We talk about #DigitalIndia & every other meeting someone would claim that data is the new gold etc. But when it comes to critical data& good quality data, India is far far behind..
Eg: India's open data platform- data.gov.in provides the locations of hospitals
Location quality of many of these hospitals are not very accurate and 250 of them are mark outside the country!
The reason being is that they have automated geocoding using Google Maps
Why this happens: When done at a global scale, Google Maps API tries to read the address and gives the most "relevant" result. So D C Bank road (probably district cooperative bank) is marked in Washington DC
and Oxford Public School is marked in Oxford, England
Within India also, the data is not complete nor does it give right locations.
Take a look at this - Hospitals from Karnataka, Andhra, Kerala , Madhya Pradesh etc are marked in Tamil Nadu!
The error is not jut because of geocoding, it also sometimes is rooted in the core data itself from NHP. Case in hand: SugamPriya hospital which is in Kamarajar Salai, Karaikal has been recorded in the sheets as Karnal, Haryana
Many of them are marked right but a good amt of them are not. If this kind of automation was done by an individual researcher,an institute or a consultant co, I totally understand
But Govt shouldn't be doing these. Govt should collect proper ground data, manually verify & upload

I had earlier posted that I am not confident about Covid Nos & few asked explanation
Attaching satellite images where SWIR bands have picked up fire signals in crematoriums(orange colour). In most cases, this is 1st time detected or ten times intensity detected in past
Images from NOIDA, Vrindavan, Mathura, Lucknow (Clockwise from left top)
Orangish -red colour is the place of the ghats where these cremations take place
DhoriGhat, Baksar, Bhitoura, Fatehpur Ganga (These are Mild Signals)
May had been asking me whether Isha encroached forest lands. IMO this is deviating from actual issue. Read full thread
Isha didNOT build on forest dept lands as such but it VIOLATED rules in other ways
Old Satellite image & map show that it was not forest but revenue land
Inorder to protect out environment, we had framed laws to secure permissions from necessary authorities. Since it was farmland and since it came under Hill Area Conservation Authority, necessary permissions were to be secured from respective offices
In their webpage, Isha says that they secured permission to construct statue on Sep - Nov 2016. But prior to securing permission itself they started constructing. Attached #Satellite images from Jan & Feb 2016 show that construction had already started before securing permission
There was a Madras high court order on lake encroachment & judge said "whether it is 112 crores or 1K crores, we will destroy it. Get bulldozers ready"
But my lord, Madurai Bench of Madras High court was constructed in lake
Old Satellite image attached 1/n
And may be we'll get justice from the lower district court in Madurai. But that is also built on a lake
May be we should go even lower to the law college... But law college is also on a lake
A Kutty (Short) Story with Satellite Images about a hamlet near Tirunelveli, #TamilNadu
In 2003, the hamlet can be seen (marked in orange). It is next to Tirunelveli - Madurai railway line. There's a crossing (marked in black) through which people went to the nearby main road
Around 2018, Railways decided to build an underpass for this village so that they can double track this corridor. Concrete boxes can be seen in the image
And they started constructing the underpass by digging as seen in this satellite image
