[datameet] Re: village boundary layer for Karnataka
Sharad, Thanks for uploading this. I have looked at this and compared to a few other datasets. I have a question about a location in your dataset and how it lines up with census data/ codes. LOC_CODE: 15103000 NAME:Krishnarajasagara Nac If you go to the Census Digital Library (http://www.censusindia.gov.in/DigitalLibrary/Tables.aspx) and look at the 2001 table for the Mandya District, the first records in the table read: STATE DISTRICT SUB-DISTT TOWN_VILL WARD EB LEVEL NAME TRU 29 22 0 0 DISTRICT Mandya Total 29 22 0 0 DISTRICT Mandya Rural 29 22 0 0 DISTRICT Mandya Urban 29 22 42205000 0 0 TOWN Krishnarajasagara (NAC) Urban 29 22 42205000 1 0 WARD Krishnarajasagara (NAC) - Ward No.1 Urban I have seen SUB-DISTT codes of before for states, districts, and very large cities (i.e. Hyderabad) - but this is something new!? I believe the census table is wrong. But something that is kinda throwing me off as well is your data has two of these, both with identical records, and the same Taluk, but you can see i think it should be split (but not certain)? https://lh6.googleusercontent.com/-KIM29wpLGWs/VBBjJABRYAI/ALY/46VKKJX5oFE/s1600/mandya_error.jpg a last thing to throw in the mix is that in a different census gis dataset, the north part has :2922000302365700 Chikkayarahalli and the south part has 2922000402378200 Hongahalli - these are both in the census table as well... Can anyone make sense of this!?? Thanks! Justin On Thursday, August 21, 2014 1:34:07 PM UTC-4, Sharad Lele wrote: Dear All, I have uploaded a village boundary layer for Karnataka (shapefile format).

[datameet] Re: village boundary layer for Karnataka
Hi Justin, Thanks for pointing this out. I am sure there are a few other such errors in our layer--as mentioned in the readme, it was digitized from maps in census of india district handbooks, and those maps contain other confusing features such as roads, which may get mis-digitized. I don't have an immediate response beyond this. It will take me a while to get to the nittygritty. But others are welcome to point out more errors. The only tragedy here is that we are all reinventing a wheel invented at least 3 times before: village boundaries have been digitized by state Remote Sensing Application Centres, by individual departments when they need them, and now (as mentioned in a separate post) by Census!

Dear Mr. Lele, Nice datatset I have converted the dataset to kml file for the reference of the people who may want to view it in Google Earth, I have just converted it as it is. here are the links for download http://tinyurl.com/qem2r4b readme copy is here http://tinyurl.com/q5hj25x Rgds Dilip Damle On Thursday, August 21, 2014 11:04:07 PM UTC+5:30, Sharad Lele wrote: Dear All, I have uploaded a village boundary layer for Karnataka (shapefile format).
