Geospatial folks in India: given the recent talk of liberalising access to geospatial data, can we, in this thread, list civilian-use geospatial datasets available with governments, that, in your view, must be made freely available to for public use?

I’ll go first… PLEASE ADD
A single authoritative, official and regularly updated GIS-ready dataset of all political and administrative boundaries, from international boundaries down to revenue village/ ULB ward boundary.
Analysis-ready time-series of the NRSC’s 1:250k and 1:50k Land Use Land Cover datasets. (By analysis-ready, I mean GeoTiffs, not via WMS, as currently available).
Analysis-ready time series of the Forest Survey of India’s forest cover and forest type maps produced for the State of Forests report.
Analysis-ready time-series of the Wasteland Atlas of India by the Dept of Land Resources.
Raw daily time-series datasets of weather variables from geolocated weather monitoring stations of the Met Department.

The unlikely, inspiring and heartwarming story of an online Kannada-English dictionary, Alar/ಅಲರ್, alar.ink:
Every so often, an unfamiliar or difficult Kannada word catches me without a dictionary at hand. Earlier, I visited a website called KannadaKasthuri, with a decent Kannada-English (& KN-KN) dictionary. Its now gone & I’ve disliked the alternatives. Then, I stumbled upon Alar…
Alar/ಅಲರ್, alar.ink, is a brilliant site: exhaustive, simple, fast and ad-free. That’s not all. Its word corpus is completely open. The algorithm that does its phonetic indexing is open source. So is the software that drives it. But its story only gets better…

'@Ram_Guha’s piece in @ttindia on music transcending prejudice and bigotry, emphasising the syncretic nature of art, took me to a time earlier this year when I sought solace in just such a tradition, and went rooting around YouTube for examples. (THREAD)

telegraphindia.com/opinion/indian…
As Delhi burned, I found succour, even escape, in seeking examples and reminding myself of an (endangered) artistic tradition that routinely went beyond mere tolerance, well into reverence and celebration even, of identities and symbols other than its own.
Yet, even as they sometimes deigned to rise above religion, classical artistic traditions have reproduced and perpetuated other abominations in our society, prominent among which is caste. With this important caveat, it is still instructive to seek a glimpse into its syncretism.

Today, apparently, is World Migratory Bird Day.

As good a day as any to marvel this little bird. It is called the Blyth's Reed Warbler. Not much of a looker, but it is one hell of a traveller. Here's this migrant's story…

As seasons roll, plants in every corner of our planet pulse to the changing regimes of light, temperature and moisture. When these conditions are ideal, plants put out an exuberant flush of green. To a satellite, here is how the seasonal waxing and waning of vegetation appears.
At different times of the year, different parts of our planet are becoming greener than they are on average (black), or even browner than they are on average. As this green wave breaks over a place, it comes alive with a myriad life forms, including insects that depend on plants.

THREAD: We hear that India is not testing enough for COVID19.

During April, our testing rates (line thickness in chart) grew c.11 fold: from 36 to 401 tests per million. Case detection rates (y-value), however, increased more slowly from 34 to 43 positives per thousand tests .
But that does not tell us enough about testing and case detection patterns across the country. Our states are very different, and so are their responses to the outbreak.

So, here are the patterns for our top 15 states (by cases), w.r.t. the national aggregate shown above.
States in the top row account for nearly two-thirds of all cases. Currently, they’re testing at twice (847/mn) the national aggregate rate (401/mn), & have case reporting rates that are 50% higher than the national aggregate (with the exception of Rajasthan, which is 38% lower).

A symposium in the memory of Ravi Sankaran? What a bad idea, I thought. Not just because I could almost hear Ravi’s booming voice in my head saying: ”I don’t see the bloody point of having a stupid meeting to honour a dead person.” But also because… (1/n)

I couldn’t fathom how, if ever, one could honour the memory of a complete maverick like him. Sure, you could remember what he did, how he went about it, and recall its impact. Recollect how he learnt about a sobering conservation situation and jumped right in. (2/n)
How he always unafraid to ask the most basic questions. How he did absolutely anything it took—enduring endless physical hardship, acquiring every skill necessary, or suspending all moral judgement—to gather data meticulously but also impartially. (3/n)

As India waits anxiously for the #monsoon to break over a parched subcontinent, here’s a look at the advance and retreat of the 2018 monsoon. #EarthEngine@googleearth⁩ ⁦@EarthOutreach
As the #monsoon clouds drape and dance over the subcontinent (see tweet above), beneath those clouds, an entire parched landmass bursts into life as the rains fall. See for yourself why the monsoon is truly the beating heart of India. #EarthEngine @googleearth @EarthOutreach
@googleearth @EarthOutreach In the pre-#Monsoon half of the year, south India seems to have suffered a greater rainfall deficit this year (i.e., more orange than blue) than the last. Consecutive deficit years for Gujarat and Maharashtra, whereas north India seems marginally better off so far this year.
