Btw, the portal he mentioned was the "Gati Shakti" portal (that supposedly 
uses LGD codes)

[datameet] LGD codes = Census 2011 codes?

[Sharad Lele]

Folks, today in a meeting at Ministry of Tribal Affairs, the Addl Secy said 
that "the new portal for tracking benefits to tribal villages is using LGD 
codes, and henceforth all other data should be linked to these codes"

Now, I presume LGD=local govt directory codes. But when I look at data 
shared by various folks via datameet, I see that the LGD codes are the same 
as Census 2011 codes. Am I right? or is there a more exhaustive list of 
'settlements/hamlets' with some longer/different code?

[datameet] Sorting Devanagari lists correctly in Excel

[Sharad Lele]

So if I have a list of village names entered in Devanagari font in an Excel 
column, and I try to sort that list, it does a 'sort of okay' job, but 
goofs up in at least one way: it puts अं before अ , so अंबिकापुर comes 
before अकोला , when in fact it should come afterwards.

Has anyone encountered this problem? Any solutions?

Re: [datameet] Creating variable names in Devanagari

[Sharad Lele]

Hi Nikhil, Ujaval, and others who responded:
Shiv, my colleague who handles our webgis, tried importing the geopkg
version (which was storing and displaying Devanagari variable names in
QGIS) into postGIS. He says "I used the normal pguploader, shape2posrgis,
and ogr2ogr method". But reports that postGIS does not accept those
variables.

Any workarounds?

Re: [datameet] Creating variable names in Devanagari

[Sharad Lele]

Thanks, Ujaval. Yes saving as .geopkg works (saves the field names in full 
and displays properly upon reopening). This is the only solution that has 
worked so far.

But I am not sure this is going to work for us in this particular situation 
where we are then using the file in postGIS to display in a webGIS. Let me 
ask our webGIS person.

Just to clarify/muddy the situation: I am able to enter long Devanagari

[datameet] Creating variable names in Devanagari

[Sharad Lele]

Hi folks, I am using QGIS and I want to create variable names in Devanagari 
(for instance जिला instead of District). If I create a new column in the 
attribute table and enter the column name in Devanagari using Microsoft 
Indic Language Tool on my computer, it seems to work (जिला is shown as the 
column name). But the moment I save the edits and reopen the attribute 
table, this gets truncated into something like जिल?. The last character is 
not really a question mark, something more complex. 

Any suggestions for making the column names appear and save properly in 
Devanagari? (The same would be true for Kannada or other scripts, I am 
sure).

[datameet] Google Earth historical imagery disappeared?

[Sharad Lele]

Folks,
Over the last few days, it appears as if Google has removed all historical 
satellite imagery for India for the 2000-2019 period. Just last week, I was 
using imagery from 2005 and 2003 for our field sites in MP and 
Chhattisgarh. But as of this weekend, there is NO historical imagery 
between 1985 and 2019! I have checked several different locations in India.

Can others confirm this? This is a huge loss for us and the wider 
public--e.g., historical imagery is crucial in the implementation of the 
Forest Rights Act. Is there a way we can ask Google to reinstate the 
imagery?

Sharad

Re: [datameet] Re: Looking for list of census village names for CG and MP in Devanagari

But btw, there is an option on the main PRD website to switch to Hindi, and 
when I do that, then when I go searching for specific Gram Panchayats, I do 
get this search menu, which suggests that at the backend somewhere the 
Hindi lists also exist? Any ideas?

[datameet] Looking for list of census village names for CG and MP in Devanagari

I am looking for the census village list for Chhattisgarh and Madhya 
Pradesh (for starters) in Devanagari (Hindi script). Preferably with Census 
2011 codes, so that I can quickly match them to the Census dataset, which 
is in English. But even if no codes attached, an accurate list with 
tehsil/block and district tags in digital format (not pdf hopefully) will 
be a big help.

Any suggestions, folks?

Re: [datameet] Re: Survey of India published - District, Block and Village Boundaries

[Sharad Lele]

Thanks Craig for locating this dataset. Potentially solves all our 
problems. Yes, can add only one district at a time to the Shopping Cart, 
but can in theory keep going back and adding more items to the Cart (I did 
2 at a time). Process for checking out and creating downloads involves many 
clicks... bit idiotic. But some substantive limitations after I downloaded 
and checked Dindori in MP:

1. Village boundaries do match latest village shapes from revenue layers, 
BUT they are east-shifted by 200m (they must have goofed the datum)
2. Polygons don't have any census ID, so linking to other data will require 
adding those manually (!!) or figuring out what numbering system SOI has 
used. Any thoughts on that?
3. I tried Andhra Pradesh two districts Vizag and Srikakulam, and it says 
"data not available yet". So the dataset is still in the making. Not sure 
what is available and what is not, overall.

Has anyone tried this website:
http://mrsac.maharashtra.gov.in/cadastralgis/

It seems to require login and password. Can anyone get a login? If not, 
does anyone in this group have access? we are looking for some maps of 
Chandrapur district that are not available on Bhunaksha.

Re: [datameet] Shape files for Bhopal, Khandawa, Omkareshwar along with villages boundaries

[Sharad Lele]

Hi Akshit: I tried this link because I also want accurate village 
boundaries for MP. But the link does not work: first it does not accept 
even spaces between first name and last name etc. And finally when I had 
that figured out, clicking the submit button led to an error (crash) 
message. Have you or anyone else successfully submitted a request and 
actually got vector data from MP govt?

Re: [datameet] State-->District-->Village level data

[Sharad Lele]

Thanks, KK.
I checked this out. Apart from the fact that it is not downloadable, I find 
that the layer has many errors. Lots of generalization of boundaries and 
actual errors in locating villages... :-(

Just sharing my observations for others to be aware of...

Re: [datameet] State-->District-->Village level data

[Sharad Lele]

Go to https://mpbhulekh.gov.in/mpbhulekh.do and choose 'land parcel map' 
from the dashboard on the home page (have to scroll to right).

MP used to have a Bhunaksha portal like other states, but they seem to have 
purposely disabled it!

 Hey All,

 I am trying to get village information for all states in India.
 I found the district, subdistrict and village data from the 2001

 Can you please point me to any API or website that I can use to get 
 this information?
 For villages the coordinates would be enough.
 Also wanted to figure if there is any specific code that is 
 maintained per village?

Re: [datameet] Re: global 10 m landuse data

[Sharad Lele]

Since several folks emailed me one-on-one, I am adding this clarification:

1. The link below only gives information on what the map is about, how it 
was made, and (importantly) what its accuracy levels are.
https://www.arcgis.com/home/item.html?id=d6642f8a4f6d4685a24ae2dc0c73d4ac

2. To actually download tiles for your area, you need to go to the 
downloader page, which for some reason does not seem to work from the above 
page. You need to go to:
https://www.arcgis.com/apps/instant/media/index.html?appid=fc92d38533d440078f17678ebc20e8e2

3. You can also download the whole set of tiles at once (60GB) 
https://soilspackage-useast.s3.amazonaws.com/EsriLandCover/GlobalEsri2020LandCover.zip

4. Upon perusing the documentation, and doing some ground truthing of my 
own for areas I have already mapped at high resolution, my observations are:
a) the 10-fold classification is generally too coarse for many 
applications. E.g., 'trees' includes horticultural plantations (coconut, 
areca, eucalyptus, rubber, coffee, etc) along with forest of all densities 
and types. 'cropland' includes fallows.
b) the documentation itself acknowledges that the accuracy for certain 
classes is low (~50%): grassland, and scrubland. Thus, most forest edges 
are classified as 'bare', when they are likely to be grassland or scrubland.
In other words, the spatial resolution may be good, but the 
class-resolution (and associated accuracy) is not good enough for many 
applications. Not a criticism of this effort, but something to keep in mind 
when using the product.

Again, a big thanks to Justin for bringing this source of data to our 
attention and hosting links on his website 
(https://revolutionarygis.wordpress.com/) which has tonnes of other goodies 
as well!

Best,
Sharad

[datameet] Downloading Survey of India topos (Open Series)

[Sharad Lele]

I thought SOI had put out topos for all of India in the Open Series for 
public download.
But when I visit this page: 
https://surveyofindia.gov.in/pages/open-series-maps-osm
I find many states are missing in the list: Kerala, Tamil Nadu, Jharkhand, 
etc.

And when I visit the download page
https://soinakshe.uk.gov.in/mtr/

I am unable to register as a new user (no OTP forthcoming) to download even 
what exists (assuming the two pages are talking about the same thing).

What is the experience of other users? Am I looking at the wrong pages!

[datameet] Re: Census land use categories 2011 vs 2001

[Sharad Lele]

I think I found the answer to my own question: In a District Census 
Handbook of 2001:
*Column 20 and 21 shows area irrigated by different*
*sources of irrigation and un-irrigated area. These two*
*columns cover all agricultural land which equals to net*
*cropped area sown with crops and orchards including*
*current and other fallow lands. In case of irrigated*
*land, the source of irrigation has also been indicated.*

This means that "Fallows other than Current Fallows" and "Current Fallows" 
of 2011 are part of NSA in 2001.

BUT, the next para in the 2001 handbook then creates confusion again:
*Column-22 Culturable waste : This includes all*
*lands available for cultivation whether not taken up*
*for cultivation or taken up for cultivation once but not*
*cultivated during the five years or more in succession.*
*Such lands may be either fallow or covered with shrubs*
*and jungles which are not put to any use.*

Now what does one make of this?

[datameet] Census land use categories 2011 vs 2001

[Sharad Lele]

Dear All,
As you know, Census Village Amenities Tables (now called Village 
Directories) contain a huge amount of data on various attributes of 
villages. Of particular interest to me is the last set of columns, which 
are about land use in the village. Till Census 2001, there used to be a 
limited number of categories of land use: 4 main categories (forest, area 
not available for cultivation. culturable waste, and Net Sown area (NSA was 
given in two columns: irrigated land and unirrigated land).

In the 2011 census, they have moved to the 'standard' 9-fold 
classification: forest,  
Area under Non-Agricultural Uses, Barren & Un-cultivable Land, Permanent 
Pastures and Other Grazing Land,  Land Under Miscellaneous Tree Crops 
etc., Culturable Waste Land, 
Fallows Land other than Current Fallows, Current Fallows, Net Area Sown, 
Total Unirrigated Land, Total Irrigated land. (Note that irr and unirr are 
subcategories of NSA). Plus they have given breakup of irrigated land by 
source.

The question I have for you is: how do these 9-fold categories map onto the 
old 4-fold classification? 
Forest 2011 to forest 2001, 
Barren+AreaunderNAU in 2011 = area underNAU in 2001
Misc Tree Crops+Cult Waste+Permanent Pastures in 2011 = Culturable Waste in 
2001
And Total Unirr + total Irr in 2011 = total unirr + total Irr in 2001

But then what happens to current fallows & long-term fallows?? Where were 
they included in 2001 ? Under Unirr? or under Culturable waste ?

Appreciate your help. Could not find any online documents explaining this.

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[Sharad Lele]

I think Thejesh's idea of a joint response is excellent, and am happy to 
contribute.
My immediate observation is that 
a) the RS policy does not cover drones/UAVs, which according to me is the 
hot area, where a lot of application development is also required. The UAV 
related policy by DGCA is purely regulatory (what permissions are required 
etc), not developmental
b) the opening of 5.6m imagery is great. HOWEVER, there is lack of clarity 
of whether the govt will continue to support the IRS P6 (or equivalent) 
programmes well into the future. There is no clear commitment. There is 
talk about past images, and open sharing, but obviously if commercial 
players come in, their data will not be shared. So a bit more clarity on 
whether (like USA) the state agency will continue to do imaging till 5.6m 
resolution and leave the 5.6m to 1m field for commercial providers is 
required.
c) the shift from NRSC to a socalled PSU is noticeable and its implications 
unclear. What we do know as users is that NRSA is not particularly 
accountable to users in terms of quality of data, transparency in what they 
do (they will suddenly stop taking requests for imaging on particular 
dates, saying they are doing a full run for govt), technical transparency 
(quality), and promptness. And it is not clear in the policy how this 
accountability will be enforced vis-a-vis the PSU either.
d) The USA defines 'high-res' as 0.5m and below. That's why commercial 
providers stop at 0.6m. (please correct me if I am wrong--or if this is 
outdated). We should use the same threshold, not 1m. Because otherwise our 
data users are unnecessarily penalised, while 0.6m data on India are 
available to users located in the USA or elsewhere!
e) accountability of the high-res committee--they simply turn down requests 
without any reason. Who holds them accountable?
f) If commercial providers are to come in from India, how will they beat 
existing global suppliers of 1m data such as Ikonos and others who are well 
established? 

Some quick thoughts, to spark further debate in the group and help in the 
drafting of the joint comment.

Re: [datameet] DOS release Remote Sensing Policy 2020 draft for public comment

[Sharad Lele]

I agree with you, Ujaval. Getting 5.6m data in the public domain will be a 
big boost. 

But I am curious to know from others what their experience has been with 
the quality of this 5.6m (IRS P6) data. For instance, I found the spectral 
quality to be rather poor: it boasts of being 10-bit but all the data are 
clustered in a 7-bit space. So we had to go back to coarser Landsat-8 
because it gave better spectral quality (not just more bands).

On the rest of the policy: I am wondering why they say nothing about 
drones, about UAV-based LIDAR, and so on, which are really the cutting-edge 
these days, are they not?

[datameet] Older Census handbooks

[Sharad Lele]

Folks, till recently, I used to access older Census Handbooks (1981, 1991 
and even earlier) from this link:

lsi.gov.in:8081/jspui/handle/123456789/1


Now this link has stopped working. Any suggestions? Alternate links? 
Corrections?

Thanks.

[datameet] Re: 2001 village and town boundaries

[Sharad Lele]

Dear Mark,
Happy to know about your interest. I am also quite interested in these 
issues, having worked on 1991, 2001 and 2011 census datasets and their 
spatial representation (at least for Karnataka and some other states). 
There are many issues, both with the census datasets themselves and with 
the spatial boundary datasets released by Meiyyappan et al. I may not be 
able to lay out everything immediately, because of being in the throes of 
some deadlines, but hope to go through your writeup and respond a bit 
later--maybe mid-June, if that is okay with you.

Best,
Sharad

[datameet] Re: BhuNaksha: source of cadastral maps

[Sharad Lele]

Dear All,
A followup question addressed to everyone on the DATAMEET group:

Can someone write code to help download a large number of cadastral maps 
from a Bhunaksha website (in our case Chhattisgarh)? As you know, the 
website /portal is awkwardly organized: not only are the maps in png format 
(which is okay) but they don't have individual file names, and one has to 
access each village separately by choosing it from a list within a taluka 
(and within that some Revenue Inspector category).

Can someone write code to download and tag a bunch of maps automatically? 
Say for one whole taluka?

Sharad

[datameet] State GIS Portals

[Sharad Lele]

Found this website from where you can reach most of the state GIS portals:

The state portals appear to have a similar format, with some variations. 
Nothing is downloadable (of course!).

[datameet] Chhattisgarh village layers online (webportal)

[Sharad Lele]

Just sharing that, just like the Maharashtra GIS portal 
(http://mrsac.maharashtra.gov.in/geoportal/), a portal for Chhattisgarh 
seems to be up and running

https://stategisportal.nic.in/stategisportal/Chhatisgarh_BharatMaps/map.aspx

It is way more clunky than the MRSAC one (don't know how CG got some 
e-governance award for this portal), but still, something better than 
nothing. Displays village boundaries.

If anyone can figure out a way to download the village boundary layer, 
please post.

I have discovered a source of cadastral maps for several states. This is 
mostly under the BhuNaksha initiative of NIC. They seem to have created 
separate websites for each state. Don't know for how many. I have found:

Maharashtra: https://mahabhunakasha.mahabhumi.gov.in/bhunaksha/27/index.jsp
Madhya Pradesh: http://www.mpbhuabhilekh.nic.in/
Chhattisgarh: https://bhunaksha.cg.nic.in/#home-pane  (DOES NOT WORK RIGHT 
NOW)
Odisha: http://bhunakshaodisha.nic.in/bhunaksha/

The BhuNaksha websites have a common format: you can choose district, 
taluka and village, and then the village cadastral map shows up (its in png 
format). You can click on a plot/parcel, and it will show the details of 
that plot: area, owner name, etc. You can generate  pdf report for that 
parcel. 

Maharashtra version had added ability to show you the cadastral map in 
geo-rectified mode on top of a google-earth-like satellite image--quite 
useful.

CATCH: a) the names of district, taluka, village etc are IN THE STATE 
SCRIPT: so devanagari for MP & Maha & CG, but Odiya for Odisha. So if you 
don't read that script--you are sunk
b) in most states (except Maharashtra!), it is not enough to know the 
district, taluka and village name. Within a taluka, you have know Revenue 
Inspector and then something called 'halka', and then choose from the 
villages within that halka. If you don't know this (RI and halka), you have 
to do brute force: search in each halka in each RI! (typical sarkari 
rubbish: not wanting common people to actually use the website!).

Karnataka seems to have its own initiative: 
https://www.landrecords.karnataka.gov.in/service3/
Here, you can actually download pdfs of each cadastral map, and in some 
cases, even the KML! And searching for the village is district, taluka and 
then village.

Hope this helps.

I am sure there are more such websites for other states. Please look up and 
share.

Re: [datameet] Re: India Shape Files

[Sharad Lele]

Arjuna and others: These are layers that one can view via GoogleEarth, but
not really downloadable right? Like I tried to look at the Kodagu lulc
layer. Seems reasonably accurate. But don't know the year or the legend.
Where would this info be? and is there a way to download the layer as a
shapefile?

Re: [datameet] Re: Correct CRS for datameet maps

[Sharad Lele]

Devdatta's summary was short and sweet, and practical. To add to it: 

1. The NNRMS CRS suggested seems to be in Lambert Conformal Conic 
projection (with WGS84 ellipsoid and datum). An alternative to it is the 
UTM projection system, which keeps longitudes parallel, and gives 
reasonably accurate area estimate. The particular UTM zone one may use 
varies by which part of India one is in.
2. In common parlance, 'unprojected' means having no Coordinate Reference 
System at all. In GIS parlance, 'unprojected' may be understood as 
'geographic' CRS, that is, in lat-long rather than in metres. I presume 
Ashim means 'having no CRS' at all. Whether one's map needs a CRS or not 
depends upon what use one wants to put it to (and hence how accurate it 
must be) and its size. A map of a 60'x40' piece of land does not require a 
CRS if the purpose is house construction. It may require a CRS if one is 
setting up a telescope on it which will do interferometry with another 
telescope 500km away. A map of even a layout or a village or small town may 
not need a CRS if one wants approximate locations/directions to navigate 
visually (old style). It will need a CRS if one wants to use a GPS to 
navigate.
If, Ashim, you mean 'geographic' vs 'projected' system, the answer is 
different: geographic is useful for representation, easy to understand 
(lat-long concept), but not to be used for calculating distances and areas.

Hope this helps. Devdatta and others: please correct/supplement.

Hi Thejesh: Correct me if I am wrong: This seems to be a map only of the

very useful too.

[datameet] Re: Sharing : Census 1991 _Village/Town Level PCA Data

We have been able to convert the SAS files for 1981 district data from 
Vannemann into csv files using R. I have posted them here. But cannot make 
out the format, because it seems quite complicated. You may have to refer 
to the codebook on the website. Also there may be errors in data

Sorry, I should have clarified: the red boundary is SOI official release, 
the black one is GADM.

Re: [datameet] Re: GIS Ward Maps for Hyderabad, Kolkata and Ahmedabad

[Sharad Lele]

Dilip,
I was going to ask you earlier: what is the difference between Census Wards 
and Municipal Wards? My understanding is that the wards are always the 
same, only Census Enumeration BLOCKS are unique to Census operations. They 
are tiny portions of each ward.

Re: [datameet] Re: GIS Ward Maps for Hyderabad, Kolkata and Ahmedabad

[Sharad Lele]

May I request everyone who has ward boundaries to please upload them to the 
Github repository that Thejesh has created and repeatedly shared links for? 
That way, we don't have to keep making these individual requests, and the 
whole community has access to these datasets at any future point also. 
Please help build this common property resource.

[datameet] Re: Updated Taluk Shapefile!!

[Sharad Lele]

I am wondering if Hubli-Dharwad MCorp can be considered as a separate 
taluka. Even Bengaluru MCorp is divided across two taluka (Bangalore south 
and Bangalore North). H-D needs to show up as polygons when one goes to a 
village boundary map...

Re: [datameet] Village boundaries map for Odisha

[Sharad Lele [शरच्चंद्र लेले]]

% to eeven 
200 % of the aera as per revenue department.


The I took a map from Justin (on our group) for that area. It had many 
missing villages. After several days of retracing on Google Earth I 
created a better map.

But it was time consuming just for 125 Villages.

There are several issues

1. No one actually has correct georeferecned accurate enough boundaries.
2. Whatever is available is just the correct (to an extent) 
juxtaposition of villages.

3. Sometimes the Uninhabited villages are missing as in 2001 census Data.
4. It sis not necessary that the Habitation of a particular villages 
is within the Revenue boundary of that village.
5. Sometimes the habitations merge between two villages to form an 
apparently single village.



Better and more accurate village maps can only be created IMO by 
having at least ONE POINT inside  a Khasara or a survey number 100% 
accurately mapped and them merging them to get a Revenue village map.

For large units of Survey numbers we will need More than one points.


I am pessimistic about we ever achieving that accuracy in India.
Because I have seen that even in a Specific Project based PAID Survey 
assignment  for Engineering applications some surveyors FUDGE the data.


There could be Good quality work in some pockets but when you mix Good 
Quality and Bad quality then the end result is bad quality and not 
average quality.


We need to realise that.

Re: [datameet] Re: Census codes 2001 and 2011

[Sharad Lele [शरच्चंद्र लेले]]

Dear Dilip:

Just to add to my public message: I had independently purchased the 
code-conversion tables (2001 to 2011) from Census. And have given a copy 
to Thejesh to upload to github. So it should be up there soon, in case 
the ones sent by Mishra don't work for some reason (they are identical 
as far as I know)

Hello,

is there any  logic or data to link the village census codes of
2001 and 2011. Or they are completely different.

It appears that there is no way to link the codes which IMO is a
blunder in this computer age.

If there is a mapping between the codes anywhere please let me know.

[datameet] Re: Census codes 2001 and 2011

[Sharad Lele]

Folks, 

Sumit Mishra had posted this earlier:

Justin/Sharad,

Please follow this link to get the files (both in Stata format named - 
rdir/udir).
https://www.dropbox.com/sh/t7d3sy9sage8hoz/AABogZUrrWj-6uyFFy2T8mcna?dl=0
Use this dataset with caution. I had only worked on a subset of this- 
Maharashtra- and found some coding errors.
Let me know if you have any other question.

Thanks,
Sumit

[datameet] Re: GIS analysis

[Sharad Lele]

@Nagesh: I strongly endorse Dilip's warning. And I would add another 
question: One needs to be clear what one is trying to find out (question 
comes before tool) and whether the answer is already approximately known 
before hitting it with a tool that has all the limitations Dilip mentions. 
So what is the question?

For instance, we already know that the installed STPs don't operate at full 
capacity and that the problem is largely to do with clogged UGDs, broken 
UGDs and incomplete UGDs. E.g., Vrishabhavathy Valley STP has installed 
capacity of 180 MLD. One of the units does not work, so effectively 120 
MLD. But even this 120 MLD consists of only 20-25 MLD of raw sewage coming 
from the UGD, rest is diluted sewage being picked up from the river. We 
have a published paper on V-Valley STP (mal)functioning.

We also know that even as K valley STP capacity is being upgraded, it 
gets some of its sewage (60MLD) by pumping from the Agara side and will get 
another 100 MLD pumped from Ejipura drain (pickup point several km before 
drain reaches Bellandur).

So any simple terrain-based analysis is pointless when on the one hand 
gravity-based movement is blocked by clogged UGDs and on the other hand 
pumping moves sewage around.

[datameet] Re: India Village Boundaries for all states

[Sharad Lele]

As far as I can see:
a) the maps only show state, district and taluka boundaries, no village 
boundaries
b) the maps are not downloadable.

Others please comment.

Yes, but just the boundary, not wards inside the towns/cities.

Also note that for some funny reason quality of the maps (i.e., 
fuzziness/sharpness) seems to vary from state to state. MP has posted its 
atlases on its own website 
(http://censusmp.nic.in/censusmp/atlas02-09-13.html) and these are the best 
quality I have seen so far.

[datameet] Statewise Administrative atlases 2011 are now online

[Sharad Lele [शरच्चंद्र लेले]]

http://www.censusindia.gov.in/2011census/maps/atlas/administrative_atlas.html

They contain maps and lists for each taluka, with the maps showing 
village boundaries. This at least enables us to understand where a 
village listed in the census 2011 PCA or DCHB tables is actually located.

[datameet] Fwd: Fwd: [New post] Happy Independence Day and Open Indian Village Boundaries

[Sharad Lele [शरच्चंद्र लेले]]

For some reason, this email by Thejesh did not show up datameet (or 
maybe I just missed it?). So forwarding it to the group.


Thejesh, thanks for this. I have two queries:

1. Is this effort different from the effort by Nisha? My impression was 
that we had (with the group) access to boundaries of many more states, 
but the issue was copyright etc, and that Nisha, you and some others 
were taking legal opinion on the same. Is what you have put out a result 
of that? What is the legal opinion?


2. I think I have asked this silly question on the group before, but 
have to ask it again: what is the 'json' format, and why is it better to 
put the data out in that format than in .shp? And how does one convert 
from json to .shp?


Thanks.
Sharad

   Happy Independence Day and Open Indian Village Boundaries
   


by Thejesh GN 

One of the longest and most passionately discussed subject on the 
Data{Meet} list is the availability of Indian Village Boundaries in 
Digital format. Search for Indian Village shape files 
 
and you can spend hours on reading interesting conversations.


Over last two years different members of community have tried to 
digitize 
 
the maps available through various government platforms or shared the 
maps through their organizations 
.


A look at the list discussion tells you that boundaries of at the least 
75% of the states are available in various formats and quality. What we 
need at this point is a consolidate effort to bring them all on par in 
format, attributes and to some level quality. So some volunteers at 
Data{Meet} agreed to come together, clean up the available maps, add 
attributes, make them geojson and publish them on our GitHub repository 
called Indian Village Boundaries 
.


Of course this will be an on going effort but we would love to reach a 
baseline (all states) by year end. As of now I have cleaned up and 
uploaded Gujarat. I have at the least 4 more states to go live by month 
end. Karnataka, Kerala, Tamil Nadu and Goa. I will announce them on the 
list as they go live.


The boundaries are organized by state using state ISO code. All the 
village boundaries are available in geojson (WGS84, EPSG4326) format. 
The project page  
gives you the status of the data as we clean and upload. Data is not 
perfect yet, there could many errors both in data and boundaries. You 
can contribute by sending the pull requests. Please use the census names 
when correcting the attributes and geojson for shapes and but please 
source them to an official source.


Like everything else community creates. All map data will be available 
under Open Data Commons Open Database License (ODbL) 
. This data is distributed in 
the hope that it will be useful, but WITHOUT ANY WARRANTY; without even 
the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR 
PURPOSE. If you find issues we are more than happy to accept corrections 
but please source them to an official source.


On this 70th Independence day, as we celebrate the historic event of 
India becoming Free and Independent, Data{Meet} community celebrates by 
cleaning, formatting and digitizing our village boundaries. Have a great 
time using the maps and contributing back to society.

Hi folks,
I believe Nisha Thompson and Thejesh were trying to figure out the legal 
dimensions related to posting these boundaries on our group. Maybe Nisha 
can give us an update on where things stand?

[datameet] Re: India Shape Files

[Sharad Lele]

Looks like a webGIS platform created by Gujarat State Remote Sensing Agency 
called BISAG. 

It would be wonderful if one could get access to the village layer, 
especially for Jharkhand, Chhattisgarh, etc. It is visible, but as usually, 
tightly protected.

 Does anyone have shapefiles of Karnataka districts (priority) and

 Separately, does anyone have shapefiles of the boundaries of various

 I know that Thej started the wonderful Open Bangalore, and it currently

Re: [datameet] Re: Map Digitalization Effort

[Sharad Lele [शरच्चंद्र लेले]]

Dear Dilip:

the projection depends upon the source. In most cases, the only source 
that exists is the Census district handbook maps. These in turn have 
been prepared from taluka level maps that the Directorate of Land 
Records and Survey Settlement creates from village-level cadastral maps. 
Now this method by definition means there is no original projection 
system, and that these maps are not geo-corrected (not 
terrain-corrected) as the originals are based on chain survey and plain 
table surveys, not theodolite surveys. So unless someone has done some 
correction work before creating the maps you used, they would have 
significant limitations in terms of geo-referencing. Our experience (we 
created the Karnataka layer from scratch, by digitizing the individual 
taluka-level village boundary maps by hand) tells us RMS errors of 2-3km 
for the state as a whole would be normal. What we did was to 
georeference by matching the state boundary so created to the Survey of 
India state boundary, which is available and is a properly projected 
layer. (Simply creating a prj file for the existing map does not work, 
because the scans will be anyway in centimetre or mm or inch units. So 
you need pucca geo-rectification.) Fairly easily done in QGIS.


I hope this helps. Am still digging for the layers we supposedly have.

Hi,

I think I will share the data anyway after doing some checks. I am not 
attempting the attribute linking right now because that will be a 
bigger effort.


I tried to georeference it.
My approach was as follows.
So far I have not used any transformations which distorts the shape as 
it was in the PDF file.
I imported each district separately and have been able to match them 
with each other to make the whole of Gujarat using only MOVE, SCALE 
(EQUAL XY) and ROTATE.

Practically I used the Autocad ALIGN command.

Which means I have exactly same shape as in PDF files.

Then I thought I will guess the original projection and see if it 
matches and then reproject it rather than Doing any 
rubbersheeting/other arbritrary distortions to shape.


I tried LCC projection for India , UTM 43N, and LL84 in that order. 
They do not seem to match.


Anyone may suggest any other possible projection.

Otherwise I will check it and share it as it is.

This is the summary of the Data :

33 districts : 114 Polylines in Autocad (because of Islands and enclaves)
379 Taluka Polylines
20128 Village polylines
15804 Text names
16137 Markers manly the Village dot.

freeing sets of maps.

What do you all think?

Re: [datameet] Re: Map Digitalization Effort

[Sharad Lele [शरच्चंद्र लेले]]

I am hoping to lay my hands on old (1991) village boundary layer maps 
for many states.


We should probably focus our energies on Town Ward boundary maps--these 
are the hardest to get.


Copyright: I would not worry about this---this has to be public 
information...

Hi,
What are the copyright / legal issues in reverse engineering these 
maps and sharing them back publicly.


I have checked the maps On the link Bihar and Gujarat seen to be good 
because they are vector and have layers which can be reverse 
engineered as separatr layers. Rajiv Gandhi awas yojna maps are raste 
rand are practically useless.

Hi All,

There have been tons of threads on getting more local area maps.
So lets try to work together and get it done.

We started a github wiki to collect links to PDFs we have found
that need to be digitalized.

How should we do this? Who can help?

[datameet] Re: Map Digitalization Effort

[Sharad Lele]

Dear Nisha,

Can you take the csv given by Justin, and create an online spreadsheet, 
with columns indicating URL for source pdf /jpeg, whether digitized or not, 
if not then who is taking the lead on that city, and URL of final 
shapefile something like that...?

I can contribute shapefile for Coimbatore city ward boundaries also, if I 
know where to send it/upload it.

Ideally, we would want pdfs and shapefiles all sitting in parallel folders 
in the same location? 

Sharad

Re: [datameet] Census Ward Boundaries for Metro Cities

[Sharad Lele]

Mahroof:

We followed up on this pricelist. Turns out it is bogus: they are refusing 
to give any map using that pricelist, saying that maps don't exist, that 
list is out of date, etc etc.

But I like Nisha's basic idea: we get hold of the pdfs as and when we can, 
and digitize and put them in the public domain.

We have done it for Bangalore. Maybe same location can be used to archive 
for other towns as well. I can provide files for Nelamangala and 
Ramanagara. Slow process (if you think of the number of towns in India :-)) 
but what else to do?

That is how we got them for Nelamangala (through the CEO of the 
municipal council).


Ramanagara Commissioner was totally non-cooperative--threw us out.

Have you put the Hubli-Dharwad map out in public domain? You should.

Here is an update from my colleague who tried to get these maps:

/I called Delhi folks. Apparently, town with ward boundary maps are not 
available for public dissemination at the moment for any state. He asked 
me to purchase the state map book (which is available online) for the 
all the maps they have. /


Clearly, RTI is called for.

Dear Sudheendra:

Well, you know how right hand does not know what left hand has done.

Please see the ppt that Census person made to NSDI in 2011:

https://*nsdi*india.gov.in/ 
<http://india.gov.in/>*nsdi*/*nsdi*portal/*nsdi*10/presentations/*census*.pdf


They claim to have ward boundaries for more than 7,000 towns

I know that Hubli-Dharwad recently commissioned a company to generate 
shape files for their wards (that data is soon going to be made 
available). But if it already existed, they wouldn't have needed to.

Dear Nishadh;

Many thanks for pointing us to this link, where the 2011 pdf maps
have now been uploaded.

1. I could not find any urban ward-level boundaries in the pdf. I
only see taluk-wise or tehsil-wise maps in which village
boundaries are shown, and also the urban area is marked as a
whole. But no ward boundaries within the urban area. Am I missing
something?

2. About shapefile: Ah! this is the eternal battle! As I said in
an earlier post, census MUST be having all these boundaries
digitized, and has in fact boasted in an internal presentation
that they have sub-ward-level maps. But they refuse to acknowledge
that when we approach them. Maybe someone should file an RTI.

The original claim that Census has all these maps was made on the basis

states in detail what mapping work Census has done for 2011 census. 
Please look up the first post in this thread.

Hi Mohit:

Thought I will mention that 2011 village amenities tables have now be 
posted by Census of India: 
http://www.censusindia.gov.in/2011census/dchb/DCHB.html

While the village boundary maps are still not included in the pdf, the

the Village Amenities (DCHB_VillageRelease) files. 

Might be of use in updating.

I know that in all the states where census sub-districts

of TN), the census sub-district is identical to the
administrative block.

I've already completed a mapping exercise for Bihar using
the census sub-district map and the data matched up
pretty well. If the IND_adm3 data is indeed the
administrative blocks then I could do a similar exercise
with Madhya Pradesh. I'll take a look to see if the data
lines up correctly.

Has anybody dug into this issue any deeper? I've heard
that tehsil comes from the revenue side whereas taluk,
mandal, etc comes from the administrative side but that
doesn't explain why the census uses different
sub-district units across states.

Re: [datameet] Re: 2011 subdistrict Maps

[Sharad Lele [शरच्चंद्र लेले]]

Khaliq:

I have seen similar materials for karnataka and tamil nadu (including 
also the village amenities directory, which is a mine of information).


You are right that if one is to buy this for the whole state, it is 
quite a bit of money.


But the bigger tragedy is (as I had said in a post not so long ago) that 
Census has, in its 2011 exercise, also created a GIS division that has 
converted all the boundaries in your pdf file to GIS format, and also 
gone and mapped down to the level of individual dwellings in many 
cities. They boast about this in a ppt that is available online which I 
had circulated, but they do not respond to any requests to make this GIS 
data base available (for free or for payment).

When you say they 'sell it', i presume you are referring to the
location codes created in each census round and the tables that
link one to the other? in which case Sumit Mishra has already
posted the all-India dataset for this, right?

Yup, they do. I have all of Maharashtra and all of Bihar, and
I can acquire the rest too. I can gather it all and upload it
(approx 6-8 GB) if something comes out of it.
