Re: [datameet] Re: Food Security data - Public Distribution System

[Prk]

Hi Daniel, 

Thank you for this. 

This bulletin does not mention distributed amount explicitly but it does 
mention Allocation and off take by states. I may be wrong but I think 
offtake is indeed what is distributed by the government. I will recheck 
this nonetheless. 

The online reports do go back till 2009. I am working on a dataset 
currently but I will start putting them in excel afterwards. 
In case you or anyone else already have it, it would be great to share with 
all. 

Thanks
Regards,
Purnima

Re: [datameet] Re: Facebook Road AI data!!!!!!!!!!

[Nikhil VJ]

Hi Devdatta, Ujaval

Thanks! Both ways look good. I got the ogr2ogr way working, but QGIS
processing toolbox way looks promising too.

Hi Deepak,
That would be an unfair question to ask as the intention for FB to share
the dataset is "this is what some of our programs have come up with by
looking at lots of satellite imagery data etc. It might help you map roads
that may have been missed so far, please see and check for yourself".

So this is at an initial stage in a very long process. The reason why such
initiatives exist is because there is no definitive "all rural roads"
proper source.
And whether the data does help or not may change from place to place with
local condtions like soil color, tree cover etc impacting the ability of
the programs in interpreting satellite imagery. So there can't even be any
definite answer at centralized level - it may be helpful at some place and
not at others - people will have to dig in and find out.
