

I think we can start a community project to build these boundaries. How
about using OpenStreetMap to trace these boundaries. Ideas, suggestions are
welcome.

Thanks Raphael, I think I'll use the point to polygon method for now.

Thanks,
Shravan

[Raphael Susewind]

Hi Shravan,

another option - depending on what you are after - could be to use
Devdatta's point data for post offices, voronoi it into polygons, and
aggregate by pincode - that might not be the same as official
boundaries, but the closest you can get (each locality in India would be
assigned to the most proximate postoffice...)

Best,
Raphael
