[datameet] Re: Coastal DEM Data

[Naraina Damle]

Since you are talking about COASTAL DEM I think it will look good only when 
it includes Bathymetry  data also. 

The best or rather the only source (i know of ) of Bathymetry data is 

GEBCO ... 
https://www.gebco.net/data_and_products/gridded_bathymetry_data/

It includes land data also. 

For only land data currently the best source is  

JAXA

[datameet] New link to the datasets uploaded by me (Damle)

[Naraina Damle]

Dear All, 


I have shared different data like maps and census over the years on this 
forum
all that data is still there intact on my google drive. 

However the old links are no longer valid due to some changes at Google. 

I am not so active here these days hence I have not replied to many 
requests. 
My sincere apologies for that. 

Now I  have   clubbed all that Data under one folder and here is the link . 


https://drive.google.com/drive/folders/0Bw9Ef2_V5qDeOTFwV1U1WDA5Rnc?resourcekey=0-j_UVlIHfQUnzxfr_SD0UYA=sharing

I will put a newer Readme file later and reply to individual requests but 
you can use the data immediately. 

To the best of my knowledge none of that data had any copyright 
restrictions unless specifically mentioned

Regards 

Naraina Damle 
.

[datameet] Re: where can I download India boundary with the Indian States? with missing states in other file?

[Naraina Damle]

Hello, 

This data was made available sometime back on the SOIAPP by Survey of India 
https://indiamaps.gov.in/soiapp/


but they seem to have discontinued the download feature.
I had downloaded from there. 
You can find it here on my Google Drive

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

[Naraina Damle]

Found it. 

Download local government Directory from this site. 

https://lgdirectory.gov.in/

This is one of the best and easiest dat ato download. Its LOCALBODYMAPPING 
file has both 2001 and 2011 numbers with their own new numbers for villages 
added after 2011

There is a difference in the Village numbering in 2001 and 2011. Let me 
check what is the solution.

[Naraina Damle]

I have shared PCA data for the entire country sometime back. 
Here is the link to the folder on my personal Google Drive . 

https://drive.google.com/drive/folders/1CNh5oaX3efZbW4yo8GXqbufjy57cMR09?usp=sharing

I do not know if it has been added to the repository. It is made by me only 
from census website data. It could have errors. If found let me know.

Re: [datameet] Help in extracting Mumbai's Development Plan 2034 as Shapefile

[Naraina Damle]

Hello, 

Some thoughts after reading the various comments. 

I have worked on similar data for Delhi about 10 -12 years ago. 
Things might have changed now. But I guess the following. 

NIC (National Informatics Center) started with the original base data. They 
have very very strict data sharing policies. 

The vector data in based on NIC servers. They serve it to Municipalities 
and strictly monitor the usage. 
Municipalities draw on top of the base layers. The condition is that they 
can not even share that Drawn data with anyone outside a designated ROOM in 
soft copy.

If they find violations they will stop serving Vectors (in case of Delhi 
DJB they were serving vector base layer data to DJB) and only serve 
Rasterized base data. 

I earned some money in a project to RE-Digitise DJB's own drawn layers from 
Paper Prints to give to a consultant.

 this is much much better that Paper prints.

 Hi,

 Great to know they're finally moving from PDFs to zoomable maps! One 
 thing I had really hoped for was for people to pin-point exact locations 
 in 
 the DP and talk about that, instead of just making grand reports with 
 overall stats.

 So again the data you see on this site is coming from a map server that 
 pre-renders the data and sends stuff across as broken down image tiles.

 Precisely to prevent site visitors from scraping the original vector 
 data.

 I'm guessing the bureaucracy would have consented to this move (from 
 PDFs to actual map) only under strict conditions that it must not be 
 scrape-able.

 All the best.. if somebody does find a way to break through though, I 
 can imagine the whole thing will be taken down and that will be 
 regrettable, because this is a really good leg-up for the urban planning 
 sector in India and I'd like to see the same happen in Pune as well. 
 Between PDFs and this I prefer this even if both options aren't open.

 A longer approach could be to share examples from Europe/US of cities 
 releasing such full data openly and persuade/petition these folks with 
 that. Again, all the best for that. And when one

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

[Naraina Damle]

I would like to add my two cents to this discussion. 

You need to read, study, learn and practice this stuff about Coordinate 
System and projections. 

You can always land up in surprise\ing situations. 

One thing I would like to mention here is to Split the thing in Two Aspects 
: DATUM and PROJECTION and understand the difference between the two. 


Simply stated just saying "WGS84" is not complete. It is only talking about 
Datum and not projections. 

DATUM DECIDES WHAT IS THE PRECISE LATITUDE AND LONGITUDE OF  A PLACE. 

As per WGS84 the ZERO Longitude is NOT at Greenwhich line  it is a little 
away. 

https://gis.stackexchange.com/questions/88428/why-is-the-gps-reference-meridian-100m-to-the-east-of-the-prime-meridian
 

One needs to Know and use Datum even if you want to make a Map on a 
Actually Sphere / Globe. But in this case you do not need projection. 

PROJECTION DECIDES HOW YOU ARE FLATTENING THE SPHERE/ PART OF IT TO SEE IT 
ON A FLAT MAP. 

So in case of a Flat map You need to be careful about DATUM as well as 
PROJECTION. 

Datum is required because there were historical maps made with Datum other 
than WGS84.

.. This is just a simplified way but it is more complex. I am a 
permanent learner.

Naraina Damle

[datameet] Under which Indian state do these Bay on Bengal Islands come?

[Naraina Damle]

Hello, 

I was just trying to study the OFFICIAL SOI Shapefiles downloaded from 

https://indiamaps.gov.in/soiapp/

I find the following Islands shown in the Country map but not in the State 
Map. 

Does someone have any idea?

Logically they should be under WB 

but they are not shown as such. 

Is it a mistake or am I wrong somewhere?

[datameet] Re: 2018 India Village GIS Data Project

[Naraina Damle]

Yes, 

But I think it is better that people who handle that should do it.
I do not tamper with the GITHUB Uploading. I am not that proficient in its 
working.

[datameet] Re: 2018 India Village GIS Data Project

Hi Dhaval, 

Actually I keep doing things in an Intermittent manner. 
Then I move to something else. 

However I keep all my data safe. 

Here is the link to the Datameet folder on My Google Drive. 

There could be other things at other places. But Gujarat Data is here.

Here is the google drive link

https://drive.google.com/file/d/1sTzYtf-6E2tzdfdF6em-xJhRuBk-6Bo8/view?usp=sharing

Though it looks like Raster file visually the data can be copied and pasted 
as text. 

You will have to do the cleaning after that.

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

[Naraina Damle]

[image: 1981_2.png]


I think there is not much data on the older census (1981 and before) 
available in editable form. 

However census website has an old census page 

I had downloaded some PDF file from there. 

I have a pdf file named 26745_1981_PCA which is 782pages and 13 MB

These are two screenshots from that file 

[image: 1981_1.png]



I will try to see If I can locate a link. 

Or else I will share the file over Google Drive. If it seesm useful

True, 

But now I think it is more difficult to convert them back to a Processable 
Data. IMO

It is basically for human (visual) consumption. 

That is good

Hi, 

Just updating with a recent find.

Now they have a captcha before you can download a pdf and the PDF itself is 
Rasterised.

not.

[datameet] Re: Building footprint shapefile

[Naraina Damle]

HI, 

My answer may not be useful hence I did not answer earlier.

let me answer from different points of view. 

1. You need a FREE ( I Guess) vector map of building footprints of Delhi. 

Now the question is,  does such a data exist .. The answer is YES. 

Is it free ? Highly unlikely. 

I have been gathering almost every free data out there from internet since 
about 2000 and have not seen a free data with individual building 
footprint. 
Nearest that is available is populated area boundaries.


2. Where does a Building footprint Data for Delhi exist, If at all? 

 YES, This data exists and it is with NIC. National informatics centre. 

They give this data to other government agencies for GIS purpose. But they 
try to protect with all their might. 

I have seen this data myself and worked on a derivative as a subcontractor 
for a government department.
But it is was served through NIC servers in a Room in the client department.
They were not allowed to access that data and  even data they created 
themselves for their own purpose outside that room. This was about 10 years 
ago. 

Do not know the present situation.
