[datameet] Residential houses, Apartment, Commercial and Malls in any AOI through OSM

2022-07-13 Thread Ravi Chopra 
Hi I need a help to extract number of
1) Residential houses, 2) Apartments, 3) Commercial spaces (for offices)
and 4) Shopping Malls.

This is required to estimate water consumption demand in any location.

Any help would be appreciated.

Thanks
Ravi

Re: [datameet] Re: NEW DISTRICTS OF INDIA SHAPEFILE

Great Work  Dutta. You have always helping with your hard work on this 
platform. Is there a place where we can get updated villages shape files as 
well. 

I tried merging updated village data from multiple sources. Not sure how 
accurate it is. Sharing sith you if you could help improving it on open 
platform.

[datameet] IMD Pune Gridded weather data processing

2022-07-13 Thread Nikhil VJ 
Hi,

(replying to this thread
 with a
changed subject line)
I searched on net for how to extract the imdb gridded data (Sai Kirshna
thanks for ur program too)
And I found this video: https://www.youtube.com/watch?v=40Dvj6MwGTs by
OpenGeoLab  channel on youtube (done
some pretty good training work in GIS!)

Mentions: "imdblib " python
package.. and it looks like that one takes care of a lot of the complexity
for us! Big thanks to Saswati Nandi  who
authored it.

With a bit of looking up

I was able to bring the data out to a simple flat table format that we all
know and love.

Sharing the code of a sample extraction here:
https://github.com/answerquest/IMD-grid-data-work/blob/main/2022-07-13%20IMD%20Gridded%20data%20extraction%20sample%20flow.ipynb

I took out some data for nearby Pune, and have done a quick viz in this
google doc:
https://docs.google.com/spreadsheets/d/13j3kMvGdr52_dX-4nG9YDFCu3ZO_sYadFmYeiZJVgWo/edit?usp=sharing

*Observations:*
1. There is a lot of junk data in there : for 1950s yrs that I saw it was
over 60%. Fixed values like -999 are filled in where there wasn't any
reading for that particular place and date - probably because the data
system being used couldn't work with nulls. So it's important to get rid of
the junk data points before moving forward.
2. If I 7z-zipped the flat table csv after removing the junk data, and
whadyaknow, the result is smaller. (tip for folks managing this department
in IMD. Also, check out HDF5 format)
3. There's 3 data items: Max temp, min temp, rainfall.
4. Temp data is resolved to .5 lat-long points and available from 1950.
Rain data is resolved to .25 lat-long points and available from 1901.

*Next steps:*
As usual I'm going to setup a week-long script (going year by year only,
with plenty of pauses so that it doesn't overload the IMD site, mind!),
extract it all and load it up into a Postgresql DB / API etc for accessing.

*Would anyone out there like to collaborate on a visualization?*
We have data that is in point lat-long form, and is temporal with date-wise
resolution.
So, map-based combined with time series and/or animation would be good.
